Supporting Biological Treatment of Dairy Wastewater

Dairy processing generates wastewater containing organic matter from milk residues, lactose and other production-related materials. High BOD and COD, suspended solids, volatile fatty acids and ammoniacal nitrogen can create challenges for biological treatment systems.


BactaServe Dairy is a specialised microbial formulation designed for dairy wastewater treatment. It supports lactose degradation, helps manage high organic loads and volatile fatty acids, and promotes biological processes involved in anaerobic digestion and biogas generation.

Key Benefits of BactaServe Dairy

BactaServe Dairy supports biological treatment processes for wastewater generated by dairy operations.


  • BOD and COD Reduction: Supports the biological breakdown of organic matter in dairy wastewater.

  • Lactose Degradation: Helps degrade lactose, an organic compound present in dairy processing wastewater.

  • TDS and TSS Management: Helps manage high total dissolved solids (TDS) and total suspended solids (TSS) in the treatment process.

  • Volatile Fatty Acid Control: Supports the management of elevated volatile fatty acids during biological treatment.

  • Odour Control: Helps reduce unpleasant odours associated with biological wastewater treatment systems.

  • Ammoniacal Nitrogen Management: Helps control elevated ammoniacal nitrogen in dairy wastewater.

  • Enhanced Anaerobic Digestion: Supports acetogenesis and methanogenesis, the biological processes involved in anaerobic digestion.

  • Improved Biogas Generation: Helps improve the efficiency of biogas generation in suitable anaerobic systems.

  • Reduced Excess Sludge: Supports biological treatment with lower excess sludge production.

How BactaServe Dairy Works

Dairy wastewater contains biodegradable organic compounds, including lactose, that can contribute to high BOD and COD. During anaerobic treatment, microorganisms break down organic matter through a series of biological processes.


BactaServe Dairy supports the degradation of lactose and other suitable organic compounds while helping manage volatile fatty acids and ammoniacal nitrogen. Its application also supports acetogenesis and methanogenesis, which contribute to the conversion of organic matter during anaerobic digestion.


By supporting these biological processes, BactaServe Dairy helps improve treatment performance and biogas generation efficiency in suitable systems.

Applications of BactaServe Dairy

BactaServe Dairy is intended for biological treatment of dairy industry wastewater, particularly in systems using anaerobic processes.


  • Dairy Processing Wastewater: Supports the treatment of wastewater generated during dairy production and processing.

  • High-Organic-Load Wastewater: Helps address wastewater with elevated BOD and COD associated with biodegradable dairy residues.

  • Wastewater with Lactose: Supports the biological degradation of lactose in dairy effluent.

  • Anaerobic Treatment Systems: Supports biological activity in processes treating dairy wastewater under anaerobic conditions.

  • Biogas Generation Systems: Helps support the biological processes involved in anaerobic digestion and biogas production.

Suitable Wastewater Treatment Systems

BactaServe Dairy is suitable for consideration in the following anaerobic treatment configurations:


  • Upflow Anaerobic Sludge Blanket (UASB): For anaerobic treatment of suitable dairy wastewater containing biodegradable organic matter.

  • Anaerobic Digesters: For biological degradation of organic matter and support for biogas generation.

  • Anaerobic Fixed Film Reactors: For anaerobic treatment systems that use attached-growth microbial communities to process wastewater.

Dosage and Application Procedure

BactaServe Dairy is prepared by mixing the product with feed water before dosing. The required daily quantity depends on wastewater volume and organic load.


  • Preparation Ratio: Mix 1 kg of BactaServe Dairy in 20 litres of feed water. For larger quantities, mix 2 kg in 40 litres of feed water.

  • Mixing: Mix the product thoroughly with the feed water.

  • Application: Dose the prepared mixture according to the detailed dosage schedule for the treatment system.

  • Daily Quantity: Determine the required amount based on wastewater volume and organic load.

Important Application Considerations

Dairy wastewater characteristics can vary according to processing operations, cleaning practices and production schedules. These variations should be considered when applying a microbial formulation.


  • Organic loading: Assess BOD, COD and the quantity of biodegradable organic matter entering the treatment system.

  • Lactose content: Consider the organic load associated with milk residues and lactose-containing wastewater.

  • Volatile fatty acids: Monitor their accumulation in anaerobic systems as part of process performance assessment.

  • Ammoniacal nitrogen: Evaluate nitrogen levels where they are relevant to treatment performance.

  • Anaerobic process conditions: Consider the operating conditions of the UASB, digester or fixed film reactor.

  • Dosage requirements: Determine the daily quantity based on wastewater volume and organic load.


Monitoring relevant wastewater and process parameters helps assess biological treatment performance and identify operational changes that may require attention.
