ESG-EWSU Centrifuge Improvements
Evansville, Indiana
The Evansville Water and Sewer Utility (EWSU) is pursuing operational cost savings at their East Wastewater Treatment Plant (East Plant) by replacing their existing sludge dewatering equipment. Currently, primary sludge is pumped from EWSU’s West Wastewater Treatment Plant (West Plant) to their East Plant where all sludge processing takes place. Sludge is currently processed by four belt filter presses (BFPs) rated at 175 gallons per minute (gpm) maximum input. This project includes replacing all four BFPs with two centrifuges.
The centrifuges will process as much as 250 gpm each, with one unit capable of processing all the sludge if desired by EWSU. The centrifuges will produce drier cake than the existing BFPs (i.e., 29% vs. 18%), thereby lowering disposal costs benefiting EWSU. This project is part of a larger guaranteed savings project and will be constructed as design-build to control costs and complete sooner. The design-build team completed early coordination with the Indiana Department of Environmental Management to help expedite the construction permitting phase.
