Manganese sand filter is the use of domestic quality, grain density, mechanical strength, chemical live strong, not broken, do not dissolve in water, natural manganese ore. After washing polishing cleaning, drying, magnetic separation, screening, dust and other technology into the sand. Manganese sand then processed by a certain gradation blending. It has a water filter ideal grading scale, it has the largest volume in the unit specific surface area, the strongest interception capacity of the largest and smallest catalytic oxidation backwash churn. Manganese sand filter appearance of rough brown or light gray, commonly used in drinking water in addition to iron, manganese filters, water treatment effect is very good. (Note: MnO2 ≥ 35% either in addition to iron, but also manganese, MnO2 ≤ 30%) can only be used for groundwater in addition to iron) manganese sand filter mainly used to reduce the water content of iron and manganese, ferromanganese total, according to China drinking water standard gauge its iron content ≤ 0.3 mg / L, Mn ≤ 0.1 mg / L, iron manganese content is too high for a long time drinking water will seriously affect the health of the North Branch company is the production of drinking water filtration One of the earliest manufacturers materials industry, the company advanced technology, well-equipped, strong technical force, combined with modern scientific management methods, producing more than ten kinds of products, hundreds of specifications, the main products: efficient water purifying agent series - Chlorinated polymerization aluminum composite polymeric ferric chloride, aluminum chloride, etc.. Filter series - manganese sand filter (iron and manganese), magnetite media, Nutshell filter (degreasing), quartz sand, anthracite filter, ceramic filter (light, heavy ), shale ceramic filter, rare earth porcelain sand filter, activated carbon filter a variety of models, inert alumina ceramic ball filter, various types of white, variegated cushion gravel (gravel) filter, foam particles filter beads fillers, garnet filter and so on. New plastic packing series - multi-faceted hollow ball, fiber ball, cover the ball surface, Pall rings, ladder rings, water treatment apparatus, co-HF inclined tube filler materials such as water purification. The product is by the Chinese media Testing Center, Harbin Institute of Technology built identification, iron and manganese removal of groundwater Determination Association, the National Institute of Electric Power Industry Bureau thermal test, the technical indicators have reached and exceeded the Ministry of Construction ministerial standards (CJ / T43-1999 and CJ/T44-1999). Petroleum, chemical, electric power, metallurgy, environmental protection, printing and dyeing, paper, water treatment and other industries ideal for purifying fish, it was adapted to single, double and triple filter, valveless and siphon filter and the kind of mechanical filter, from switches and so on. My company to new and old customers sincere love, courage, innovation and enterprise, the quality of survival, reputation and development, to be effective management approach and dedication to customer service, welcome to the North Branch of green cleaning advice!
