FermaliQ oxidation filter systems from Grünbeck AG are a unique combination of several process stages and a special filter layer in one compact water treatment system.
The biggest advantage of the system is its ecological operation without the use of any chemicals. Degassing and oxidation take place by spraying and aeration. This effectively reduces odorous substances such as hydrogen sulfide and ammonium; in addition, the pH value is increased by eliminating free and therefore aggressive carbonic acid. Iron, manganese and other impurities are then removed by several filter layers. Regeneration takes place automatically by backwashing with treated water. The device does not require constant maintenance and has very low operating costs.
