  • Commercial waste disposal from toilets
    Commercial wastewater from toilets comprises all sewage water flushed from toilets on commercial, industrial or public properties.

  • Network pumping station
    Network pumping stations collect municipal wastewater from residential homes and communal schemes. Installed in dry or wet wells, the pumps deliver the effluent to a terminal pumping station. Since most pumping stations are not equipped with screens, the pumps must cope with difficult materials such as fibrous sanitary and packaging items.

  • Terminal pumping station
    Terminal 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 station
    Inlet 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 stations
    Outlet 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 sludge
    Outlet 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.
