The HFS Chemical Free Iron Filter is not only very low maintenance, it also regenerates less frequently than traditional iron filters, using up to 50% less water. Natural oxidation removes iron without chemicals, air pumps or venturi’s.
Incoming raw water passes through a compressed pocket of air contained in the first tank. The air precipitates the iron into solid form and is removed when it passes through the filters birm media bed contained in the second tank. Birm acts as a catalyst in the reaction between iron and oxygrm that also causes the iron to precipitate into solid. As more water passes through the unit, the air becomes depleted and the birm becomes overloaded with iron. Periodic automatic regeneration replenishes the supply of air and cleans the media of filtered iron. Birm is not consumed in the iron removal process and therefore is much more economical than many other iron removal processes.
