A raw water reservoir does not simply hold water until it is needed. It is the first part of the water treatment process. The retention time – the time the water is held in the reservoir – is a design feature that allows particles and silts to settle out, as well as time for natural biological treatment using algae, bacteria and zooplankton that naturally live within the water.
Grundfos can supply all components for managing a water reservoir, where the requirement is to keep the water moving and oxygenated with mixers and flowmakers, with the careful control and adjustment of water quality with a dosing system.
Changing load conditions require a pump system that can handle large flows at low head. Where tank design doesn’t allow the use of flowmakers, Grundfos AMD and AMG mixers offer a robust design with corrosion resistant materials, easy service and maintenance, and trouble-free operation in difficult environments.
Traditionally, chlorine compounds are the most widely used method for chemical disinfection. Grundfos can advise and supply disinfection solutions using chlorine compounds such as chlorine gas (Cl2), sodium hypochlorite (NaOCl), and chlorine dioxide (ClO2).
Grundfos can supply complete dosing pump systems for large or small volumes and based on different technologies for flocculation, disinfection, and pH adjustment. Moreover, the Grundfos range of electronic and electrochemical accessories offers complete control of your dosing and disinfection processes and can be seamlessly integrated into your system.
Grundfos can supply the specialist expertise to help meet your performance objectives, from the initial identification of needs, to the selection, installation, operation, and maintenance of the pumping solution. Grundfos commissioning agreements ensure correct installation and service agreements cover all eventualities, from routine maintenance to spare parts and pump audits.
