The City of Danbury’s newly renovated wastewater treatment plant incorporates a biodiesel production system that eliminates the cost and environmental impact of landfilling or incinerating fats, oils and grease.
The system at the John Oliver Memorial Sewer Plant created a new revenue stream from the sale of biodiesel produced on site in an automated and continuous-flow process.For the project, REA Resource Recovery Systems designed an 18,500 gpd FOG receiving station to increase the city’s capacity to accept grease trap waste hauled in by contractors. The system includes odor-control equipment.Preprocessing of the FOG removes 99% of water to prepare the brown grease
