How does Cleanmaxx® STP work?

Cleanmaxx® STP mode of action essentially comprises two major steps. The initial step involves the breakdown of complex compounds into simple polymers. These polymers are further degraded to form carbon dioxide and water. The microbes in sewage treatment perform these functions.

Are the bacteria present in Cleanmaxx® STP genetically modified?

The microbes present in our sewage treatment solution are not genetically modified. These are natural isolates that are specially selected for their desirable traits. The microbes in sewage treatment are found to be effective.

Is Cleanmaxx® STP safe?

Microbes present in Cleanmaxx® STP are GRAS organisms (Generally Recognised As Safe). These are completely safe without any pathogenicity towards humans, animals, and plants. The microbes in sewage treatment effectively degrade waste.

What type of pollutants can be treated by using Cleanmaxx® STP?

A major portion of all man-made and natural contaminants present in municipal wastewater can be effectively degraded by Cleanmaxx® STP.

What is the dosage of Cleanmaxx® STP?

The dosage of Cleanmaxx® STP is highly dependent on parameters like hydraulic and organic load, plant design, etc. Generally, the dosage of microbes in sewage treatment varies from 0.1 ppm to 5 ppm depending upon the conditions in the sewage treatment plants.

Is Cleanmaxx® STP a powder or liquid?

Microbes in Cleanmaxx® STP are microencapsulated in powder form. This confers the virtue of extended shelf life to the product.

How is Cleanmaxx® STP superior to the other products available in the market?

Cleanmaxx® STP is a well-curated product consisting of a robust blend of microbes that can effectively degrade diverse pollutants into simple compounds.

Each microbe is isolated from its natural habitat and cultured in our facility. Our cutting-edge technology ensures that these bacteria remain in a dormant state and have a 95-98% reactivation state within their shelf life of two years.

Can microbes in Cleanmaxx® STP perform under shock loads?

Conventional bacteria are subjected to cell death in the presence of stress conditions like Hydraulic shock load & Organic Shock load. Cleanmaxx® STP, which consists of specialized strains of microbes in sewage treatment, survives and performs under shock loads.

Can the commissioning/stabilization period of Sewage water treatment plants be reduced with the aid of Cleanmaxx® STP?

The varied nature of the microbes present in Cleanmaxx® STP enables faster degradation of complex pollutants and enhanced biomass generation. This facilitates faster commissioning of sewage water treatment plants and restores stability of the same.

What are the steps for sewage treatment?

A sewage treatment process generally involves 3 steps. First is the primary step, where solids, grit, oil, and grease are physically separated out.

The second one is the biological step, where the beneficial microbes in the sewage treatment plant degrade the dissolved pollutants present in it.

The third stage is the disinfection stage, where the harmful biological load from the treated water is reduced by chlorination, U.V., or ozonation, after which the water is discharged into fresh water.

How is sewage treatment different from effluent wastewater treatment?

The water entering a sewage treatment plant majorly consists of wastewater from households, offices, and a small amount of industrial wastewater.

Most effluent treatment systems deal with wastewater from an industrial process that is relatively very high in organic loading, along with various chemical compounds that are tough to treat.

Due to the high volumes of water it contains, sewage water treatment becomes a challenge for treatment at a rapid pace. Industrial wastewater, on the other hand, is concentrated with organic and inorganic pollutants and, therefore, is difficult to treat on most occasions due to these high concentrations.

This is why the general population of microbes in sewage treatment differs from those present in effluent wastewater treatment plants.

The sewage water already contains a high microbial load, so why do we require the addition of microbes in sewage treatment?

Yes, the sewage water does contain its own microflora. However, often enough, these microbes do not have the capability to effectively degrade the vast spectrum of pollutants that contribute to the organic load in sewage water.

Not just this, they could be pathogenic in nature as well. Microbes in sewage treatment require to be versatile, tenacious, and capable of adapting to shock loads as well.

The addition of specially selected microbes in sewage waste water treatment, like those present in Cleanmaxx STP, helps improve the efficiency of sewage water treatment by accelerated degradation of a variety of organic pollutants present in it.

Does primary sewage treatment require adjustment of pH?

The pH of the sewage water is mostly near neutral due to the high volumes of water; hence, primary sewage water treatment does not require pH adjustment.

However, there must be continuous online pH monitoring of incoming untreated sewage water during secondary treatment, which ensures that the microbes in sewage treatment do not fail due to extreme fluctuations in pH.

Can we obtain pathogen reduction from sewage water treatment by Cleanmaxx STP?

Cleanmaxx STP contains a consortium of fast-growing bacteria that compete with the pathogens for food, reducing the food availability for pathogens. They also produce metabolites that are inhibitory to pathogens.

The microbes in sewage treatment help reduce the pathogen load through a scientific principle called “competitive exclusion” when Cleanmaxx STP is used.

What are the most commonly used secondary treatment technologies for sewage treatment?

The basic technologies used for secondary sewage water treatment are suspended-growth and attached-growth systems. A suspended growth system in a sewage water treatment consists of an activated sludge process, sequential batch reactor, and many more where free-floating microorganisms move along the wastewater, degrading the pollutants.

In attached growth systems used in sewage water treatment like trickling filters, rotating drum contractors, MBR, and many more, which require the use of media on which microbes attach themselves and form a biofilm that effectively degrades the sewage water passing through it.

Can the detergent and soap water be treated by microbes in sewage treatment?

Yes, soap water, and detergent can be treated by microbes in sewage treatment. The soap contains organic compounds like fatty acids and oils, which can undergo complete biodegradation by specially selected bacteria.

If not subjected to sewage treatment, they can lead to scum formation and disturb the natural microflora and dissolved oxygen levels of the sewage water. Comparatively, detergents are recalcitrant in nature, but ammonia, phosphorus, and phenol compounds in detergents can be treated by specialized bacteria available in Cleanmaxx STP.

Does the addition of water from a swimming pool affect microbes in sewage due to the presence of chlorine?

Chlorine is known for its antimicrobial activity. The concentration of chlorine in the swimming pool is maintained at 1 to 2 mg/L.

When the water from the pool gets mixed with the sewage water and reaches the municipal wastewater treatment plant, the chlorine is diluted manifold; such a low concentration of chlorine is not able to impact microbial action in sewage water treatment.

Why does the sewage water look blackish in my sewage water treatment plant?

The main reason for sewage water becoming blackish in color is due to the depleted amount of dissolved oxygen in the sewage treatment tank.

The dark brown or black color is due to the reaction of sulphides with metals in sewage water under anaerobic conditions. It could be rectified by increasing the dissolved oxygen levels in the biological tank.

Why is there a rotten egg-like odour in my sewage water treatment plant?

The foul odour, like rotten eggs in sewage water treatment plants, is mostly due to the formation of hydrogen sulfide gas in the tank. Hydrogen sulfide gas formation starts as the dissolved oxygen in the tank reduces, giving rise to anaerobic conditions inside the tank.

How do we manage the excessive sludge after sewage treatment?

Post the function of microbes in sewage treatment completes, the excess of sludge is removed from the secondary clarifier through the pipes and carried to a sludge holding tank for the dewatering process.

The dewatering process is carried out by centrifugation or filter press. This sludge is later disposed of or used as fertilizer after appropriate treatment.

Why is disinfection required for secondary treated water in sewage water treatment plants?

Sewage water treatment is extremely essential because sewage water inherently contains a high amount of pathogens and disease-causing microorganisms, which, when released into the natural water bodies, can create health hazards for others.

Hence it is advisable to disinfect water at the final stage of sewage water treatment before disposing of out into any kind of water body.
