How to deal with excessive iron and manganese in groundwater?

Many areas use groundwater as a source of water, if the content of iron and manganese in the water is too high, it will have a certain impact on our production and life. If yellow spots are left on white fabrics or water utensils or sanitary utensils; In industry, when used in textile, printing and dyeing, knitting, paper and other industries, it will affect product quality. So how do we deal with this situation?
When this happens, we usually use a manganese sand filter to remove the iron and manganese ions. Using the catalytic action of manganese sand, when the water flows through the manganese sand filter layer, due to the chemical action of the filter material, the iron and manganese ions in the water begin to oxidize, so that the trivalent iron ions in the water form an active oxide film containing crystal water on its surface, relying on the physical adsorption, the purpose of reducing the iron ion content in the water has been achieved.
According to the determination, when the iron content in water is 0.5mg/L, the chroma can reach more than 30 degrees, and when it reaches 1.0mg/L, not only the chroma increases, but also the obvious metallic taste. So in life if we encounter this problem, do not panic, install a manganese sand filter can be a good solution.
