I produced the manganese sand filter is the use of domestic high-quality manganese placer, grain density, high mechanical strength, chemical activity, not broken, do not dissolve in water, natural manganese sand. After washing polishing cleaning, crushing, drying, magnetic election, screening, dust and other processing into sand. then processed by a certain manganese sand graded blending. It has the best water filter grading proportion, it has the largest volume in the unit The specific surface area, the strongest interception capability, the largest and smallest catalytic oxidation backwash churn. manganese sand filter appearance of dark brown, nearly round, the main ingredient is manganese dioxide content of 35% -45% between. use groundwater manganese sand filter process, the process is simple, easy operation, low cost and long-term stability, the service period of more than five years, easy to manage, without filling any chemicals to achieve removal of iron, manganese, The purpose arsenic and other harmful substances, water quality fully meet the national drinking water standards, it is a very good groundwater treatment filter.
