Is the manganese sand filter really effective for getting iron from well water 10? The iron removal mechanism of manganese sand filter material is by contact oxidation method,Let the Fe 2 in the groundwater enter the manganese sand filter layer together with the dissolved oxygen,Under the contact catalytic action of manganese sand filter layer,Complete the oxidation and interception of Fe 2.In the early stages of filtering,Mainly based on adsorption and iron removal,After a while,The capacity of adsorption and iron removal of filter materials has gradually weakened,The iron content of water after filtration has an upward trend.Meanwhile,The surface of the filter material begins to generate an iron filter membrane with catalytic activity,But the contact oxidation capacity is small,Therefore, in the process of forming the filter membrane, the new filter material,At the same time, it has two functions: adsorption and iron removal and contact oxidation and iron removal.At the later stage, the active iron filter m
