Supporting High-Rate Anaerobic Wastewater Treatment

High-strength industrial wastewater can place substantial demands on anaerobic treatment systems. Maintaining sufficient active biomass, efficient organic matter degradation and stable reactor performance is important for achieving effective treatment and biogas production.


BactaServe Anaerobic Granular Catalyst is a high-density biomass product developed for advanced anaerobic wastewater treatment. It supports accelerated system start-up, volatile fatty acid (VFA) conversion, biomass retention and methane generation in high-rate anaerobic reactors.

Key Benefits of BactaServe Anaerobic Granular Catalyst

BactaServe Anaerobic Granular Catalyst supports biomass retention and operational performance in anaerobic wastewater treatment systems.


  • Accelerated Start-Up and Commissioning: Helps accelerate the establishment of anaerobic treatment systems.

  • Enhanced VFA Conversion: Supports the conversion of volatile fatty acids during anaerobic treatment.

  • Improved Biomass Retention: Helps retain biomass within the reactor to support biological treatment.

  • Increased Methane and Biogas Yield: Supports methane production and biogas yield in suitable anaerobic systems.

  • BOD and COD Reduction: Supports organic matter degradation and the reduction of biochemical oxygen demand (BOD) and chemical oxygen demand (COD).

  • Process Stability Under Shock Loads: Helps maintain process stability during hydraulic and organic loading variations.

  • High Settleability: Supports biomass settling to help prevent washout and facilitate system recovery.

How BactaServe Anaerobic Granular Catalyst Works

High-rate anaerobic reactors depend on retaining active biomass while converting organic matter into simpler compounds and biogas. Biomass washout, variations in organic loading and hydraulic shock loads can affect reactor performance.


BactaServe Anaerobic Granular Catalyst provides high-density biomass for anaerobic treatment systems. It supports biomass retention and settleability while promoting VFA conversion and the biological processes involved in methane generation.


By supporting these functions, the product helps accelerate reactor start-up, improve organic matter degradation and maintain process stability under changing loading conditions.

Applications of BactaServe Anaerobic Granular Catalyst

BactaServe Anaerobic Granular Catalyst is designed for high-rate anaerobic treatment and industrial wastewater applications.


  • High-Strength Industrial Wastewater: Supports anaerobic treatment of industrial effluent with high organic loads.

  • New Anaerobic Reactors: Helps accelerate biological start-up and commissioning.

  • Biogas Production Systems: Supports methane generation and biogas yield during anaerobic digestion.

  • Reactors Experiencing Biomass Washout: Supports biomass retention and settling in suitable reactor configurations.

  • Systems with Hydraulic or Organic Shock Loads: Helps maintain process stability when loading conditions fluctuate.

Suitable Anaerobic Treatment Systems

BactaServe Anaerobic Granular Catalyst is suitable for the following reactor configurations:

  • Upflow Anaerobic Sludge Blanket (UASB) Reactors: For high-rate anaerobic treatment using a retained sludge blanket.

  • Expanded Granular Sludge Bed (EGSB) Systems: For anaerobic treatment using granular biomass under expanded-bed conditions.

  • Internal Circulation (IC) Reactors: For high-rate anaerobic treatment with internal liquid circulation.

  • High-Rate Biogas Digesters: For anaerobic digestion systems designed to process organic matter and generate biogas.

  • Anaerobic Contact Reactors: For anaerobic wastewater treatment systems that retain and recycle biomass.

Dosage and Direct Inoculation

BactaServe Anaerobic Granular Catalyst is ready for direct inoculation into suitable UASB, EGSB and IC reactors.

  • Direct Inoculation: Introduce the product into the compatible reactor according to the application requirements.

  • Dosage Assessment: Determine the required quantity based on reactor design, hydraulic retention time (HRT) and organic loading rate (OLR).

  • Reactor-Specific Dosing: Establish the appropriate dosing protocol according to the system configuration and treatment requirements.


The required quantity should be determined for the individual reactor rather than applying a universal mixing ratio.

Important Application Considerations

The performance of anaerobic granular biomass depends on reactor configuration, wastewater characteristics and operating conditions.

  • Reactor design: Confirm suitability for the existing UASB, EGSB, IC or other compatible anaerobic system.

  • Hydraulic retention time: Consider HRT when determining the appropriate dosage.

  • Organic loading rate: Evaluate the organic load entering the reactor.

  • Biomass retention: Monitor settling and biomass washout to assess reactor performance.

  • Process stability: Observe changes associated with hydraulic and organic shock loads.

  • Treatment performance: Monitor relevant parameters, including VFA levels, BOD, COD and biogas generation, as appropriate for the system.
