Sludge Degritter System Project
USD Project Manager: Kevin Chun
Contractor: Kiewit Infrastructure West Company
Awarded Contract Amount: $1,436,000
Estimated Completion Date: 11/2017
This project will include the installation of a new Sludge Degritting System and associated piping, valves, fittings, and controls along with a shaftless screw conveyor to transport dewatered grit to the existing grit hopper.
The degritter equipment removes grit through a two-stage system. It first separates the grit from the primary clarifier sludge then dewaters the grit. The dewatered grit is discharged into a hopper for the removal by truck to landfill for disposal, while the sludge is conveyed to the Thickener Control Building for further treatment.
