The ASN 5300 Series removes stubborn iron without chemicals!
Using a DUAL TANK system, incoming water passes through a compressed pocket of air contained in the tank. The oxygen precipitates the iron into solid form and is removed when it passes through the filters media bed. Birm acts as a catalyst in the reaction between iron and oxygen that also causes the iron to precipitate into a solid. As more water passes through the unit the air becomes depleted and the birm becomes overloaded with the 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.
