Microbes for FOG removal

The operational and environmental impacts of FOG

Fats, oils and greases (FOG) degrade comparatively slowly and have high biochemical oxygen demand (BOD). They're also insoluble in water. So when they build up in wastewater treatment plants, they cause a wide range of problems. In municipal plants, they cause fouling of lift stations, transfer pumps and transfer lines. In food processing plants, FOG-rich wastewaters can overload dissolved air flotation (DAF) units and other separators. The results can be challenges in your operations and high chemical costs. Restaurant grease discharge means grease traps have to be used. These need frequent pumping to remove the built-up grease. They may also lead to surcharges for wastewater services. In septic systems, grease build-up can cause drainage field failure and can ultimately lead to costly replacement. Discharge of excessive amounts of FOG into waterways can lead to surface deposits, drops in dissolved oxygen and loss of wildlife.
