Systems and methods for conditioning sewage having entrained solids which clog sewage pumps, are disclosed. Systems include a sewage pump, a chopper pump, and a mixing nozzle connected to the chopper pump. Specifically, the sewage pump is a non-clog centrifugal pump having an inlet for drawing fluid into the pump and an outlet for discharging the fluid into a pipe, while the chopper pump has an inlet for drawing fluid into the pump and an outlet for discharging the fluid into the wet-well. The chopper pump may be positioned either in or adjacent to the wet-well. The mixing nozzle fluidly coupled to the chopper pump discharge, is positioned in the wet-well. Methods include the steps of positioning a chopper pump within the wet-well, drawing in liquid sewage, including the entrained solids, reducing the size of entrained solids, and discharging the sewage and reduced size solids into the wet-well. |
