Septage & Grease Tanks

Septage and grease receiving programs are increasingly being added to the list of services wastewater treatment facilities provide. Acceptance of septage and grease from waste haulers has environmental benefits and can prevent the inevitable issues of fat, oil, and grease (FOG) being discharged into the sewer system. It is common for facilities to receive septage and grease into a holding tank and then introduce the flow gradually as not to upset the treatment process.

A BioMix Compressed Gas Mixing System keeps holding tank contents homogenized and prevents grease cap formation. Moreover, the straightforward system minimizes the maintenance of in-tank equipment.

“When we needed to clean the previous system, I had to put a whole crew on it. Using EnviroMix, one man can clean a tank from the topside using a high-pressure hose. That’s a big advantage because we have to minimize downtime.” Greg H. – South Carolina WWTP


Energy Efficiency Icon
Energy Efficiency
  • Energy savings of 50% or greater over diffused air or mechanical mixing technologies
Straightforward Operation Icon
Straightforward Operation
  • Non-clog, maintenance free performance
  • No motors or electrical components in the tank requiring maintenance
  • No rotating equipment or sharp edges, lowering risk of trash and debris collecting on equipment
Process Optimization
  • Vertical mixing regime that breaks the surface of the liquid dissipating unemulsified fat, oil, and grease (FOG)
  • Ability to develop a homogeneous mixture as opposed to simply stirring
  • Variable mixing intensity capabilities based on changing depths and differences in substrate characteristics
Unparalleled Flexibility Icon
Unparalleled Flexibility
  • Ideal for sloped floor or conical tank bottom configuration, thereby eliminating dead zones
  • No low water level limitations — able to mix at any depth
