Product at a glance

  • Liquid concentrate product containing chemical and biological mechanisms for FOG degradation.
  • Diverse lipase, esterase and biosurfactant capabilities make FOG deposits more bioavailable, breaking them down into more digestible components.
  • Bacteria capable of fully degrading the common components of FOG deposits such as palmitic, stearic, oleic and linoleic free fatty acids.
  • Able to improve COD, bulking and issues associated with fats, oils and grease.
  • Ideal for organic rich effluents such as municipal, dairy and slaughterhouse effluents.

FOG deposit issues in grease traps, interceptors, wet wells and lift stations

COD contributions from FOG in effluents

Municipal and industrial wastewater plants

In pipe dosing

Suited to effluents rich in organic materials

The technology

Fats, oils and grease in wastewater systems cause a range of problems including: excess BOD/COD contributions, clogging and fouling, foaming and floc floatation aswell as promoting the growth of filamentous bacteria.

Evogen GDL has been formulated to address the limitations of wastewater systems in dealing with fats, oils and grease. The unique blend of readily biodegradable surfactants combined with FOG degrading microorganisms offers a versatile solution to mitigate issues related to FOG. From dosing into sewer lines to wet wells and lift stations, the technology offers the wastewater operator a technology for controlling FOG across a range of scenarios.

The product works via a two-pronged approach, first a low concentration of a surfactant make FOG deposits more bioavailable, next the specifically selected Bacillus microbes fully degrade the FOG to CO2 and water. It is this combination that prevents FOG from simply traveling further downstream and forming hard scale as commonly found with enzymatic, chemical and poorly designed biological treatments.

Directions for use

Evogen GDL is supplied in 20L, 200L and 1,000L containers and is available at either a 1X or 10X concentration.

It can be dosed directly into sewer systems, pipes and wet wells (lift stations, manholes), grease traps or interceptors and/or directly into effluent streams.

For dosing instructions please contact technical support with details of your flows and loads. We would be more than happy to help.


Evogen GDL should be used in systems dealing with organic rich wastewaters that contain materials such as proteins, carbohydrates and fats oils and grease such as municipal plants, bakeries, dairies and slaughterhouses.


The product will perform poorly in highly alkaline (>pH 9) and highly acidic (<pH 4) effluents and will also lose activity at low (<15 ̊C) and high (>40 ̊C) temperatures. Effluent types rich in phenolic and hydrocarbon species such as those from wineries, olive mills or heavy industry are not suitable for this product.

For specialised effluent types contact our technical department for alternative solutions and more information.

Via both cell cytotoxicity assays and genomic screens for toxin production, we can confirm that all Bacillus species and strains within the product are safe to use, harbour no toxicity towards humans or animals and do not have a negative impact upon the environment.

From analysing the DNA of our strains we can also confirm a lack of mobile genetic elements, which strongly indicates a low potential for transmission of antimicrobial resistance (AMR) genes.
