Grundfos Solutions

Even with a good water source, water treatment should be considered to ensure good water quality. Water treatment describes those processes used to make water more acceptable for a desired end-use and to ensure that stringent quality standards to the consumer are maintained. Grundfos can supply pumping solutions for solids separation using mechanical treatments such as settling and filtration, dosing solutions for chemical treatments such as disinfection and coagulation.

Grundfos solutions are designed specifically for pumping installations and all the components are fully integrated from the outset. Life Cycle Cost analyses have shown how this seemingly complex and costly process results in tangible benefits for owners. Grundfos commissioning agreements ensure correct installation and service agreements cover all eventualities, from routine maintenance to spare parts and pump audits.
