Product at a glance

  • Powder product for FOG degradation containing beneficial Bacillus and additional free enzymes
  • Enzymes provide an immediate response whilst the Bacillus provide a longer, sustained solution
  • 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, therefore preventing the formation of FOG issues further downstream.
  • Able to improve COD, bulking and floatation issues associated with fats, oils and grease.
  • Reduces instances of blockages and number of call outs to maintain grease traps and interceptors.

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

COD contributions from FOG in effluents

Municipal and industrial wastewater plants

Grease traps and interceptors

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, fouling, foaming and floc floatation as well as promoting the growth of filamentous bacteria. In many wastewater systems the present microbial population may not have the necessary tools to deal with the growing challenge of FOG.

Evogen FOG has been formulated to address the limitations of waste water systems such as grease interceptors and traps in dealing with fats, oils and grease from a variety of sources.

The unique blend of superior FOG degrading microorganisms combined with a selection of enzymes offers both a rapid and prolonged response to the degradation of organic materials.

How it works

The product works via a two-pronged approach in which the enzymes provide an immediate response to help loosen and liquify organic materials and FOG and the nonpathogenic Bacillus bacteria provide a longer more sustained response.

Typically, the resident microbes within a wastewater system lack the capability to fully degrade FOG leading to issues associated with clogging, bulking and floc floatation. Using both classical microbiology and cutting-edge genomic investigations, Genesis Biosciences have put together a consortia of Bacillus bacteria that can degrade FOG fully down to CO2 and water. This has been achieved by combining microbes that secrete a diverse range of enzymes and biosurfactants to break down different FOG types to more digestible components, allowing the Bacillus to colonise a system using the FOG as their food source. This action helps to maintain the integrity of services, reducing the need to empty units as often as well as decreasing the likelihood of blockages due to FOG deposits.

Further to FOG degradation, diverse extracellular profiles of the Bacillus allow for broad substrate utilisation enabling the degradation of a range of animal and plant materials in effluents improving both effluent and sludge parameters.

Directions for use

Evogen FOG is supplied in 20kg containers and also in 200g or 400g water soluble bio-pouches.

The bio-pouches are intended for single dose. We recommend that one bio-pouch is used per day for most situations. Simply add the bio-pouch to tepid water, mix for a few minutes and pour the solution into problem drains including those leading to grease traps.

Evogen FOG should be dosed at times of little or no activity, or at times of slow flow. This helps to optimise conditions for biodegradation of grease and other target substrates.


Due to the biological nature of the product extremes of temperature and pH should be avoided. Care should be taken to ensure harsh chemicals, biocides, sanitisers or bleaches are not added to the drain line, grease trap or toilet system prior to or immediately following product application.


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.

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, should harbour no toxicity towards humans or animals and do not have a negative impact upon the environment. T

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