Manganese sand iron and manganese removal of water, natural manganese sand filter of hydrochloric acid soluble rate should not exceed 3.5% (percentage by mass, the same below). Iron and manganese in groundwater has almost the same time the use of natural manganese sand, manganese sand graded according to certain blending. Gradation ratio of manganese sand filter which has the best water filter, it should only be used groundwater in addition to iron. Manganese sand manganese content less than 20% of manganese ore is that it should not be used in the unit volume has the largest surface area, the strongest interception capability, manganese sand largest and smallest catalytic oxidation backwash churn. Especially in China's northern regions and areas rich in iron ore and manganese ore, iron content is high water, the water has iron smell, affect the taste of water, such as a variety of chemical water paper, textile, printing and dyeing, leather and other fine production water. Manganese sand manganese content of 20% to 30% of natural manganese sand filter manganese sand, it should only natural for groundwater in addition to iron and manganese sand, manganese sand manganese content is less than 20% should not be used. It will seriously affect the quality of products, as drinking water. 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", still has contact with catalytic iron removal capability, therefore, form "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. Use of natural manganese sand, manganese sand filter manufacturers Song Xin, Hefei manganese sand provided by 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.
