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.
While most pumps are used for water, centrifugal pumps are also used for sewage, petroleum, and chemicals. Incidentally, the reverse of this process is called a water turbine. The impeller is placed in moving water; it can be used as a water turbine which converts the waterâs energy into rotational energy.
