Bar screen effectively prevents pumps from cloggingProblem: New Jersey’s Lower Township Municipal Utilities Authority operates a 5 mgd wastewater treatment plant. Influent arrives through a 48-inch pipe 23 feet below grade. The manual inflow pump screening setup was difficult and hazardous to clean, and the 2.5-inch screen spacing let too much nondispersible waste through. The 3,000 gpm non-clog pumps clogged constantly, and each day two or three workers had to descend a 26-foot stairwell into a dark, hazardous environment to remove debris from the screen. Matthew Ecker, executive director, calculated the labor cost alone at over $26,000 a year.Solution: Aqualitec
