Remove Stubborn Iron Without Chemicals
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
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.
