Product Description
The manganese sand filter material is made of high-quality natural manganese ore. It has a brown appearance and has a unique effect on removing iron and manganese from groundwater.
The appearance of the manganese sand filter is dark brown, nearly round, the main component is manganese dioxide, and the content is between 35%-45%
Manganese sand filter material is used to treat groundwater. The process is simple, easy to operate, low engineering cost, long-term stability, service cycle of more than 5 years, easy to manage, can be used to remove harmful iron, manganese, arsenic, etc. the water quality fully meets the national drinking water standards, and it is a very good groundwater treatment filter material.

Natural manganese sand is a strong oxidant, which can oxidize divalent iron in water. It is often used in drinking water removal iron and manganese filtration devices, and groundwater removal iron and manganese removal water purification equipment.
The service life of manganese sand is generally 3 to 5 years for groundwater with high iron concentration, and for groundwater with low iron concentration, the service life is longer, and some have more than ten years. In some natural manganese sand filters, the manganese sand on the upper part of the filter layer will gradually form spherical "rust sand", and the surface of the "rust sand" has a layer of "active filter membrane", which still has the ability to contact catalytic iron removal, so the formation "Rust sand" is not a sign of failure of natural manganese sand. When the length of "rust sand" roughly makes the particle size of the filter material too coarse and affects the effect of iron removal, it is necessary to replace part of the filter material. Therefore, we must pay attention to whether there is "rust sand" in our construction process. If so, we must distinguish the size of "rust sand". If it is a small size, it can continue to be used, which can reduce our industrial costs. , If it is a large specification, it must be replaced to avoid affecting the filtered water quality.
