Understanding Hydraulic Loading in Wastewater Treatment Plants

Posted on by Priyanka Khaire

With global water consumption increasing by nearly 1% per year due to population growth, industrial expansion, and climate change, wastewater treatment plants are under mounting pressure to handle rising hydraulic loads efficiently.

Studies show that extreme weather events, including heavy rainfall and flooding, have intensified hydraulic surges in wastewater systems, often exceeding design capacities.

A 2024 report from the United Nations highlights that nearly 80% of the world’s wastewater is discharged untreated, with hydraulic overload being a significant challenge in both urban and industrial treatment facilities.

Innovations in adaptive wastewater treatment, including the integration of AI-driven monitoring systems and bioaugmentation techniques, are emerging as critical solutions to optimize plant efficiency and resilience against fluctuating hydraulic loads.

Wastewater treatment is one of the most important needs of the 21st century.

The population explosion, rapid urbanization, industrialization, and changing lifestyles all across the globe have contributed to the generation of a large quantity of waste.

Wastewater poses a serious threat to the human population, animals, plants, and the environment if left untreated.

Therefore, wastewater treatment plants need to be efficient and perform at their best always.

There are several parameters that help to gauge the performance of a wastewater treatment system.

One of them is hydraulic loading.

In a wastewater treatment process unit, hydraulic loading is known as the volume of wastewater applied to the surface of the processing unit per time period.

Wastewater treatment systems often take loading rates to determine if the system may or may not clog.

For example, at a given location or residential area, the unit water consumption of a place has to be determined because it translates into the amount of wastewater generated in the area.

Depending on the sanitation facilities, wastewater discharge process, and sanitary habits, the hydraulic load of the treatment plant located at that place can be determined in a given time frame.

Several factors like population growth, development of water supply systems, and sewage systems have caused the amount of waste generated to increase.

It has propelled wastewater inflow to the treatment plants to the maximum limit and beyond.

In other cases, water outside of sewage, like rainwater, may run down and increase the average inflow of wastewater every day.

It may lead to hydraulic overload, affecting the performance of the system.

Also, wastewater treatment systems should be able to handle the variable flow rates of wastewater and daily fluctuations effectively.

It has been observed that peak influent flow rates, suspended solid loading, and BOD sometimes rise three times more than the average value.

Therefore, it is important that treatment systems can withstand such stress in unsteady conditions.

In a wastewater treatment process, biological treatment or secondary treatment of wastewater is the most important process.

The natural microorganisms break down the organic waste present and release carbon dioxide and water as the by-product of the degradation process.

This process is essential to attain the standards based on which the effluent is released into the environment.

Aerobic Wastewater Treatment

An increased flow rate that is beyond the capacity of the treatment plant can cause problems.

In such cases, wastewater may reach those zones in the system where natural microorganisms are absent or unreachable.

At the same time, the severe hydraulic load can affect the performance of microbes as well.

Such stress can cause cell death of conventional microbes.

It may lead to deterioration in the quality of effluent released.

A large amount of accidental water in-flow to treatment plants always causes a variable volume of wastewater to be processed.

Upgrading or re-designing plants to handle hydraulic overload is not viable as well as feasible.

Therefore, urgent innovative solutions can be used to improve the performance of wastewater treatment plants.

Organica Biotech is one of the leading companies with highly effective wastewater treatment solutions.

Cleanmaxx Aero is one such product that consists of specialized strains of microbes.

It can survive in the wastewater and perform the waste degradation function under shock loads like hydraulic loads and organic loads.

It minimizes sludge production, helps in BOD removal, and prevents noxious gases like ammonia.

You can use Cleanmaxx Aero to improve the performance of wastewater treatment plants and negate the effects of hydraulic loading.

How To Remediate Oil Contaminated Soil

Posted on by Priyanka Khaire

Global oil pollution remains a pressing environmental challenge, with an estimated 1.3 million tons of oil spilling into land and marine ecosystems every year.

According to a 2024 study by the International Journal of Environmental Science, oil spills have contaminated over 20 million hectares of land worldwide, reducing soil fertility and threatening biodiversity.

Emerging research highlights that conventional remediation methods, such as excavation and chemical treatment, not only have high costs but also risk secondary pollution.

This has led to an increased focus on biological solutions, with microbial bioremediation gaining traction as a sustainable and cost-effective method.

Recent advancements in bioaugmentation have shown up to 80% faster degradation of hydrocarbons compared to traditional methods, making it a promising solution for large-scale soil restoration.

The energy demand has seen a sharp rise in the last many decades due to the increasing population and modernization of society across the world.

Petroleum oil is one of the most important resources that fulfill today’s energy demand.

However, it is found to be one of the major pollutants in the soil and the reason behind environmental deterioration.

Various offshore and onshore petroleum industry activities, such as production, transportation, storage, and management, suffer major and minor accidents that cause oil spills.

Moreover, refining and further processing petroleum to develop derivatives may also lead to leakage from pipelines, tanks, equipment, etc.

In the past decades, the world has witnessed massive oil spill incidents like that of the U.S. Gulf of Mexico, the Deepwater Horizon disaster, the Mauritius Oil spill, the recent oil spill in the Gulf of Mexico, and many others.

This has drastically affected the environment and remains a major global concern.

Moreover, it is toxic to humans and animals and adversely impacts plant life due to contamination of soil.

Petroleum primarily consists of a mixture of aromatic hydrocarbons, aliphatic hydrocarbons, heterocyclic hydrocarbons, and non-hydrocarbon compounds, which are mostly biodegradable.

It affects the soil by disturbing the chemical balance, inducing oxidative stress, and causing low nutrient availability for plants.

Additionally, it is found that petroleum oil contamination affects processes like seed germination, photosynthesis, nutrient assimilation, and root development, even resulting in plant death.

The presence of toxic and carcinogenic elements in petroleum oil and its derivatives can contaminate the food chain and cause dangerous diseases like cancer, nervous system depression, and other ailments in humans.

Various methods have been researched, devised, and implemented to remediate the soil contaminated by oil.

It includes physical, chemical, and biological removal of contaminants.

The physical and chemical methods include incineration, landfilling, thermal desorption, cement kiln, etc.

But they have multiple disadvantages.

The excavation cost, transportation of contaminated soil for ex-situ treatment, and labour-intensive work make it expensive.

Also, the practical application of these techniques seems to be difficult.

Additionally, it has been found that physical and chemical methods destroy the natural soil microorganisms and affect their ecosystem.

Thus, bioremediation has emerged as one of the most preferred methods for the remediation of soil impacted by oil.

Bioremediation

Bioremediation can be defined as the process in which natural living microorganisms are utilized to break down the pollutants present in the soil.

It is known to degrade, detoxify, and transform pollutants into harmless substances, turning the soil into its native environment.

It is regarded as one of the most sustainable methods to remediate soil pollution by oil.

Moreover, it is cost-efficient and effective.

Different strategies like phytoremediation, rhizo-remediation, biostimulation, and bioaugmentation are used.

However, there are certain challenges with the bioremediation of contaminated soil.

It is generally perceived to be time-consuming, and factors like temperature, pH, oxygen, and salinity impact the bioremediation of the petroleum-contaminated soil.

However, there are innovative and simple solutions that can help overcome these challenges.

Organica Biotech is one of the leading companies in the field of efficient and effective oil and soil bioremediation solutions.

Bioclean FOG is one of the best solutions for fast bioremediation of soil.

The bio-augmentation strategy is used when the formulation of a microbial community helps degrade hydrocarbons and other pollutants.

Thus, you can use Bioclean FOG to boost soil bioremediation.

Septic Tank Maintenance – How to Break Down Organic Solids in a Septic Tank

Posted on by Oscar Peter

Septic systems remain a critical part of wastewater management, serving nearly 1 in 4 households in the United States alone.

Globally, an estimated 2.5 billion people rely on septic tanks for sanitation, according to the World Health Organization (WHO).

However, poor maintenance and ineffective waste breakdown contribute to groundwater contamination, with nearly 30% of septic systems in developed countries failing due to sludge buildup and blockages.

Recent studies highlight that biological additives enriched with enzyme-producing microbes can accelerate organic waste decomposition by up to 60%, reducing the need for frequent pumping and preventing system failures.

With rising concerns over water pollution and sanitation challenges, advanced septic tank treatments are becoming essential for sustainable waste management.

The French are believed to be the first to use septic tank systems in the 1870s, followed by the United States.

Over a century later, septic tanks are still used worldwide at homes without access to sewage treatment plants.

A septic tank, made of concrete, plastic, or fiberglass, is installed beneath the ground and performs the function of breaking down waste generated from the household.

A malfunctioning system can cause a wide range of problems, such as surface water pollution, disease outbreaks, and environmental concerns.

Therefore, your septic tank system needs regular maintenance and care to work at its best and break down organic waste efficiently.

How Septic Tank Breaks Down Organic Solid Waste

A septic system generally consists of pipes, a tank, and a drain field.

It mainly helps in breaking down organic waste material and the sedimentation process of solid waste.

Living microorganisms play a key role in the biological decomposition of organic solids, which are then safely disposed of in the environment.

Ideally, the septic tank waste decomposition consists of the following process:

  1. Wastewater generated from the bathroom and human waste from the toilet flows into the septic tank through pipes.
  2. Millions of microorganisms available naturally in the tank break down the organic waste.
  3. Solids settle at the bottom of the tank and form a sludge layer, whereas liquids such as fats, oils, and grease float at the top.
  4. The treated liquid, known as effluent, flows out of the tank into the drain field.

However, septic tank systems sometimes fail.

Unable to break down the organic solid waste can cause backup issues at your home.

Moreover, the untreated effluent may contaminate drinking water, attract vectors, insects, and rodents, cause bad odour and disturb the aesthetics.

Several factors that contribute to septic tank failure can be avoided if homeowners strictly follow the maintenance measures.

For example, using too much water than what the system can handle may lead to failure.

A large quantity of water from showers, toilets, and laundry disturbs the balance in the tank and affects sludge-scum separation.

Non-biodegradable waste materials should not be flushed down the drain.

Many such substances do not decompose easily, stressing the septic system.

The disposal of excess chemicals into the septic tank can affect the system’s performance as it may eliminate beneficial microorganisms.

Furthermore, chemicals can contaminate groundwater too.

These preventive measures mentioned should help in septic tank maintenance.

However, one of the best ways to support the breakdown of organic solid waste and minimize sludge build-up is by using biological septic tank treatment solutions.

The biological additives help by enhancing the growth and performance of the microbial community available in the septic tank, eventually boosting the waste decomposition process.

Additionally, homeowners can opt for easy-to-use and affordable biological additives for routine maintenance of the septic system and avoid costly mechanical maintenance like pumping.

Organica Biotech is a leading company that provides advanced septic tank treatment solutions.

Bioclean Septic is an excellent, eco-friendly, and effective septic tank cleaner that is highly capable of breaking down organic waste efficiently.

It uses enzyme-producing bacteria to accomplish the objective of waste decomposition and minimizes sludge build-up.

Bioclean Septic is the best solution you can use to keep up the performance of septic tank systems.

Sustainable Aquaculture: Why Is It the Need of the Hour?

Posted on by Oscar Peter

The global aquaculture industry is witnessing unprecedented growth, with production expected to surpass 109 million tonnes by 2030, according to the Food and Agriculture Organization (FAO).

However, this expansion comes with sustainability concerns, as nearly 30% of aquaculture systems face challenges related to water pollution, disease outbreaks, and inefficient feed utilization.

A 2023 study in Nature Sustainability revealed that intensifying aquaculture without sustainable practices could increase greenhouse gas emissions by 32% by 2050.

Moreover, antibiotic overuse and habitat degradation threaten long-term industry viability.

To address these issues, sustainable aquaculture is emerging as a necessity rather than an option, integrating eco-friendly aquaculture solutions, biosecurity measures, and optimized feed management to ensure environmental and economic resilience.

Over the last few decades, the fisheries and aquaculture sector have seen a dramatic change in its dynamics with an overall expansion of production capacity, trade business, and food consumption.

Although the capture fisheries show a little stagnation trend for a few decades, the aquaculture sector is booming.

Emerging aquaculture production systems have a significant potential to curb global food security problems and to meet human nutritional needs with improved environmental performance.

“Aquaculture production is predicted to increase by 32%, from 26 million tonnes in 2018 to 109 million tonnes in 2030.”

What is Sustainable Aquaculture?

Sustainable aquaculture focuses on environmental, economic, and social sustainability to improve capacity building and utilize land effectively for the aquaculture sector.

Aquaculture encompasses a wide range of different aquatic farming practices with regard to species (including seaweeds, mollusks, crustaceans, fish, and other aquatic species groups), environments, and systems utilized, with very distinct resource use patterns involved, offering a wide range of options for diversification of avenues for enhanced food production and income generation in many rural and peri-urban areas.

“In 2030, 90 per cent of all aquatic animal production will be for human consumption, an overall increase of 15 per cent compared with 2020.”

Key Challenges Faced by the Aquaculture Sector

Through time, the aquaculture sector has faced some problems, including the following,

  • By 2050, food consumption will be expected to increase from 2400 kcal/day to 3000 kcal/day.
  • The share of calories derived from cereals is declining in India.
  • There will be around 70 million undernourished people in India by 2050.
  • Over the years, freshwater resources have been shrinking.
  • Unavoidable intensification of aquaculture leads to environmental pollution, unprecedented disease occurrence, and heavy loss in the end.
  • Input costs for aquaculture are rapidly increasing.

Why is Sustainable Aquaculture the Ultimate Solution? 

Sustainable aquaculture is the need of the hour for several reasons.

Firstly, the global population is increasing at an alarming rate, and the demand for food is also increasing.

Aquaculture is a viable solution to meet this growing demand for food as it can produce fish and other seafood at a much faster rate than traditional fishing methods.

“According to FAO, nearly 870 million people out of 7.1 billion world population suffer from malnutrition.”

Graph of Regional Contribution To World Capture Fisheries and Aquaculture Production

Secondly, overfishing and pollution have severely depleted wild fish populations, making it necessary to rely on aquaculture to meet the demand for seafood.

Sustainable aquaculture practices can help preserve wild fish populations by reducing the pressure on them.

Thirdly, climate change is affecting the oceans and wild fish populations, making it necessary to have a sustainable and resilient food production system.

Aquaculture can help mitigate the effects of climate change by producing fish in controlled environments, reducing the dependence on wild fish populations that are affected by changing ocean conditions.

Finally, sustainable aquaculture practices can help preserve the biodiversity of the oceans and protect the habitats of wild fish populations.

It is important for the ecological balance of the oceans to ensure the long-term sustainability of seafood production.

Conclusion

Currently, worldwide, there are many components of the aquaculture system that need innovation to solve fishing culture orthodox practices that create problems, including water pollution, fish feed, disease prevention, and maximizing productivity sustainably.

Organica Biotech is one of the leading companies with advanced solutions that can unlock superior aquaculture with natural solutions.

Developed through many years of research, we have redefined the landscape of aquaculture sustainability via Bioflok, Bioclean Aqua Plus, Bioclean Aqua, and Biogut Aqua.

At Organica Biotech, we are revolutionizing aquaculture by deploying innovative research-backed solutions to boost fish immunity and nutrition and reduce the organic burden in the aquaculture ecosystem.

Benefits of Construction Site Portable Toilet Installation

Posted on by Priyanka Khaire

Portable Toilet
The construction industry is one of the largest employers in India, with over 50 million workers contributing to infrastructure development.

However, a critical challenge remains—access to proper sanitation.

A 2022 study by the National Sample Survey Office (NSSO) found that nearly 70% of construction sites lack adequate toilet facilities, forcing workers to resort to open defecation, which compromises hygiene, health, and dignity.

The lack of sanitation not only affects worker well-being but also leads to productivity losses and environmental concerns.

As the government intensifies its Swachh Bharat initiative, portable bio-toilets have emerged as a game-changing solution for the construction industry, offering affordability, convenience, and sustainability.

Portable toilets have the potential to revolutionize the sanitation and hygiene standards in the construction industry.

In India, workers typically spend 8 to 9 hours at construction sites, which are sometimes located at far-off places or on the outskirts of the city.

There are other concerns like open defecation practice, which is still prevalent.

It is also important to maintain cleanliness and promote hygiene among workers as part of the Swachh Bharat initiative by the government of India.

Toilets that are portable and easy to install help satisfy the basic sanitation needs of construction workers.

In the past many years, a considerable amount of research has been done to develop innovative sanitation solutions.

As a result, bio-toilets have emerged as a reliable and cost-effective portable sanitation solution that can help workers at construction sites.

There are several benefits of construction site portable toilet installation, which are discussed below.

Convenience

One of the major benefits of installing a portable toilet at construction sites is convenience.

Construction projects usually cover large areas of land, with workers engaged in different activities.

The portable toilets enable workers to attend nature’s call anytime, day or night, without hassles.

Accessibility is another important factor that encourages workers to use portable bio-toilets instead of practicing open defecation.

Also, portable toilets can be dismantled, shifted, and again assembled with minimum effort.

Productivity

Portable toilets available at the site can boost the productivity of the workers.

Having portable toilets nearby means shorter breaks and less time traveling from one place to another.

It also prevents prolonged disruption of the workflow, which is necessary to maintain momentum and achieve productivity goals.

Sanitation and Cleanliness

The Swachh Bharat initiative aims to provide better sanitation facilities for everyone.

At the same time, maintaining cleanliness and hygiene is more important than ever for good health today.

Portable toilets are helpful to maintain sanitation and cleanliness standards at construction sites.

Since they are self-contained, portable toilets do not need sewerage disposal.

They are not connected to the ground, septic tank, or pipes connected to treatment plants.

Thus, it improves sanitation and general cleanliness, and hundreds of workers are employed there.

Affordable

The construction projects generally have temporary offices and make-shift places to rest.

Therefore, building permanent toilets is expensive and does not have value in the long run.

Portable toilets are affordable and cost-effective means to achieve sanitation goals at construction sites.

Water

Water scarcity is a problem plaguing different parts of India.

If you are working on a remote project, the water supply can be cut off due to unforeseen circumstances or insufficient water available for basic needs.

In such cases, portable toilets which function based on biological treatment can be of great help.

Bio-toilets can help in saving water massively.

A bio-toilet consists of a digester tank that contains powerful microbes.

The bacteria breaks down and degrades the human waste in the tank and gives harmless by-products in the form of methane and water.

Thus, there is little use of water.

Bio-toilets are beneficial to protect the environment.

In common portable toilets, waste deposited in the tank needs to be removed manually.

The leakage during this process can pollute the construction site environment and disturb the aesthetics as well.

Moreover, it can have odour issues and blockages.

Bio-toilets have proper bio-digesters with robust microbial consortia, where human solid waste is degraded and converted into liquefied waste, which is further broken down into water, gases, and energy, thus controlling environmental pollution.

Portable bio-toilets made of strong and durable material are necessary because construction projects take a long time to complete.

Organica Biotech is one of the leading companies with innovative sanitation solutions and portable bio-toilets.

Bioclean Biotoilet is an advanced and sustainable toilet system that is easy to install.

It also helps decompose human waste without hassles.

Made from FRP (Fiber Reinforced Plastic), UPVC (Unplasticized Polyvinyl Chloride), PCC(Pre-Cast Concrete), and PPGI (Pre Painted Galvanised Iron), Bioclean Biotoilets are durable and do not require any maintenance.

It provides excellent insulation from rain, cold, heat, etc.

The unit consists of a superstructure, digester tank, and advanced microbial solution known as Bioclean BD, which works well even in harsh conditions and degrades waste.

Bioclean Biotoilet is the best construction site portable toilet, which can be used by the construction industry to provide the best sanitation facility to workers.

Impact of Algal Blooms on Aquaculture and Effective Solution

Posted on by Dr. Anuja Kenekar

Algal blooms are becoming a serious threat to aquatic ecosystems, fisheries, and human health.

Over the past 50 years, India has seen a steady rise in harmful algal blooms (HABs) driven by increasing pollution, agricultural runoff, and climate change.

Globally, these blooms are responsible for economic losses of nearly $8 billion per year, devastating fish populations and disrupting livelihoods.

Harmful algal blooms release toxins, deplete oxygen levels in water, and pose severe risks to aquatic life and public health.

From massive fish deaths in Mumbai’s coastal waters in 2018 to widespread shellfish poisoning in Maharashtra, Tamil Nadu, and Karnataka, the consequences of HABs in India are alarming.

Without intervention, these blooms will continue to degrade water bodies, impact food security, and threaten the sustainability of aquaculture.

Addressing this challenge requires urgent action.

Bioremediation using natural microbial solutions offers a powerful way to control algal growth and restore water quality.

Did you know an algal bloom can be defined as the excessive proliferation of naturally growing algae in an aquatic ecosystem?

The microscopic algae ‘Phytoplankton’ is the smallest living entity that performs photosynthetic activity and forms the base of the aquatic food chain.

However, a small subset of it is harmful, and it is the main cause of the algal bloom.

It is better known as harmful algal blooms – HAB, a term coined by the Intergovernmental Oceanographic Commission of UNESCO.

It clearly perceives HAB’s negative impact on fisheries, the economy, and public health as a major threat.

Aquaculture, one of the fastest-growing food sectors in the world, is facing huge challenges and risks due to harmful algal blooms.

It has been estimated that losses of approximately 8 billion dollars are incurred across the globe per year as it directly impacts coastal commodities and fish resources.

An algal bloom is not a new phenomenon, but its impact has been studied and understood only in the past century or so.

In India, harmful algal blooms have steadily increased in the last 50 years due to various factors.

Algal Bloom Causes

The major factors contributing to the algal bloom are:

  • Nutrients like phosphorus and nitrogen reach our natural water resources in many ways. Excessive use of fertilizers in agriculture leaks into the groundwater and meets the closest water body. Another major source is industrial waste, chemicals, and effluents, where the partially treated wastewater is let into surrounding water bodies or sewage systems, where it ultimately travels to the sea.
  • An algal bloom is generally observed where the water resources are still. For example, in ponds or where aquaculture is done in a limited space, the chances of algal bloom increase. A large amount of water with no disturbance causes a massive increase in algal growth.
  • According to scientists, increasing temperatures due to global warming have contributed to the growth of harmful algal blooms. The high temperatures break down nutrients in water bodies, which are then easily consumed by algae, causing them to proliferate excessively.

Effects of Harmful Algal Bloom

This increase and dense accumulation of the algal population leads to the deoxygenation of water and evokes the release of toxic compounds known as phycotoxins, which are harmful to aquatic living beings as well as to humans.

There are three main types of HAB microorganisms: non-toxin-producing, toxin-producing, and non-toxic to humans but toxic to the aquatic ecosystem.

The non-toxic producing species reduce the amount of dissolved oxygen in the water resources.

Due to the rapid growth of algal microorganisms, they consume more oxygen and proliferate continuously, thus increasing the competition for oxygen.

This eventually leads to fish kills.

In 2018, an algal bloom led to massive fish deaths in the Mumbai coastal areas.

Also, it leads to the discoloration of water and destroys its aesthetic look.

The non-toxic to humans but toxic to fishes are the ones that damage the gills of fish and thus suffocate and kill them.

The toxin-producing species kill the beneficial algae, which is important in the food chain as highly aquatic life forms consume them.

Many kinds of fish feed on the algae which humans eventually consume.

This can lead to serious health repercussions in the form of a stomach illness, neurological problems, paralysis, diarrhea, etc.

In India, several incidents have been reported in the past.

In the year 1981, many were hospitalized, and few died in places like Maharashtra, Tamil Nadu, and Karnataka due to shellfish poisoning caused by algal bloom.

In Kerala in 2004, more than 200 people suffered nausea and breathlessness due to the foul smell emanating from the algal bloom in the region of Kollam and Vizhinjam.

One of the best ways to limit algal bloom is to biologically remediate water bodies and bring down nitrogen and phosphorus levels in the water.

Bioclean Pond Clarifier from Organica Biotech is a tailormade natural and microbial solution created for the effective bioremediation of ponds.

It aggressively acts on organic pollutants and reduces the excessive load of nutrients in the water.

It is highly capable of controlling odour, and minimizing sludge volumes, thereby preventing algal growth.

A Peek into the History of Wastewater Treatment

Posted on by Priyanka Khaire

Sanitation facilities, toilets, and treatment solutions help treat the highly toxic substances present in wastewater.

It further prevents it from reaching precious water resources consumed by humans as well as other living beings.

However, the wastewater treatment process used today has evolved over many thousand years.

There was a time in human history when everything, along with waste, was treated holistically.

It was part of the process or mechanism intimately interconnected by nature.

As the years went by, humans populated the earth, production and commercial processes took shape, and dealing with a huge amount of waste became important.

As of 2022, approximately 40% of domestic wastewater is discharged without safe treatment, highlighting significant gaps in global wastewater management.

The global water and wastewater treatment industry is projected to grow from $323 billion in 2023 to $536 billion by 2030, reflecting a compound annual growth rate of 7.5%.

In the United States, the water treatment industry is anticipated to undergo significant changes between 2025 and 2030, driven by stricter regulations, technological advancements, sustainability initiatives, and infrastructure upgrades.

A sanitation facility was first discovered in Babylon around 4000 B.C.

Clay pipes, cesspits, and the use of water became prevalent during this period.

Moving further, around 3000 B.C., in the city of Mohenjo-Daro, the first buildings with toilets were found.

The water utilized for washing and bathing was directed through canals and connected to a sewage system.

This sewage wastewater was collected and disposed of into the Indus River.

However, systematic disposal of wastewater into rivers has not been seen yet.

Then came a leap in the development of sewage systems in the Roman Empire.

It is observed that hygiene became prominent, and much focus was given to this aspect.

Cloaca Maxima in Rome is one of the earliest sewage systems that was made to collect wastewater.

Also, during this period, all households were required to connect to the sewage system as per the decree.

The canal has a breadth of 3.2 m and a height of up to 4.2 m.

Water supply and water discharge became fundamental to various cities during this era.

Yet, the need for treatment or disinfection solutions remained absent.

In the medieval period, people completely disowned the advances made during the Roman era, and this created a lot of trouble for the countries in Europe.

The sanitation became a headache, and poor facilities and disposal processes threatened public health.

Ultimately, it led to epidemics like cholera and breeding grounds for rats, which killed 25% of the population of Europe.

By the 19th century, the Industrial Revolution led to the extensive use of chemicals for various processes.

The amount of water used in the process was enormous, and many regarded it as a tragedy for the environment, as water was used so extensively in Earth’s history never before.

The wastewater from production plants was contaminating drinking water wells due to poor infrastructure and causing diseases.

With advances in microbiology and the invention of the microscope by Antoni van Leeuwenhoek, many doctors like John Snow, Robert Koch, and Louis Pasture figured out that the harmful bacteria in the wastewater were causing the deadly disease of cholera and other illnesses.

The authorities, mainly in the United Kingdom and the USA, began to understand the need for wastewater treatment, and removing unwanted pollutants is a must before releasing them into the environment.

Thus, various studies were undertaken, and methods were developed to treat wastewater.

More stringent laws were passed for better waste disposal practices.

Gradually, households, industries, offices, and institutions started to have well-structured sanitation systems that carry the wastewater through underground pipes to the wastewater treatment plants.

The process mainly contained three stages, namely Primary Treatment, Secondary Treatment, and Tertiary Treatment, and it still exists.

  • In the primary treatment, large objects and solids are screened using filters and removed.
  • In the secondary treatment, more solid particles and organic matter present in the wastewater are removed using biological treatment. The harmful bacteria are removed in this stage, and it is during this process that 85 – 90 percent of pollutants are successfully removed.
  • In the tertiary process, disinfection or chlorination takes place to make the effluent good enough to be released or reused.

As mentioned before, the secondary treatment of wastewater is a significant part of the process.

It was in 1914 that a major breakthrough was achieved by Edward Arden and William Locket, who found the activated sludge process, which is a biological form of treatment still prevalent today.

In the activated sludge process, the sewage is aerated in a tank to remove the biological solids and the biochemical oxygen demand – BOD.

It increases the aerobic bacteria concentration by the sedimentation process.

It was further improvised and turned into a continuous process, and thereafter, the first technical scale-activated sludge plant was constructed in Sheffield, UK, in 1920.

A few years later, in 1926, the first large-scale plant was built in Germany.

The main parts of an activated sludge system are the primary clarifier, aeration tank, and secondary clarifier.

Since the 1920s, many types of active sludge reactors have been used.

With modern innovations and complex processes involved in industries as well as new chemicals used in households, it was important to develop systems that are powerful and treat the effluent as per the standards set by government authorities at different places.

The popular ones are plug flow, complete mix, and sequencing reactors, complete-mix activated sludge – CMAS, and Sequencing Batch Reactor – SBR.

With advances made in science, technology, electronics, and testing procedures, it has been found that there is an urgent need to remove nitrogen and phosphorus content from wastewater, and the latest developments are aimed at achieving this goal.

Therefore, while the activated sludge process remains the same, there is an immediate need for better solutions to the wastewater treatment problem.

Chemical-focused solutions are not popular because they are harmful to the environment and the workers working in sewage treatment plants.

Biological solutions that are safe and eco-friendly can be the best alternative and boost productivity in STPs.

Organic Biotech’s Cleanmaxx STP is an advanced formulation of microbes that are adaptable and aggressive and designed specifically for STPs.

It helps in the reduction of approximately 95% ammoniacal nitrogen and 85% removal of BOD in the treatment plants.

It is a safe and natural solution that will be a crucial factor in the future of the wastewater treatment process.

Aerobic and Anaerobic Treatment Technology for Treatment of Industrial Wastewater

Posted on by Karen Sam

Aerobic and anaerobic treatment are two major types of biological wastewater treatment methods that help decompose the organic waste present in the wastewater.

As of 2024, industries worldwide generate approximately 300 billion cubic meters of wastewater annually, with treatment becoming a critical environmental and economic challenge.

The primary difference between the two processes is the use of oxygen.

The microorganisms in aerobic systems perform their function in the presence of oxygen, whereas in anaerobic systems, the decomposition process is carried out by microbes in the absence of it.

Read on to find out more about aerobic and anaerobic treatment technologies, origins, differences, advantages and disadvantages, and much more.

Brief History of Aerobic and Anaerobic Treatment

Aerobic treatment of wastewater began to be used more than 100 years ago, back in the 1890s.

The trials were first conducted in the UK and then in the US.

An aerobic system based on the principle of the activated sludge process was first studied by scientists around 1914.

As for anaerobic wastewater treatment, the sludge digestion process came into existence at the end of the 19th century in the UK.

Around 1927, the first heated tank unit was established in Germany.

Today, both aerobic and anaerobic treatments have evolved, gained recognition, and are used for different purposes.

Aerobic and Anaerobic Treatment Differences

The selection of aerobic and anaerobic treatment of wastewater depends on a large number of factors, including wastewater parameters such as pH, temperature, dissolved oxygen, etc.

In addition, COD, BOD, treatment duration, effluent quality, microbe quantity, and energy required are also considered.

This is the reason several experts believe the combination of both the systems and technologies is very beneficial.

However, there are many differences between aerobic and anaerobic treatment.

In most cases, the aerobic treatment method is utilized for wastewater with COD less than 1000 mg/L and when oxygen is a necessity for successful treatment.

In the aerobic process, oxygen and biomass are used to decompose organic waste, which is turned into carbon dioxide and water.

Apart from decomposition, pollutants like nitrogen and phosphorus are also treated through nitrification and denitrification processes.

Anaerobic treatment is used for wastewater with a COD of more than 1000 mg/L, which means higher organic loading.

Also, organic matter is decomposed by microbes in the absence of oxygen and creates harmless by-products such as carbon dioxide, water, and methane.

Other differences include investment, energy consumption, and sludge yield, which are higher for aerobic treatment than for anaerobic treatment.

As for technologies, Activated Sludge Process (ASP), Trickling Filter, and Rotating Biological Contactor (RBC) are used for aerobic wastewater treatment.

Anaerobic Digestors (AD), Continuous Stirred Tank Reactors (CSTR), Sequencing Batch Reactors (SBR), and Up-flow Anaerobic Sludge Blanket (UASB) Reactors are utilized in anaerobic wastewater treatment.

Aerobic and Anaerobic Treatment Advantages & Disadvantages

Aerobic treatment has the advantage of less odour as no hydrogen sulphide or methane is produced.

Moreover, it has better nutrient removal efficiency than anaerobic treatment.

High energy consumption and maintenance costs are some of the disadvantages.

Plus, extra costs are incurred to remove undigested solid waste.

The anaerobic treatment produces methane or biogas, which is a major advantage as it can be used as a renewable source of energy.

In response, many governments are enforcing stricter wastewater discharge standards, with the EU aiming for a 100% treatment target by 2040.

Economic Implications and Future Trends

The industrial wastewater treatment market is projected to reach approximately $13.9 billion by the end of 2024, with an expected compound annual growth rate (CAGR) of 6.4%, reaching around $24.29 billion by 2033.

This growth is driven by the increasing adoption of advanced treatment technologies and the implementation of stricter environmental regulations.

In summary, aerobic and anaerobic treatment technologies have undergone significant advancements, enhancing their efficiency and sustainability.

With increasing global industrialization and stricter environmental policies, the demand for innovative wastewater treatment solutions will continue to grow in the coming years.

Effective Wastewater Treatment for Textile & Dye Industries

Posted on by Karen Sam

Did you know that 17-20% of industrial water pollution comes from the textile dyeing and finishing industries?

They are considered one of the largest wastewater producers because a large amount of water is required for various processes.

According to recent reports, the global textile industry uses around 79 billion cubic meters of water annually, and by 2030, this is expected to increase by 50%.

With the rise in fast fashion and increased textile production, untreated wastewater discharge remains a significant environmental concern.

The effluents the industry releases contain biodegradable and non-biodegradable contents that create environmental issues, affecting aquatic plants, animals, and human health.

There are natural, pocket-friendly treatment solutions to remove toxins from water before releasing it into the natural water body.

Recent studies indicate that modern wastewater treatment technologies can remove up to 90% of dye contaminants, yet nearly 80% of textile wastewater globally is still discharged untreated, particularly in developing countries.

But before getting into that, let’s understand the characteristics of the effluent present in wastewater from the textile industry.

Understanding the Characteristics of the Effluents

The textile industry is divided into three major sectors: Cotton, Woolen & Synthetic.

The divisions are made because industries that use different fibers consume different kinds of artificial dyes and chemicals, and follow different processes.

Some of the processes include pre-treatment, dyeing and printing, and finishing.

The primary pollutants are organic, including pulp pre-treatment, cotton gum, cellulose, hemicellulose, carcinogenic dyes, and other printing processes.

Studies show that 15–20% of dyes used in textile dyeing do not bind to fabrics and end up in wastewater, making wastewater treatment crucial to reducing water pollution.

The wastewater released by textile industries contains high levels of color, BOD, COD, salt, TSS, and TDs, which are most contaminated by toxic chemicals and dyes.

Hence, it is critically important to treat wastewater before releasing it to maintain a balance in the ecosystem.

Some of the effective ways to treat wastewater are:

  1. Physicochemical Method
  2. Chemical Method
  3. Biological Method

Physicochemical Method

This treatment is most commonly used to remove high levels of chroma and suspended substances.

The processes in the physicochemical method are:

  • Equalization and homogenization: Pre-treating the polluted wastewater is essential before it reaches the regulating tank. The process prevents materials such as lint, cottonseed shells, and slurry from settling at the bottom of the tank. The wastewater is mixed with air or mechanical mixing equipment.
  • Floatation: The second step in treating the wastewater is with the help of floatation. The process produces large amounts of microbubbles to form three substances: water, gas, and solids. Under the effect, the microbubbles adhere to the tiny fibers and are effectively removed from the wastewater.
  • Coagulation, flocculation, sedimentation: In this process, heterogeneous matters are removed with the help of mechanical separation. Dissolved matter cannot be adequately removed in this process, but can be removed with the help of biological or physical-chemical processes.

Chemical Method

In this treatment, chemicals are applied to help separate contaminants from water or neutralize/destroy the harmful effects of pollutants.

Currently, Fenton oxidation and ozone oxidation are often used in wastewater treatment:

  1. Fenton Reaction: The Fenton reaction is a commonly used chemical method for treating textile effluent, where decolorization is the primary concern. The oxidizing agent is the leading chemical, Hydrogen peroxide (H2O2), which activates the most potent existing oxidizing agent, the hydroxyl radical. The Fenton reaction is used as a pre-treatment.
  2. Ozone Oxidation: This treatment is effective and fast at decolorization; it can either inhibit or destroy the properties of residual surfactants and oxidize a portion of the COD. The process is suitable for improving the biodegradability of textile effluents, which contain many toxic and non-biodegradable components.
  3. Adsorption: One of the most commonly used physicochemical wastewater treatment methods is adsorption. The process can efficiently adsorb and remove pollutants from the filter surface.
  4. Membrane Separation Process: Membrane separation is the process of filtering using membrane micropores. The treatment is mainly used to treat dyeing wastewater via reverse osmosis, ultrafiltration, nanofiltration, and microfiltration.
    • Reverse osmosis: Reverse osmosis removes mineral salts, hydrolyzed reactive dyes, and chemical auxiliaries.
    • Nanofiltration: This process is applied to treat coloured effluents from the textile industry. The filtration process decreases concentration polarizing with highly concentrated and complex solutions.
    • Ultrafiltration: Ultrafiltration is the process of eliminating macromolecules and particles such as pollutants, but the process doesn’t eliminate the polluting substances.
    • Microfiltration: The process used to treat bath dyes, which contain pigment dyes. The treatment can be used as a pre-treatment for nanofiltration or reverse osmosis.

Biological Wastewater Treatment Method

Biological wastewater treatment effectively degrades the organic matter in effluent from organic dye industries.

Biological treatment methods are divided into aerobic and anaerobic processes.

  • Aerobic Biological Treatment

Aerobic biological treatment helps purify wastewater using aerobic and facultative bacteria.

The process has many benefits in reducing high COD/BOD in effluent waters containing high TDS.

Many aerobic solutions are available in the industry, but Organica Biotech offers an effective microbial solution for aerobic wastewater treatment, with microbes that can thrive in high TDS effluents.

After conducting years of research, we developed a revolutionary product, Cleanmaxx ANB, an effective biological aerobic wastewater treatment solution.

The bacterial strains in Cleanmaxx ANB are capable of rapid biomass development and can withstand fluctuations in wastewater quality.

It accelerates COD/BOD reduction, rapidly reduces the time required for effective aerobic wastewater treatment, and reduces energy spent in aeration & agitation, thereby cutting CAPEX/OPEX costs.

Where Does Sewage Go?

Posted on by Priyanka Khaire

As city dwellers in an increasingly urbanised and highly populated country, this is a critical question to ask.

When you run the flush in the toilet in your home or office, the waste material, water, toilet paper, and everything else in the toilet bowl is pushed down a pipe typically called the sewer.

From here, it either makes its way into a septic tank on the premises – either in the backyard or underground – or flows further out beyond the premises to join a larger sewerage pipe facility run by the municipality.

According to the UN, nearly 80% of global wastewater flows back into the environment untreated. In urban areas of developing countries, improper sewage disposal remains a growing challenge, affecting public health and water resources.

With the exception of large cities with sewage networks, sewage is managed by septic tanks on-premise, not only in the case of independent houses but also in societies and residential clusters.

All this waste makes its way through the drains into the septic tank, where dense matter settles at the bottom of the tank while liquid goes into the soak-away pit from where it percolates into the soil.

However, studies show that nearly 60% of septic systems fail due to improper maintenance, leading to groundwater contamination.

The sewer pipes running out of homes and offices also gather other kinds of waste along the way.

This could be wastewater from the kitchen – cooking, waste liquid food, as well as from washing utensils, gardening water, mud, and waste, soapy water and remnants from the bathrooms – from the shower area as well as from cleaning the bathrooms and/or washing clothes.

All of this forms what we typically call sewage, and it travels through a network of collection pipes that we call sewerage pipes.

In the case of septic tanks, scum buildup can sometimes clog the influent side of the tank, causing a sewage backup into the home and a foul smell.

The World Bank estimates that inadequate sanitation costs countries billions annually due to health impacts and environmental degradation.

The Role of Sewerage Pipes in Large Cities

The role of sewerage pipes in large cities is to collect and transport all the sewage from individual establishments – homes, workplaces, schools, buildings, parks, gardens – and all other civic establishments to larger sewerage pipes from where it makes a long journey to a treatment plant.

This is a complex network of pipe systems that run meticulously under and over the ground.

Some of the larger pipes can be as large as vehicles and transport an unimaginable volume of waste collected from huge spans of land and urban settlements.

According to a recent study, cities like New York process around 1.3 billion gallons of wastewater daily, while Mumbai generates over 2.7 billion liters per day, highlighting the scale of sewage treatment challenges.

What Happens at Sewage Treatment Plants?

Most towns and cities have sewage treatment plants, which are like massive processing units where the wastewater is treated, toxic materials are separated, and a return flow of water back into the system is set off.

Since sewage coming into a plant contains a lot of germs, bacteria, and toxic material, it has to be handled safely and efficiently so as to eliminate the possibility of people coming into contact with it.

The process of treating wastewater consists of – screening, aeration, sedimentation, and finally, disinfection.

This way, everything from solid waste, like things that may have been accidentally flushed, like coins, plastic, jewelry, etc, to nebulous biochemical waste, is removed from the water.

A large amount of chemicals are then pumped into the wastewater to clean it up, rid it of all these harmful bits, and disinfect it of as many germs as possible.

This is a long process that can take up to 7-10 days, sometimes before the water is ready to be released into the system again.

The treated water is then gradually, through another network of pipes, released back into local waterways such as rivers, streams, and, in coastal places, the ocean.

Treated water released into rivers also eventually makes its way into the oceans.

This is why it is crucial to examine what goes into our wastewater and know and understand where it goes once it leaves our homes.

This is why it’s time to start examining what we put in our cleaning products and how toxic the waste water we create is.

The health of our waterways, oceans, and all the living beings – plants, animals, and humans – coming into contact with these ecosystems depends on it.

Untreated water or water that is too riddled with chemical waste outside the scope of what can be safely managed by the treatment plant, when released back into local waterways, can cause water pollution.

Over the years, this not only affects the quality of the water itself but also the surrounding ecosystem.

This cycle begins right at the source – our homes.

Whether your waste goes into a septic tank or through a sewage system, what you put down your drain and then turn a blind eye to eventually impacts the health of our local waterworks and ecosystem.

Here are a few ways to be aware and conscious of your contribution to wastewater.

  1. Flush responsibly: Ensure that you are safely and responsibly disposing of waste in your home. It is not advisable to pour household products such as strong cleansers, beauty products, medicines, chemical paints, and gardening products down the drain in your home. These are better collected and batch disposed at the local household hazardous waste facility. Every locality ought to have one, and it’s well worth finding out where the facility closest to you is. Wastewater treatment facilities are designed to treat organic waste, and hazardous chemicals often go untouched and unprocessed right back into local waterways, where they can wreak havoc in the long run.
  2. Avoid clogging waterways: Material that could potentially clog pipes, like dense cooking fats, sanitary napkins, disposable diapers, condoms, and the like, are meant to go into the solid waste bins and not down the toilet. While they may be pushed through your immediate sewerage pipes, they could collect further downstream and cause huge blockages in septic tanks and sewerage pipe systems, which can cause breaks in the system or outflow of harmful and poisonous waste.
  3. Turn to natural cleaning agents: Household cleaning products, when mixed with water and then drained away from our homes, are one of the leading causes of hazardous chemicals being leeched into our environments. Examine what’s in your cleaning equipment and choose those that are natural and safe not just for use in your home but also for the environment.

ThinkSafe is our range of non-toxic, non-corrosive, ammonia, and chlorine-free biodegradable home cleaning products that have been developed with this in mind.

The line of products is made entirely from plant-based ingredients for a microbe-friendly, pH-balanced, and chemical-free solution to cleaning, built around the need to safeguard and restore the biology and ecology in the areas of use.
