In some natural manganese sand filter, the filter layer upper portion of manganese sand will gradually form a spherical "rust sand", "rust sand" surface layer "active membrane" the proportion of manganese sand filter density, still has contact with catalytic except iron capacity, so the formation of "iron ore" is not a sign of failure of natural manganese sand. Manganese sand filter is chosen dense grain density not broken, high mechanical strength, high compressive strength, excellent high manganese content of manganese sand finishing. Develop investment and financing environment, cleaner production audits, certification assessment, environmental insurance, environmental litigation and education and training, environmental services system, to explore new service models. Focus on R & D and demonstration manganese sand filter membrane materials and membrane modules, high performance impermeable material, high-fiber filter baghouse and accessories; promotion of ion exchange resins, biological filter and a filler, such as activated carbon efficient. Environmentally friendly materials. When the "rust sand" grow resulting filter size is too thick and iron in addition to the effect of the impact, it become necessary to replace the media sector. So, in our construction process should pay attention to whether there is "rust sand" exists, if any, must distinguish clearly "rust sand" in size, if it is small size, can be inherited use, you can reduce the cost of our industry , if it is a large size, it is necessary to replace, so as not to affect water filtration. Manganese sand filter is often used for drinking water, industrial water recycling in addition to iron, manganese filter. Manganese sand filter works: iron to Fe2 + state had underground (well) water, the water has heterochromatic odor, pollution of ion exchange resin and lower exchange capacity, acquired a long iron scale, affecting heat transfer, can erode equipment . MnO2 manganese sands and Fe2 + redox reaction, the Fe2 + into Fe3 + and natural Fe (OH) 3 precipitate, which use manganese sand filter backwash function to achieve the purpose of the removal of purification. High Manganese sand filter is a strong oxidant manganese sand manganese oxidation, can play in water oxidation of divalent iron manganese sand, manganese sand filter commonly used in drinking water in addition to iron, and manganese filter, except groundwater iron and manganese from water purification to use. I plant produced manganese sand filter is the best at home in addition to iron and manganese filter, its manganese dioxide content of more than 30%, high mechanical strength, chemical chaos is good, long service life of iron and manganese in addition to 35% manganese sand effect, welcomed by users. Sewage. Manganese sand filter is the use of domestic quality, grain density, mechanical strength, chemical activity, not broken, do not dissolve in water, natural manganese ore. It has the best water filter grading proportion, it has the largest volume per unit of surface area, the strongest interception capability, the largest and smallest catalytic oxidation backwash churn. And then processed by a certain manganese sand graded blending. Manganese sand filter Common Specifications: 0.25-0.5mm 0.5-0.8mm 0.8-2.0mm 1.0-2.0mm 2.0-4.0mm 4.0-8.0mm 8.0-16mm high manganese content in the manganese dioxide means more than 30% of manganese sand filter material, which is mainly used in drinking water treatment water plant. Treatment of water. After washing polishing cleaning, drying, magnetic separation, screening, dust and other process into sand. Low manganese dioxide manganese content refers to 30% or less of manganese sand filter, which is mainly used in industrial water use. It has the best water filter grading proportion, it has the largest volume per unit of surface area, the strongest interception capability, the largest and smallest catalytic oxidation backwash churn. Only 30% of manganese sand iron, Song Xin filter manganese sand filter, manganese sand provided by the Qingpu District Gongyi City Song Xin Industrial Co., Ltd. filter. Filter Gongyi City Song Xin Industrial Co., Ltd. (www.sxlc.com) quality of service and products, continue to receive the recognition and trust of new and old customers and the industry.
