Iron and Manganese Filter System Guard Equipment Running

Aeration. Raw water is pumped into the aeration tank through the pump. After two aeration (Impeller aeration and falling aeration), water and air fully mixed, part of the low-valent iron and manganese ions are oxidized into high-valent iron and manganese ions, generating part of the iron hydroxide and manganese oxide precipitates, while through the exhaust valve with the aeration tank air pressure and water pressure changes intermittently from the exhaust port discharge CO₂ exhaust gas, so that the dissolved oxygen water pH alkaline (in addition to iron and manganese need to be carried out in alkaline water).

Filter & Backwash. The dissolved oxygen water fully mixed with oxygen enters the filter tank and flows through the natural manganese sand layer. Under the catalytic effect of manganese sand, divalent iron and manganese ions are oxidized to high valent iron and manganese ions and hydroxide precipitates are generated, and clean water is obtained by the filtering effect of manganese sand. Through the backwashing function of the filter valve, the hydroxide precipitates and impurities in the manganese sand are discharged from the filter tank by regular backwashing.
