Terminal pumping stationTerminal pumping stations receive municipal wastewater from network pumping stations. Installed in dry or wet wells, the pumps forward the medium to a treatment plant for final purification. Due to the lack of screens at most pumping stations, difficult materials such as fibrous sanitary and packaging items are a constant threat to uptime.
Inlet pumping stationInlet pumping stations are somewhat similar to large terminal pumping stations. Depending on the depth of the incoming sewer, the lifting heads can range from around 2 up to 30 meters. To prevent hydraulic shock loads, which negatively impact the biological process, the stations often make use of variable-speed drives and/or several pumps in parallel.
Outlet pumping stationsOutlet pumping stations are required when the level of the treatment plant is lower than that of the receiving water. This is especially true when discharging into a river, which can rise during heavy rain or flood periods, or into the sea, where the level varies with the tide. Outlet pumping stations may also be needed to compensate for increasing frictional losses in the outgoing pipe at high flows, for example in long sea outfall pipes.
Return of activated sludgeOutlet pumping stations are required when the level of the treatment plant is lower than that of the receiving water. This is especially true when discharging into a river, which can rise during heavy rain or flood periods, or into the sea, where the level varies with the tide.
Storm water pumping stationDuring heavy rainfall, storm water pumping stations deliver large volumes of water at low head to receiving surface waters or sewers. Having long been a part of flood management, they are increasingly involved in climate adaptation strategies for low-lying coastal cities.
Storm water retention tankStorm water retention tanks act as a buffer during periods of heavy rainfall. This is increasingly important as areas become more developed, with hard surfaces such as roofs, roads and parking lots that cannot absorb the rainwater. When storm water retention tanks are implemented, gravity or pumps can be utilized to provide a reduced continuous flow into the sewer system. Sulzer expertise makes it possible to avoid peak hydraulic loads and to limit the stresses on existing sewer systems.
Flood controlClimate change is challenging natural disaster prevention. When water runs off the land in large quantities, Sulzer’s comprehensive range of pumps provide reliable, cost effective and efficient solutions for flood control.
Industrial water and effluent treatmentSulzer has a deep knowledge in wastewater treatment, and with our wide product portfolio we can now offer energy-efficient and reliable solutions for your water collection, neutralization, flocculation, sedimentation, cooling, aeration, sludge storage, digestion, and dewatering processes.
