Manganese agent is a kind of mineral. It is used in water treatment industry to remove iron and manganese. Therefore, it is often called iron remover, manganese remover, etc. It is used in drinking water, groundwater, hot spring water, Bath water and other water quality is widely popular in removing iron and manganese. So, what is the principle of manganese removal?

The appearance of the manganese agent is reddish-brown or dark-brown, nearly round, the main component is manganese dioxide, and the content of MnO2, which can remove iron and manganese, is more than 30%. This kind of manganese agent has the characteristics of good quality, dense grain, high mechanical strength, not easily broken, insoluble in water, low ash, long service life, convenient backwashing, stable performance and so on. At present, the content of manganese dioxide MnO2 produced by our factory is mainly divided into four grades: 45%≤MnO2<40%, 40%≤MnO2≤35%, 35%.

Manganese agent has the ideal gradation ratio of water treatment filter media, so that it has a large specific surface area, strong pollution interception capacity, large oxidation catalysis and small backwash loss rate per unit volume. Manganese purification material.
