Removing iron and manganese Series
Apart from the application of iron and manganese in groundwater and the water to form iron-carbonate water quality. When the PH value greater than 5.5, iron content of not more than 15 mg / l, manganese content of no greater than 2.0 mg / l, after iron content in water is less than 0.3 mg / l, manganese content of less than 0.1 mg / l to meet "Life drinking water health standards".
Principle: the equipment to the natural manganese fine sand filter, the use of oxidants in the air, the ground water flow under outdated by oxidation of oxygen in the air and then after a period of time adequate response, the price of iron ions are oxidized into trivalent iron ions and precipitation . After re-flow filtration filters, filters natural manganese in filling sand. Manganese is the fine sand filter water from the oxidation of iron catalyst, but also will be three price precipitation separated from the water to processing requirements.
