Collection System

Fats, oils and grease (FOG) cause many complications in municipal wastewater treatment. Excessive FOG can foul sensors in wet wells, promote growth of filamentous bacteria, cause foam, impact dewatering and cause permit violations. Physical removal can be costly, labor intensive and increase operating time. FOG is biodegradable, but in many systems the microbial community does not contain enough of the right microorganisms to keep FOG levels under control.

We provide liquid and dry solutions for reducing FOG


Our patented blends of microbes contain both spore-forming and vegetative strains capable of degrading long-chained fatty acids, proteins, lipids and carbohydrates. Liquid and dry products are available for a wide range of applications involving problematic accumulations of FOG in both treatment plants and collection systems.


Hydrogen Sulfide

Collection systems can have odors due to long residence time and low flows. If odors go unaddressed H₂S can form and cause corrosion and hazardous conditions. Using caustic and other harsh chemicals can be dangerous.

Preventing the H₂S from forming is essential. This can be done biologically or with calcium nitrate.  If H₂S has already formed it can be degraded biologically with OdorCap 5700 or oxidize it with GCPRO Oxidizer.


Wet Well Aeration & Mixing

The most advanced technology to dissolve FOG, eliminate odors and septicity of hydrogen sulfide in the wet well is adding aeration and mixing systems.  By starting mixing in the collection system you begin to pre-process the water and create an aerobic environment to improve the wastewater plant operation.

Aeration added to a wet well removes fats, oil and grease by adding up to 5 ppm of dissolved oxygen, injecting ozone to eliminate H₂S and odors and allowing for microbial activity in wet well to become aerobic for continuous degradation of organic matter.
