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.
Septic Systems Maintenance: A typical septic system consists of two basic components: a septic tank and an underground disposal field. Wastewater flows from the house to the septic tank. Effluent, after the solids have settled out of the wastewater, flows from the tank to the drainage field.Most septic systems operate by gravity. Thus, it is a passive system, perhaps one of the best passive systems we have to serve our homes.thers may require a pump (sewage ejection or grinder pump) to pump the wastewater from the house to the septic tank. The simpler system is the one using an effluent pump. A sewage ejection or grinder pump is a more complex piece of equipment that requires more maintenance.
