ABSTRACT:
Water purification systems utilizing oxidation. By passing water through a chamber of air, the impurities within the water, such as iron, manganese, and/or hydrogen sulfide gas, may be oxidized. The oxidized constituents in the water may then precipitate out and be removed by filter media. Thus, by utilizing oxidation, the impurities most commonly found in a consumer's water are readily removed. Additionally, the water purification systems of the present invention may also elevate the pH, i.e., reduce the hydronium ion concentration, of the water when the water is acidic. By raising the pH of the water, the oxidation of impurities, such as iron and manganese, is more complete and also occurs at a faster rate. Additionally, the corrosivity of the water is also reduced when the pH is elevated.
