Continuous Fat, Oil and Grease Treatment with BactaServe FOG SR Bar

Fat, oil and grease (FOG) can accumulate in grease traps, holding tanks and wastewater collection systems, contributing to unpleasant odours, oil scum and organic solids build-up. Regular treatment helps manage these deposits and supports the operational efficiency of wastewater infrastructure.


BactaServe FOG SR Bar is a slow-release microbial bar containing natural, non-pathogenic and acclimatised bacteria selected for their ability to degrade fats, oils and grease. The bar gradually releases active microbes into the water containing oil, providing continuous treatment over an extended period.

Key Benefits of BactaServe FOG SR Bar

BactaServe FOG SR Bar is designed to provide ongoing microbial treatment in suitable grease and wastewater systems.


  • Slow-Release Microbial Activity: Gradually releases active microorganisms into the water medium containing oil.

  • Continuous 24/7 Treatment: Provides ongoing microbial treatment without requiring repeated manual dosing throughout the day.

  • No Dosing Pump Required: Operates without the need for a dedicated dosing pump.

  • No Grease Trap Modification: Can be installed without modifying the existing oil and grease trap.

  • Fat, Oil and Grease Degradation: Supports the biological breakdown of accumulated fats, oils and grease.

  • Odour Reduction: Helps reduce unpleasant odours associated with FOG accumulation.

  • Reduced BOD and COD Associated with FOG: Supports the reduction of BOD and COD associated with fats, oils and grease.

  • Reduced Organic Solids and Sludge: Helps reduce organic solids and sludge build-up.

  • Reduced Oil Scum: Supports the reduction of oil scum in suitable wastewater systems.

How BactaServe FOG SR Bar Works

BactaServe FOG SR Bar contains natural, non-pathogenic and acclimatised bacteria selected for their ability to degrade fats, oils and grease. Once suspended at the inlet of an oil and grease trap, the bar gradually releases active microorganisms into the surrounding water.


The released bacteria support the biological breakdown of FOG, helping manage grease accumulation, associated odours, oil scum and organic solids.


The bar is gradually consumed during use. Its typical service period is approximately 25 to 40 days, depending on wastewater flow and the quantity of oil present in the effluent.

Applications of BactaServe FOG SR Bar

BactaServe FOG SR Bar is designed for wastewater collection and treatment points affected by fats, oils, grease and associated organic deposits.


  • Oil and Grease Traps: Provides slow-release microbial treatment to help manage accumulated FOG.

  • Holding Tanks: Supports grease and organic waste management in suitable holding tanks.

  • Equalisation Tanks: Helps address FOG-related accumulation in wastewater equalisation systems.

  • Aeration Tanks: Supports the management of FOG and associated organic matter in biological treatment systems.

  • Sewage Manholes: Provides ongoing microbial treatment in suitable sewage collection points.

  • Lift and Pump Stations: Supports FOG management in wastewater lifting and pumping infrastructure.

Suitable Treatment Locations and Installation

BactaServe FOG SR Bar is intended for installation at designated points where wastewater containing fats, oils and grease passes through the system.

  • Grease Trap Inlet: Tie and suspend the bar at the inlet of the oil and grease trap to allow gradual microbial release into the wastewater.

  • Holding and Equalisation Tanks: Consider placement where the bar can remain in contact with the wastewater and release microorganisms into the treatment medium.

  • Aeration Tanks and Collection Points: Assess the installation location according to the system configuration and wastewater flow.


The product is designed to work without modifications to an existing oil and grease trap or a dedicated dosing pump.

Product Usage and Replacement

BactaServe FOG SR Bar provides extended-release treatment rather than conventional daily liquid dosing.

  • Installation: Tie and suspend the bar at the inlet of the oil and grease trap.

  • Microbial Release: Active microorganisms are gradually released into the surrounding water containing oil.

  • Typical Service Period: Approximately 25 to 40 days.

  • Replacement Timing: Assess the bar's consumption and the operating conditions to determine when replacement is needed.

  • Operating Conditions: The service period depends on wastewater flow and the quantity of oil present in the effluent.

Important Application Considerations

The performance and service life of BactaServe FOG SR Bar depend on the wastewater conditions and installation location.

  • Wastewater flow: Consider the flow rate through the treatment location.

  • FOG concentration: The quantity of oil present in the effluent can affect the bar's consumption period.

  • Installation position: Suspend the bar at the inlet of the oil and grease trap for gradual microbial release.

  • Service life: Use the typical 25 to 40-day period as a guide, taking actual consumption and operating conditions into account.

  • Treatment requirements: Assess FOG accumulation, odour, oil scum and organic solids to evaluate ongoing treatment needs.

Why Choose BactaServe FOG SR Bar?

BactaServe FOG SR Bar is a slow-release microbial treatment designed for continuous FOG management in wastewater systems.

  • Extended-Release Design: Gradually releases active microorganisms over time.

  • Natural, Non-Pathogenic Bacteria: Contains naturally occurring, acclimatised bacteria selected for FOG degradation.

  • Continuous Treatment: Provides ongoing microbial release without a dedicated dosing pump.

  • Simple Installation: Can be suspended at the inlet of an oil and grease trap without modifying the trap.

  • Multiple Treatment Locations: Suitable for consideration in grease traps, holding tanks, equalisation tanks, aeration tanks, sewage manholes and lift or pump stations.

  • Extended Service Period: Typically consumed over approximately 25 to 40 days, depending on flow and oil content.


BactaServe FOG SR Bar can be considered for facilities seeking continuous microbial support for grease management, odour reduction and control of FOG-related organic build-up in wastewater infrastructure.
