Advanced Wastewater Management Technologies For Reduction Of Pollutants In Wastewater

With the increasing use of advanced technologies for wastewater management and testing, scientists have identified many different types of pollutants that can drastically impact human health and the environment.

Moreover, poor effluent quality may not meet standards and regulations established by authorities.

Thus, advanced wastewater treatment technologies are required to reduce suspended solids, BOD, nutrients, and toxins and remove pollutants in wastewater generated at domestic, industrial, and agricultural fields.

The main objectives of using advanced wastewater treatment technologies, besides the removal of pollutants in wastewater, include non-toxic but eco-friendly processes and environmental protection.

• Also, it involves innovative wastewater treatment solutions for economical and sustainable wastewater treatment.

Use of Advanced Wastewater Treatment Technologies

Various wastewater treatment technologies and processes are used in conventional wastewater plants to remove undesirable components from wastewater.

It includes primary, secondary, and tertiary treatment processes, which utilize physical, biological, and chemical removal of pollutants in wastewater, respectively.

Primarily, wastewater solutions are required to treat the effluent and release the same into the environment safely.

Furthermore, wastewater management should ensure that the effluent can also be used for different purposes, such as irrigation and industrial processes and sometimes for drinking.

However, due to population explosion, industrialization, and urbanization, there is a significant increase in wastewater generation, which is putting undue stress on existing wastewater treatment technologies and plants.

Also, the government and local authorities have made stringent regulations for effluent quality to protect the environment.

This is where advanced wastewater treatment technologies, either as a single unit or in combination with existing systems, can help boost wastewater management.

Membrane Bio-Reactor Technology – MBR

Membrane Bio-Reactor Technology, or MBR, combines the traditional activated sludge treatment process with the filtration process.

In this system, a membrane acts as a barrier that helps in sludge separation and retains all particle types and microbes, achieving superior wastewater treatment objectives.

An immersed process configuration of biomass rejection in MBRs is generally used as it is less expensive and uses less energy.

It is an effective modern wastewater treatment technology.

Moving Bed Biological Reactor – MBBR

Moving Bed Biological Reactor or MBBR is a high-performance and widely used biological treatment process that combines the activated sludge process and bio-filtration process.

This wastewater solution is a very effective industrial wastewater treatment method.

The main feature of MBR is that it has a continuously moving biological reactor where biomass growth occurs on plastic carrier elements with higher density than water.

The aeration system enables continuous movement.

Sequencing Batch Reactors – SBR

Sequencing Batch Reactors are similar to the activated sludge process in many aspects.

However, unlike ASP, where multiple basins are used, the SBR system uses a single basin for all treatment steps such as filling of wastewater in the basin, react phase with mixing and aeration, settling of activated sludge, decantation process and wasting where a small amount of activated sludge is removed.

Other than advanced wastewater management technologies, there are innovative and effective biological wastewater solutions that help in removing pollutants in wastewater.

Bioremediation is one such process where living microbes are used to degrade contaminants and pollutants in wastewater.

It is a highly effective as well as affordable solution. Organica Biotech is a leading company that has developed a wide range of solutions for wastewater treatment.

Cleanmaxx, which contains a consortium of special microbes, helps in the degradation of organic waste and sludge volume reduction, effectively boosting the performance of wastewater treatment plants.

Economical Wastewater Solutions For Effective Wastewater Management

Wastewater management is one of the biggest challenges facing the world today.

The main sources of wastewater include homes, offices, manufacturing industries, factories, agricultural activities, hospitals, etc.

When released untreated, toxic substances present in wastewater can potentially cause water pollution, disturb the environment, and pose health risks to the human population.

Therefore, effective wastewater treatment technologies and innovative wastewater solutions are urgently required.

Moreover, it is important to consider economical wastewater solutions as it is a prerequisite to attain wastewater management and treatment efficiency in most regions in India.

The conventional wastewater solutions, which include physical, biological, and chemical treatment processes, are expensive with no significant returns.

The complexities involved in daily operations such as handling, treatment, sludge removal, and high maintenance requirements reflect the inefficacy of treatment plants.

It often leads to process breakdowns, leading to failure and closure of plants.

Lack of high-performance wastewater treatment technologies means the effluent quality is compromised and does not meet the standards or comply with regulations.

Consequently, untreated wastewater reaches the environment and causes pollution.

Thus, existing wastewater solutions, treatment plants, and technologies that are neither cost-effective nor give economic returns need innovation and approach.

Modern wastewater treatment technologies, advanced biological wastewater solutions, and sustainable costs can help.

Experts also believe that decentralized treatment can be effective.

This means that local treatment systems covering a single or group of households and generating small volumes of wastewater can drastically reduce operating costs.

However, several factors need to be considered to determine the type of treatment systems to be used, which include climate, amount of waste generated, operation requirements, and social and economic conditions of the region.

Common Technologies used today to treat and remove pollutants in wastewater are as follows :

Membrane Bio-Reactors

MBRs uses biological membrane filtration processes which help in the degradation of pollutants in wastewater, effectively removing contaminants and organic matter.

According to different research and studies, MBR can result in a non-detectable amount of TSS, lower than 2mg/L of BOD and 0.5mg/L of ammonia concentration.

The filtration system eliminates the need for gravity clarification of the effluent.

Although it requires high maintenance, they are a highly efficient domestic wastewater treatment technology.

UASB

Upflow Anaerobic Sludge Blankets or UASB are popular and high-performance anaerobic digesters for wastewater treatment.

It has 75% COD removal efficiencies, low operational costs, energy recovering technology, low initial investment, easy maintenance, and minimum energy requirement compared to other anaerobic processes.

To make wastewater treatment more cost-effective, reducing energy consumption and maximizing efficiency can also benefit.

And there are many ways in which this objective can be achieved.

Aeration

The aeration system used in the activated sludge process in wastewater treatment utilizes close to 50% of the electricity used every year.

There are many ways you can optimize the aeration system.

Upgrading air distribution systems, dissolved oxygen control systems, and efficient blowers can reduce electricity consumption.

Sludge Management

Handling, pumping, and disposal of sludge account for a lot of energy in wastewater treatment plants.

Minimizing sludge volume using biological solutions is a great option to save money as well as energy.

Furthermore, biogas production can help generate electricity, heat, etc.

Microbial Cultures for Biological Treatment

Biological treatment has emerged as an eco-friendly and economical option, which has advantageous phenomenons of ‘bioremediation’ and ‘bio-augmentation.’

Both processes help in overcoming high COD/BOD levels caused due to specific and dominant pollutants in wastewater treatment systems.

Bio-augmentation is a high-potential economical wastewater solution for effective wastewater management of pollutants.

The environment-friendly approach augurs well for the future of wastewater treatment as well. Organica Biotech is one of the leading companies with efficient solutions for wastewater management.
