GRD filters - iron and manganese removal, KMnO₄ regeneration
Iron and manganese removal is used to improve water quality. Iron and manganese ions not only affect the formation of brown stains and calcium deposits, but also cause excessive growth of iron and manganese bacteria, which reduce the service life of water pipes by depositing on their inner walls. Filtration systems eliminate various forms of dissolved, precipitated and bacterially bound iron and manganese from water. The iron and manganese filters can treat water for water boiler rooms, cooling circuits, industrial and domestic installations as single units or as part of a pre-treatment station upstream of other units (e.g. reverse osmosis).
Available control versions:
- with the electronic timer 740; starts the regeneration process after a pre-set time,
- with the electronic timer 742; starts the regeneration process after a pre-set time; adjustable backwash and forming time.
