Client: Spartanburg Water
Cost: $5.5 Million
Spartanburg Water owns and operates a 64 MGD conventional surface water treatment plant. Sludge generated in the sedimentation basins is manually removed, thickened, and generally land applied when weather permits. HMW provided analysis of sludge generation quantities , removal methods, and efficiency of the existing spray land application system. HMW provided design for an improved sludge management system which included: sedimentation basins continuous sludge removal system and conversion of manual decanting/thickening to continuous overflow gravity thickening.
The system is designed to optimize sprayfield use and limit other more costly methods of disposal (geotube dewatering to landfill, sludge drying beds to landfill).
