PC-750 Belt Filter Press Replacement Project, Detroit Water and Sewerage Dept. (DWSD)

DeMaria was hired by the City of Detroit Water and Sewerage Department (DWSD) to replace 16 belt filter presses with 8 new certrifuges located on the lower level of Sludge Dewatering Complex II at the wastewater treatment plant in Detroit, MI. The project required close coordination with the plant's operational and maintenance groups in order to keep plant operations fully functional during construction.
