Treat Fats, Oils and Grease (FOGs)


FreshAWL® Z-FOG™ is the answer Wastewater Treatment Plants (WWTP) obtaining Zero problems with Fats, Oils and Grease (FOGs).
Manufactured according to the EPA's standards for DfE, FreshAWL®Z-FOG™ will ZERO out problems with Fats, Oils and Grease (FOGs). Z-FOG is the true answer for Wastewater Treatment Plants (WWTP) to eliminate system clogs and build up of FOGs in:
  • Lift stations
  • Transfer Lines
  • Wet Wells
  • Headworks

WWTP systems treated with Z-FOG will also be free of FOG related odors because the FreshAWL molecular chemistry eliminates the formation of hydrogen sulfide (H2S) odors coming from the FOG eating bacteria. WWTP operators can rest assured that Z-FOG is safe because Z-FOG does not contain:

  • No Enzymes
  • No surfactants
  • No emulsifiers
  • No solvents

Z-FOG works by disrupting the hydrophobic and colloidal bonding of grease logs and cakes. It continues to work by preventing colloidal adhesions of the FOG molecules from sticking to each other or to walls, chains, pipes and equipment. Systems treated with Z-FOG will not be subject to grease logs, cakes or plugs forming in the piping systems, grease interceptors, wastewater collection lines and lift stations.

A Nevada WWTP collections system had an 18 inch diameter pipe transporting wastewater from restaurants to a lift station. The Lift station was off-gassing H2S at between 10 and 20 ppm. 35,000 gallons per day were supposed to flow through this pipe, but FOGs restricted the flow which had to be redirected to an alternate line. The WWTP shut down the line and allowed FreshAWL to treat the clogged run. 5 Gallons of Z-FOG were poured into the 4,000 gallons of water filling this line. The line was shut down for 18 hours before flushing. Once the system flow was redirected back through the line the fat logs and clogs blocking the line were washed right out.

  Wastewater flow gdp H2S ppm
Baseline Measurement 4,000 11.5
After 5-gal. Z-FOG™ treatment 35,000 0

The line was then free to be used again and the odors that had been coming from the pipe were eliminated.

The once necessary and costly hydro-flushing and snaking were also eliminated!

The above example is one of many that speak to reduced costs of labor and equipment required to keep collection services running. Z-FOG eliminates the labor cost of digging FOGs out of lift stations. A small weekly addition of Z-FOG also saves on system corrosion and odor complaints coming up from neighborhood manholes.

WWTP operators will be pleased to know that FreshAWL Z-FOG:
