BactaServe STP Bioculture for Sewage Treatment Plants

BactaServe STP is a microbial bioculture that improves biological treatment efficiency in sewage treatment plants. It enhances BOD and COD removal, increases MLSS with higher MLVSS content, and stabilizes biological performance, making it ideal for municipal, residential, commercial, and institutional STP systems requiring reliable wastewater treatment.

BactaServe STP - Product overview  

BactaServe STP is a specialized microbial bioculture developed for sewage treatment plants (STP) operating under aerobic biological treatment conditions. The formulation contains selected microorganisms capable of rapidly degrading organic pollutants present in domestic sewage and municipal wastewater.
 

When introduced into biological treatment stages, the microbial consortium supports biological oxidation, organic load degradation and active biomass development. This improves treatment efficiency and helps stabilize biological processes in sewage treatment systems.
 

BactaServe STP is widely used in municipal sewage treatment plants, residential STP systems, commercial wastewater treatment facilities and institutional sewage treatment systems where consistent biological performance and regulatory compliance are required.

Key Features of BactaServe STP

BactaServe STP improves biological treatment efficiency in sewage treatment plants by strengthening microbial activity in aerobic reactors.

Key advantages include:

  • Improved COD and BOD degradation efficiency

  • Reduced commissioning time of sewage treatment plants

  • Rapid increase in MLSS with high MLVSS content

  • Suppression of harmful bacterial growth

  • Reduction in overall operational cost

  • Reduced sludge generation in treatment systems

  • Shock load stabilization in sewage treatment processes

  • Powder formulation that is easy to store and apply

Benefits of BactaServe STP

  • Faster Commissioning of STP Systems: BactaServe STP helps accelerate biological stabilization in new sewage treatment plants, allowing systems to achieve steady operation faster.

  • Improved Organic Pollutant Removal: The microbial formulation enhances biological oxidation processes, resulting in improved removal of COD, BOD and organic pollutants.

  • Stable Biomass Development: Rapid growth of active biomass improves MLSS concentration and strengthens biological treatment efficiency.

  • Reduced Sludge Generation: Efficient organic degradation reduces excess sludge formation, lowering sludge handling and disposal requirements.

  • Lower Operational Cost: Improved biological treatment efficiency helps reduce energy usage, chemical dosing and maintenance requirements.

  • Shock Load Stabilization: The microbial culture helps treatment systems remain stable during sudden increases in organic loading.

Compatible Treatment Systems

BactaServe STP can be integrated into multiple sewage treatment configurations.

Compatible systems include:

  • ASP – Activated Sludge Process

  • E-ASP – Extended Aeration Process

  • SBR – Sequencing Batch Reactor

  • MBBR – Moving Bed Bio Reactor

  • MBR – Membrane Bio Reactor

These biological processes rely on active microbial populations to degrade organic pollutants in sewage.

How it Works

BactaServe STP works by introducing active microbial cultures that enhance biological degradation of organic pollutants in sewage. When the culture is added to aeration tanks or biological reactors, microorganisms consume organic waste in the presence of dissolved oxygen. Through microbial metabolism, organic matter is converted into carbon dioxide, water and stable biomass.
 

As microbial populations grow, the biological treatment system becomes more efficient. This improves sludge formation, enhances settling characteristics and increases the overall treatment performance of the sewage treatment plant.

Dosage and Application

The dosage of BactaServe STP depends on wastewater volume, organic loading and operating conditions of the treatment plant.

Preparation Method

Mix 1 kg BactaServe STP in 20 litres of feed water before dosing.

Example: 2 kg in 40 litres of feed water.

The mixture should be stirred thoroughly before application.
 

Application Guidelines

  • Mix the culture thoroughly before dosing

  • Apply according to the recommended dosing schedule

  • Quantity required depends on wastewater volume and organic load

  • Maintain adequate aeration during application

Actual dosage may vary depending on plant design and operating conditions.

Technical Performance Evidence for Bactaserve STP

BactaServe STP bioculture has been applied in municipal and institutional sewage treatment plants where inconsistent organic removal, poor biomass health, odour issues, and unstable biological performance are common. Field applications demonstrate reliable COD and BOD reduction, improved biomass development, and faster system stabilization.

Organic Load Reduction Performance

Across multiple STP applications, BactaServe STP has resulted in:

  • Consistent reduction of COD and BOD to discharge compliant levels

  • Improved handling of shock hydraulic and organic loads

  • Reduced variability in outlet quality

  • Improved performance during seasonal load fluctuations

These improvements support reliable long term STP operation.

Biomass Development and Process Stability

Field observations indicate that BactaServe STP supports:

  • Faster development of healthy aerobic biomass

  • Improved oxygen uptake efficiency due to active microbial population

  • Reduced sludge bulking and biomass washout

  • Improved sludge settleability and secondary clarification

Healthy biomass is critical for stable municipal sewage treatment

Odour Reduction and Operational Outcomes

In STPs affected by odour and septic conditions, BactaServe STP has supported:

  • Elimination of foul odours from aeration tanks and channels

  • Reduction in anaerobic pockets within biological reactors

  • Improved working conditions around the STP

  • Visible improvement in system stability within 10 to 20 days

Compatibility with Existing Infrastructure

BactaServe STP can be implemented without modification to existing infrastructure. Performance improvements are achieved using:

  • Existing aeration capacity

  • Standard sludge recycling and wasting practices

  • No additional chemical dosing

This makes it suitable for both corrective intervention and performance optimization.
