At Grünbeck, we have developed a deferrization installation that uses the best technologies for removing iron from groundwater: the fermaliQ. This iron removal installation combines oxidation with filtering, thus removing odors caused by hydrogen sulphide or ammonium.

Our new iron and manganese removal installation - fermaliQ - can be found below. This installation is unique in that it combines numerous process phases into a single system. Odors like hydrogen sulphide or ammonium are no longer a problem thanks to the smart mix of oxidation and filtering, and aeration assures the ejection of carbon dioxide, which increases the pH. The iron and manganese are oxidized into solid form and filtered out along with other undesirable particles when the pH is just correct. The particles are flushed out of the filter by a fully automatic backwash, and the process can begin again. This guarantees that the water is free of iron, manganese, and other contaminants.
