Overview Many commercial operations generate high- strength wastewater. Fats, oil and grease (FOG) tend to clog leaching systems. Dairy products present a challenge to the primary wastewater treatment. System management through Ordinance 75. New technologies.
What’s the problem? My septic system is working just fine. The pollution that is seeping into the ground water cannot be seen. Some systems do not include grease traps or filters. Migrating solids and globules of “FOG” products are blocking the leaching systems.
DEP FOG Program Renderable grease is processed into Tallow. Recovered oil is added to diesel, creating Biodiesel. Concentrated grease is disposed through incineration.
Step 1- Settling tank (Similar to a Septic Tank) Purpose is to remove solids and begin digestion process Step 2 - Oxidation Air introduced to promote waste breakdown on small volume. All remaining solids removed. Solids circulated between tanks to encourage breakdown. Fixed Media bed to grow biological agents that consume the waste Step 3 - Sterilization Ultraviolet light kills any viral or bacterial components. Clear plastic tubes expose water to UV Light
Drinking Quality Water will eventually find its way into the ground water. Step 4 – Sub-Surface Galleries (Similar to a Leaching Field) Water is then recharged to ground water through a series of sub-surface structures
