Natural oxidation removes iron, manganese, and sulphur without chemicals, air pumps, or a venturi.
Raw water passes through a compressed pocket of air precipitating the iron into solid form. The iron is then removed as it passes through the media bed contained in the second tank. The media acts as a catalyst in the reaction between iron and oxygen that also causes the iron to precipitate into a solid.
Periodic automatic regeneration replenishes the supply of air and cleans the media of filtered iron. The media is not consumed in the iron removal process making this an economical and low-maintenance solution.
