Wastewater Treatment Plants
FOG is an industry-wide problem. Greasezilla’s℠ FOG receiving stations are the solution.
Water and wastewater facilities spend billions of dollars each year on FOG-related blockages and backups. As operational expenses, sustainability directives and environmental regulations increase, the industry is struggling to maintain compliance. Facilities that fall below standards are subject to fines, penalties and court-enforced consent decrees.
According to the Congressional Budget Office, U.S. water and wastewater O&M expenditures are projected to reach $93.8 billion by 2027. The EPA and state agencies are fervently pushing for ecological upstream solutions to improve operations and sustainability.
Greasezilla℠ provides an ecological and cost-effective turnkey solution for fats, oils and grease processing.
No chemicals. No landfilling. No waste.
Ecological.
Efficient.
Economical.
Greasezilla℠ separates FOG into its basic elements, sending the water back to the wastewater treatment center headworks and recovering highly profitable Brown Grease Advanced Biofuel (ABF). This end-to-end process is the most ecologically advanced system available. Greasezilla℠ is unique in that it is powered by the same clean ABF it produces and leaves nothing to be landfilled or disposed of.
Our customers range from small municipalities to large commercial operations. Recently, Hampton Roads Sanitation District (HRSD) selected Greasezilla℠ to provide FOG separations for its Nansemond Treatment Plant.
“The system works great and answers a real need in the wastewater treatment industry. And now we can handle increased tipping fee volume and make money on the commodities sales side as well.”
How does Greasezilla℠ work?
Step One: FOG receiving
As a hub for regional grease collection, Greasezilla℠ technology will handle grease on the front end, assisting in compliance with EPA national pretreatment standards, including CFR 40 403.2 and CFR 40 403.5 that strive to prevent pollutants from causing obstructions and other interference that might interfere with operations.
Greasezilla supports local FOG programs by ecologically processing collected FOG without the need for polymers or other additives. The process diverts FOG from landfills and incinerators, lowering operational costs and helping communities achieve their sustainability goals.
Greasezilla℠ accepts grease trap waste from haulers as well as grease skimmed from scum tanks and clarifiers from other area plants. The FOG entering the system provides the raw material needed for the next step in the process.
Step Two: FOG separation
At the heart of FOG receiving stations, Greasezilla℠ processes the FOG into three distinct layers:
1. Brown Grease, approximately 15 percent of the finished process, is converted into a rich, advanced biofuel. Five percent of the ABF returns to fuel Greasezilla℠, and the remaining 95 percent can be used for other heat requirements at the plant or as a salable fuel substitute on the commodities exchange. The low-moisture content (less than 1 percent) also makes the ABF an excellent feedstock for biodiesel conversion technologies.
2. Batter, making up 5 percent of volume, can serve as an excellent feedstock for anaerobic digesters. It can also be treated with traditional processes, composted or be processed with the effluent water.
3. Residual pasteurized effluent water, comprising approximately 80 percent of the material and nearly free of suspended solids, can be safely discharged into the wastewater treatment facility.
Step Three: Biofuel sales
As a service to our clients, Greasezilla℠ developed an international distribution network, a proven channel that provides the best value for the Brown Grease commodity while filling a rising demand for alternative fuels worldwide.
