With the development of environmentally friendly form, evolved into the darling of the times. Manganese sand filter to type complete its selling diversified development to meet the market. In environmental management occupies an important position. In recent years, as the country's rapid development of environmental protection, the level of manganese sand filter technology continue to improve, manganese sand filter innovative technology has become the industry's preferred way to promote their development. Due to the current filter the increasingly fierce market competition, emphasis on innovation, improve intellectual property and value-added products into the international market within the manufacturing industry in the important weight of winning. The use of those who have special requirements on the density outside. Natural manganese sand filter hydrochloric acid soluble rate should not be greater than 3.5% (percentage by mass) each manganese sand supporting material thickness should be correct, uniform, with a shovel or scraper scraping appearance, it is close to the horizontal plane, height should match the pavement highly symbolic horizon. According to the above approach operations, such as the thickness of the filter is less than the value of delimitation should meet the requirements above operation is repeated until the stop. Manganese sand filter in Puwan 2 ~ 4mm manganese sand supporting material, the use of the filter cap scour scour strength to remove sediment supporting guessed. How to choose a groundwater treatment Manganese sand? NOTE: The quality manganese sand filter in the filter the water, affecting the filtered water, so to rigorous selection. Carefully check particle size is not the same supporting material, its diameter size, from largest to smallest sequentially washed to prepare pavement. Manganese sand filter water extract of the human body should not contain toxic and hazardous substances. After scouring scrape light material and less than the specified minimum size of the particles.
