Applications

Applications

  • Flood control
    Climate 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 treatment
    Sulzer 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.

  • 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.

  • Storm water pumping station
    During 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.

  • Water supply
    Meeting today’s challenges and high requirements within water intake, sedimentation, sludge treatment, fine screening, and water distribution processes.
Case studies
  • Efficient storm water protection and ecological balance
    Sulzer delivers large axial propeller pumps with a total motor power of more than 4 MW for the Integrated Rhine Program (IRP) at Polder Rheinschanzinsel in Germany for flood protection. As part of the IRP, the regional authority of Baden-Wuerttemberg in Karlsruhe is building a retention area for flood control near Philippsburg in Germany.

  • Extensive irrigation project in San Salvador in Spain
    The objective of the reservoir of San Salvador, in the province of Huesca, northeast Spain, is serving the demands of 22’400 hectares and improving the irrigation system of the Canal of Aragón and Catalonia from the previous annual volume of 5.3 km³ up to 6.8 km³.

  • Optimizing efficiency of Spanish irrigation project
    Increasing the volume of water available to an irrigation channel in Northeast Spain was necessary for local agriculture, especially during the dry summer season. The desired outcome of this expansion project was to successfully commission the reservoir of San Salvador with energy consumption kept to a minimum.

  • Sulzer secures contract for Danish climate protection scheme
    Nine Sulzer pumps are set to play a key role in new flood defenses around the town of Ringkøbing. Danish water utility Ringkøbing-Skjern Forsyning A/S has selected Sulzer as the primary pump supplier for a major flood defense project.
