Greasezilla selected to Virginia FOG sanitation project

December 3, 2019 |

In Virginia, Greasezilla announced it has been selected by Hampton Roads Sanitation District (HRSD) to provide the most cost-effective and ecologically sound FOG (fats, oils and grease) Separation Technology for the Nansemond Treatment Plant in Suffolk, Virginia. HRSD did an industry-wide search for the most efficient and advanced system to separate FOG into its basic components, sending the water back to the treatment center headworks and responsibly recovering advanced biofuel. The construction of the new facility is expected to begin in Spring 2020.

Jacobs, the leading provider of technical, professional and construction services, will be responsible for placement of the major system components and is overseeing the facility – which will screen, decant and process the FOG from indirect haulers. The Greasezilla system will sit ahead of the wastewater treatment facility and process up to 40,000 gallons per day, which equates to 7.5 million gallons of FOG per year and beyond, as it is completely scalable.

Greasezilla’s two-tank, two-boiler system heats the FOG to create separation, requiring no additives, additional processing, blending or fossil fuels. After separation, the brown grease is pumped into holding tanks and has now become an advanced biofuel that is a carbon positive substitute for high-sulfur bunker fuel (No. 5 and No. 6 fuel oil). It burns clean and has a small physical footprint when compared to corn or soy. The remaining water content, which is pasteurized and nearly free of all suspended solids, is now safe for discharge into the wastewater treatment facility.
