Robust Microbial Formulation for Municipal Sewage Treatment

Rapid urbanisation has led to a massive burden on sewage treatment units around the world. Despite significant advancement in engineering processes for sewage treatment plants, enough importance has not been given to development of robust bacterial treatment systems for effective sewage secondary treatment.


Bioclean STP is a consortium of highly adaptable, fast growing, robust microbes that have the ability to degrade high organic loads owing to their high biomass generation capacity. This results in maximum BOD removal and minimum sludge production. Odour issues, often attributed to hydrogen sulphide production & ammonia in sewage treatment units, which cause nuisance to surrounding localities are prevented by Bioclean STP by complete and rapid degradation of organics. Sewage water often contain pathogenic loads that are a major health risk if left untreated. The microbes in Bioclean STP naturally compete with pathogens in sewage water and prevent their growth. Bioclean STP can be used in any sewage pumping station / treatment set up, with no hardware modification required.
Bioclean STP is a proprietary blend of numerous specially selected naturally occurring microbial strains which work synergistically to degrade complex organic matter in sewage. Bioclean STP minimises sludge volume and improves good floc formability, accelerating biomass settling. Incompletely degraded sewage results in the emission of foul odours resulting from ammonia and hydrogen sulphide production. Bioclean STP ensures complete degradation of organic matter, ensuring no production of hydrogen sulphide production & ammonia and preventing malodours. The microbes in Bioclean STP suppress pathogens prevalent in sewage waters and reduce health risks. Bioclean STP also stabilises the STP & helps it withstand shock loads.
1. Rapid organic waste degradation in aerobic composting process.
2. Curbs noxious odours from your compost pile
3. Repels pathogens and enhances beneficial microbial activity
1. Easy to apply, speeds up plant commissioning and provides 100% efficiency despite harsh weather conditions.
2. Accelerates organic matter degradation & minimises sludge production.
3. Significantly reduces fecal coliforms & provides complete odour control.
4. Does not require any hardware modifications, improves treatment rate, thereby reducing CAPEX and OPEX costs.
5. Improves STP resistance to shock loads, improves plant efficiency and STP stability.

We have been using Organica’s high-tech microbial product Bioclean for solving many critical problems in Vietnam related to industrial and municipal wastewater. Bioclean has always proved to be the best performing sewage water treatment product. Previously we have tried using various other sewage treatment products from US and Australia, but Bioclean has surpassed all of them regarding performance and cost-effectiveness. We have been able to lower the pollution parameters within the desired limits along with a reduction in odour and sludge generation to a great extent. Bioclean performs under all kind of environmental and design variations.


How does Bioclean work in biological wastewater treatment?

Bioclean’s mode of action essentially comprises two major steps in biological wastewater treatment. The initial step involves the breakdown of complex compounds into simple polymers. These polymers are further degraded to form carbon dioxide and water which lowers the cumulated sludge yield and also ensures odor control. This subsequently results in optimization of effluent parameters (COD, BOD, TSS, NH4-N, TN, TP), that are considerably brought down below the mandatory limits.

Is Bioclean safe to handle?

Microbes present in Bioclean are GRAS organisms (Generally Recognised As Safe). These are completely safe without any pathogenicity towards humans, animals, and plants.

Can energy consumption be achieved using this technology?

The robust bacterial formulation in Bioclean contain membrane structures which facilitates the transportation of the dissolved Oxygen molecule and considerably reduce the aeration requirement of the system. In addition, since these strains are more competitive than the naturally growing heterotrophs in the competition for food due to their higher metabolic rate, we are able to accelerate the metabolism of organic matter in the bioreactors. As a result massive energy cost savings for the operator is delivered.

What type of pollutants can be treated using Bioclean in the secondary treatment of wastewater?

A major portion of all man-made and natural contaminants can be effectively degraded by Bioclean.

Can microbes in Bioclean perform under high TDS levels?

Conventional bacteria are subjected to cell lysis in the presence of aggregated volumes of Total Dissolved Salts (TDS). Bioclean consists of specialized strains of halophiles that survive and perform under high TDS levels.

What is the dosage of Bioclean?

Dosage of Bioclean is highly dependent on parameters like hydraulic and organic load, plant design, etc. Generally, the dosage varies from 0.1 ppm to 5 ppm depending upon the conditions in the Wastewater Treatment Plant.

Is Bioclean in powdered form or liquid?

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

How is Bioclean Superior to other products available in the market?

Bioclean 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.

Where can Bioclean be applied?

  • Activated Sludge
  • MBBR
  • MBR
  • SBR
  • Rotating Biological Contactors
  • Extended Aeration
  • Fluidized Bed Air Reactor
  • Trickling Filter & other Aerobic reactors

Can the commissioning/stabilization period of aerobic reactor be reduces with the aid of Bioclean?

The varied nature of the microbes present in Bioclean enables faster degradation of complex pollutants and enhanced biomass generation. This facilitates faster commissioning of bioreactors and restores the stability of the same.

Benefits of Waterless Bio-Toilet – A Sustainable Sanitation Solution

Plenty of people probably use toilets multiple times in a day. A large amount of precious water is flushed down the drain turning it into waste. According to a statistic provided by Conserve H2O, a Water Providers Consortium, 1.6 litres of water is wasted per flush. Depending on the toilet cistern parts, toilets can use even more water.

A home flush system uses up to 12 litres of water per minute. Plumbing experts say that in commercial buildings, 45 litres of water is utilized per day per employee. The huge amount of water wasted can be treated for drinking.
