Drawing surface water from a shallow well at a lake shore or river bank provides easily treatable water that has been naturally filtered. Where substantial water flows are required, surface water offers an excellent supplement to pristine water sources such as spring water and groundwater.
Grundfos can tailor pumping solutions that take account of the varied demands of surface water resources. Seasonal changes to river and lake levels mean that submersible multistage SP pumps are ideal for these applications with periodic uncontrollably high water levels.
As lakes and rivers may have been exposed to pollution and pesticides, a careful balance needs to be maintained between slow filtering through a lakeside or river bank well and the optimum chemical disinfection. Adding the benefits of remote management could mean savings of up to 20% on power consumption, chemicals and testing at final treatment.
The fully automated disinfection systems developed by Grundfos offer an easy solution for chlorine-based disinfection methods. Grundfos can advise and supply disinfection solutions using chlorine compounds such as chlorine gas (Cl2), sodium hypochlorite (NaOCl), and chlorine dioxide (ClO2).
By integrating variable speed drives and motor protection components, Grundfos can offer complete systems that are pre-engineered to work together. Grundfos CUE frequency converters represent one of the most comprehensive and versatile ranges of external variable speed drives for pump applications currently on the market. Together with the easy to use MP 204 motor protection, we ensure 24-hour monitoring and control of all vital parameters, such as dry-running or overload, to ensure operational stability.
Grundfos can supply the specialist expertise to help meet your performance objectives, from the initial identification of needs to the selection, installation, operation, remote monitoring and maintenance of the water handling solution. Grundfos commissioning agreements ensure correct installation and service agreements cover all eventualities.
