Manganese Sand Filter

  • Description
Product Detail

Most areas of groundwater containing Tieda 5 ~ 15mg/L, up to 20 ~ 39 mg/L, manganese content was 0.5 ~ 2.0mg/L, even more than 2 mg/L. Iron exists in the Fe2+ state of the groundwater exceed the standard, so just pumped, water is clear and clean, but the smell of iron. For a long time, the quality of the water becomes turbid. Fe2+ very easy to pollute the ion exchange resin, so that the resin poisoning and reduce the exchange capacity. Fe2+ causes the reverse osmosis membrane to be contaminated and failed. When the water is supplied by the boiler with hot metal, it is easy to fouling, which not only affects the heat transfer, but also can easily lead to tube wall corrosion. When the amount of iron in the cooling water exceeds 0.5mg/L, iron will cause the iron bacteria to propagate, the sticky mud produced in addition to the pipeline will be blocked, but also to accelerate the corrosion of equipment. In addition to iron and manganese filter built in natural manganese sand containing high manganese can Fe2+ oxidation of Fe3+, while the formation of manganese sand filter layer surface active membrane, can further improve the removal of iron, set the process of oxidation, ion replacement, rejection and clarification, according to customer's water quality to make reasonable design process, to achieve reliable and stable effect.
