Potable-water treatment is based on common salt

Grundfos, potable water treatment

The Grundfos Selcoperm electrolytic chlorination system uses common salt to disinfect water and is an approved disinfection method complying with the Drinking Water Inspectorate regulations for drinking water. The sodium hypochlorite solution produced has a pH of 8 to 8.5 and a maximum equivalent chlorine concentration of less than 8 g/l. Its long life makes it ideal for storage in a buffer tank.

There are over 300 installations of the system, and they have proved to be reliable and robust alternatives to chlorination. The electrolysis of a common-salt solution is economic.

Selcoperm systems are also suitable for treating swimming pools and are supplied as turnkey solutions.
