Engineered to utilize aeration and adsorption technology to oxidize and remove hydrogen sulfide and iron, without the use of salt or chemicals. Oxidation of iron and hydrogen sulfide gas is initiated as the water passes through a compressed pocket of air. Dissolved oxygen-enriched water now continues through a catalytic media, enhancing the oxidation reaction and producing precipitates that are easily filtered. Accumulated sediment is backwashed out daily and a new air pocket is formed.
