Wastewater Technology Fact Sheet: In-Plant Pump Stations
United States Office of Water EPA 832-F-00-069. Environmental Protection Washington, September 2000. Agency Wastewater Technology Fact Sheet In-Plant Pump Stations DESCRIPTION. TABLE 1 PUMP APPLICATION. The terrain of the treatment plant site and the Pump Type Typical influent sanitary sewer depth govern the need for Application and location of In-Plant pumping facilities. In-Plant Centrifugal Raw Wastewater Flush Water pump Stations are facilities that consist of pumps Primary Sludge Spray Water and service equipment designed to pump flows from lower to higher elevations to allow continuous Secondary Sludge Seal Water and cost-effective treatment through unit processes Effluent Wastewater within the plant. Positive Primary Sludge Displacement The type of pumps most commonly used at Wastewater treatment plants include the centrifugal, Thickened Sludge progressive cavity, and positive displacement.
fabricated pump stations generally have capacity of up to 38,000 lpm (10,000 gpm). Usually, pump stations include at least two constant-speed pumps ranging in size from 38 to 75,660 lpm (10 to 20,000 gpm) each and have a basic wet-well level control system to sequence the pumps during normal operation. The most common method for pump control uses
