Grundfos provides water-treatment pumps serving all relevant treatment steps, including substance removal, disinfection, stabilisation, monitoring and control. All the pumps can be combined in an intelligent way, offering accurate dosing of additives before or during treatment, and all can be supplied with systems that measure and control key parameters. Desalination Around97%of all water onEarth is saltwater. Pollution, population growth and other chal- lenges have led to a decrease in freshwater, and desalination is becoming a vital source of potable water.
