​BactaServe Aerobic Bioculture for STP & ETP Wastewater Treatment

​BactaServe Aerobic is a microbial bioculture that improves biological oxidation in aerobic wastewater treatment systems. It accelerates BOD and COD reduction, enhances MLSS growth, and stabilizes treatment performance in STP and ETP plants, making it ideal for faster commissioning, shock load recovery, and consistent effluent quality.

BactaServe Aerobic - Product overview  

BactaServe Aerobic is a specialized aerobic microbial bioculture developed for biological wastewater treatment systems operating in oxygen-rich environments. The formulation contains selected bacteria capable of rapidly degrading organic pollutants present in municipal sewage and industrial effluent.
 

When introduced into aeration tanks or biological reactors, the microbial consortium enhances biological oxidation, organic matter degradation and biomass stability. This improves treatment efficiency and helps restore microbial activity in wastewater treatment plants experiencing declining performance.
 

BactaServe Aerobic is widely used in Sewage Treatment Plants (STP) and Effluent Treatment Plants (ETP) where stable biological activity is required to maintain consistent effluent quality.

Key Features of BactaServe Aerobic

BactaServe Aerobic improves biological treatment efficiency by strengthening microbial activity in aerobic wastewater reactors.

Key performance advantages include:

  • Effective performance in oxygen-rich treatment environments

  • Rapid increase in MLSS with higher MLVSS values

  • Strong biodegradation of organic pollutants

  • Improved stability of microbial biomass under fluctuating wastewater conditions

  • Support for nitrification and denitrification processes

  • Suppression of harmful microbial growth

  • Suitable for both municipal and industrial wastewater treatment systems

Benefits of BactaServe Aerobic

  • Faster Commissioning of Treatment Plants: BactaServe Aerobic helps accelerate the startup of new STP and ETP plants by quickly establishing active microbial populations.

  • Improved BOD and COD Removal: The microbial formulation enhances biological oxidation, resulting in higher removal efficiency of organic pollutants in wastewater.

  • Resistance to Shock Loads: Treatment plants often experience sudden increases in organic load or toxic influent. The microbial consortium helps maintain biological stability during such fluctuations.

  • Reduction in Foul Odour: Enhanced aerobic digestion reduces the formation of odorous compounds in aeration tanks and secondary treatment areas.

  • Lower Sludge Generation: Efficient degradation of organic matter reduces excess sludge production and improves sludge settling characteristics.

  • Improved Effluent Quality: Stable biological activity helps wastewater treatment plants consistently achieve regulatory discharge standards.

Compatible Treatment Systems

BactaServe Aerobic can be used in a wide range of biological wastewater treatment configurations.

Compatible systems include:

  • Sewage Treatment Plants (STP)

  • Effluent Treatment Plants (ETP)

  • Activated Sludge Process (ASP)

  • Sequential Batch Reactor (SBR)

  • Moving Bed Biofilm Reactor (MBBR)

  • Membrane Bioreactor (MBR)

  • Extended aeration systems

The product can be applied to existing treatment systems without requiring modification of aeration capacity or reactor infrastructure.

How it Works

BactaServe Aerobic works by introducing active aerobic bacteria capable of metabolizing organic pollutants in wastewater. When added to the aeration tank, the microorganisms begin consuming organic matter in the presence of dissolved oxygen. During this biological process, complex organic compounds are converted into carbon dioxide, water and biologically stable biomass.
 

As microbial populations increase, biological activity inside the reactor improves. This results in stronger sludge formation, improved settling in secondary clarifiers and more efficient removal of organic contaminants.

Over time, the treatment system becomes more stable, odour levels decrease and effluent quality improves consistently.

Dosage and Application

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

Preparation Method

1 kg BactaServe Aerobic should be mixed in 20 litres of clean feed water before application. For larger quantities, maintain the same ratio.

Example: 2 kg in 40 litres of water
 

The mixture should be stirred thoroughly before dosing into the aeration tank or biological reactor.
 

Application Guidelines

  • Higher dosage may be used during startup or system recovery

  • Maintenance dosing can be applied during steady operation

  • Adequate dissolved oxygen levels should be maintained

  • Avoid simultaneous dosing of chlorine or strong biocides
     

Actual dosage may vary depending on wastewater characteristics and plant operating conditions. Plant-specific recommendations are typically provided by Amalgam Biotech technical team.

Technical Performance Evidence for Bactaserve Aerobic

Field applications of BactaServe Aerobic in wastewater treatment plants show improvements in organic pollutant degradation, microbial stability and treatment efficiency. The microbial formulation supports stronger biological activity in aerobic reactors, helping wastewater treatment facilities maintain stable performance even under fluctuating influent conditions.

Organic Pollutant Degradation Performance

Across aerobic treatment stages in industrial ETPs and STPs, the use of BactaServe Aerobic has resulted in:

  • COD reduction improvement ranging from 85% to above 95% in stabilized aerobic systems, depending on influent characteristics

  • BOD reduction improvement typically exceeding 90% once active biomass is established

  • Faster attainment of steady state conditions after startup or shock loading events

  • In pharmaceutical and chemical wastewater applications, aerobic outlet COD values have been observed to reduce from above 3000 mg/L to below 500 mg/L after biological stabilization under controlled operating conditions.

Biomass Development and Health Indicators

One of the primary indicators of aerobic system health is the development of active biomass. Field observations indicate that BactaServe Aerobic supports:

  • Increase in MLSS concentrations from sub-optimal levels below 1000 mg/L to stable operating ranges between 3000 to 4500 mg/L

  • Improvement in MLVSS to MLSS ratio from below 40% to values exceeding 60%, indicating healthier and more active biomass

  • Improved sludge settleability, reflected through stable SV30 behavior and reduced biomass carryover

These changes directly contribute to consistent organic degradation and reduced system variability.

System Recovery and Stability Outcomes

In systems affected by shock loads, toxic influent, or biological stress, the application of BactaServe Aerobic has supported:

  • Restoration of aerobic conditions in tanks exhibiting grey or inactive biomass

  • Reduction in foaming and odour associated with incomplete aerobic oxidation

  • Improved dissolved oxygen utilization efficiency due to active microbial respiration

  • In multiple cases, visible improvement in aeration tank colour and biological activity has been observed within 10 to 20 days of controlled dosing and operational correction.
