Problem: The Fernandina Beach (Florida) wastewater facility was hauling 2.34 million gallons of wet biosolids annually. Landfill costs were rising and landfill availability was getting tight. Dewatering would reduce biosolids volume by 75%.
Solution: The city evaluated dewatering systems based on safety, maintenance, complexity, space required, loading on the headworks, operator time required and surface area to clean. As a result, the city chose a Fournier Rotary Press.
Result: The press enabled increased wasting to the digesters, improving operation of all process trains. “This system should last well over 20 years and should pay for itself in about seven years of operation,” says John Mandrick PE, utilities director. 800-463-6328; www.fournierdewatering.com
