A centrifugal pump is the most commonly used wastewater pump. They are used most commonly for raw wastewater pumping; at lift stations, recirculation flows, for return activated sludge, waste activated sludge, and final effluent pumping.
They are available either in a complete unit which includes its own pump, or in a modular form that requires an additional pump. The modular units are useful when plumbed in-line with other types of filtration, such as a wet/dry filter. The complete units use a u-tube as the water intake and typically a spray bar for the water return.
