Proprietary wastewater treatment system removes FOG (fat, oil and grease) from industrial effluent using no chemicals and generating no sludge. Highly effective, low-cost FOG removal technology with low carbon footprint reliably achieves water quality compliance on wide variety of waste streams on volumes from 100 to 600,000 GPD. Extracted oil is highly concentrated for resale as biodiesel feedstock. Widely used to process industrial wastewater in food processing, surfactant production and manufacture of creams and lotions. Also used to de-water and purify fat, oil and grease streams for further value-added processing.
