Description: anthracite filter media is the best filter materials commonly used, in conjunction with the quartz sand is the promotion of China's current fast filter and three-layer filter, filter tank common form of filtering. Is to improve the filtration rate per unit area increases exponentially increase the interception capacity of water and reduce the project cost and most effective way to reduce the footprint. 

 Application: can be used for drinking water and industrial process water and various types of common pool filter quickly. Double and triple filter, a variety of water filters, water filters and chemical machinery, metallurgy, thermal power, pharmaceutical, paper, printing and dyeing, food production before and after water treatment. 

 Uses: Health, including water and industrial water purification filter. Widely used in chemical, metallurgy, thermal power, pharmaceutical, paper, printing and dyeing, food production before and after the water treatment process. 

 Characteristics: high mechanical strength, chemical stability, non-toxic and hazardous substances, specific surface area is good. 

 Anthracite filter media of the technical requirements: 

 1, anthracite filter media fragmentation rate and the wear rate and should not exceed 3% (percentage by mass, the same below.) 

 2, anthracite filter media, the average density is generally not less than 1.4g/cm3, no more than 1.6g/cm3. 

 3, anthracite filter media should not contain visible dirt, shale, and foreign debris. Clay content should not exceed 3%, the material density greater than 1.8g/cm3 content should not exceed 8%. 

 4, anthracite filter media of the soluble rate should not exceed 3.5%. 

 Anthracite filter media particle size: 

 1 filter for drinking water in the anthracite particle size range :0.8-1 .2 mm ,1.2-2mm; industrial water filter particle size range of anthracite :1-2mm ,2-4mm ,4-6mm. 

 2, in a variety of anthracite filter media in the size range, less than the specified minimum size should not exceed 3%, greater than the specified maximum size should not exceed 2%.
