Anthracite not alone, general and other water purification materials, such as quartz sand used in conjunction. Currently, China is currently using anthracite filter and widely used as a filter. Anthracite commonly known as "white coal", is the deepest coal rank coal. Is a water filtration materials industry. I produced anthracite filter (Standard: People's Republic of China urban construction industry standards (CJ / T43-2005) is the choice and quality of Shanxi Jincheng Anthracite Mining Jiaozuo two as raw material crushing, screening, washing and processing. . to Anthracite filter characteristics are: high fixed carbon content, density, high strength, good appearance gloss, chemical stability, and has good ability to maintain solid particles, suspended particles can reliably improve the removal of anthracite filter does. containing toxic and hazardous substances, in acidic, neutral water, not dissolved. Anthracite Anthracite compression wear resistance, there is enough surface area and particle size gradation reasonable due Anthracite has good solid particle retention capacity, it can reliably improve suspended particles scavenging anthracite filter suitable for drinking water and industrial water filtration Anthracite technical requirements: 1, broken rate and the wear rate of the anthracite media and should not be more than 3% (percentage by mass, the same below). 2, the average density of anthracite filter is generally not less than 1.4g / cm3, not more than 1.6g / cm3. 3, anthracite filter should be free of visible dirt, shale and foreign debris. anthracite clay content should not exceed 3%, greater than the density of the material content of 1.8g / cm3 should not exceed 8%. 4, Anthracite hydrochloric acid soluble rate should not exceed 3.5% of the grain anthracite filter Diameter: 1, anthracite filter size range for drinking water is: 0.8-1.2mm, 1.2-2mm; industrial water Anthracite particle size ranges: 1-2mm, 2-4mm, 4-6mm 2, in a variety of particle size in the range of anthracite, particle size less than the specified limit should not exceed 3%, greater than the prescribed maximum particle size should not exceed 2%. The new Prime Anthracite Shengshi media is a kind of water treatment industry filter with filter, using Shanxi anthracite as the raw material, after selection, crushing and screening and two appearance, good luster, spherical, high mechanical strength, good compression resistance, chemical stability, do notcontain toxic substance Prime anthracite filter, abrasion resistance Anthracite filter effect, acid, in neutral, alkaline not dissolve in water, in addition to coal particle surface roughness anthracite filter specifications, have good adsorption capacity, high porosity (> 50%), a higher content of dirt ability, because the light, required backwash low strength, can save a lot of backwash water and electricity Anthracite cheap | Seoul Anthracite | fine anthracite filter water purification materials provided by Henan Spirit Limited. Henan Spirit Water Material Co. (www.gyssjs.com) strong, credible, in Zhengzhou, Henan water treatment chemicals and other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the Spirit into the brilliant water and you work for a better future!
