I plant the production of anthracite filter media, the use of high-quality Hong Shanxi carbon as raw material selection, crushing, screening and other process from processing. Particle uniformity, gloss, compression wear, high mechanical strength, long life cycle, practical in general acid, in alkaline water purification treatment, is double, three water purification filter material indispensable , the technical indicators have reached and exceeded the Ministry of Construction (CJ/T44-1999) standards. 

 Anthracite Filter Media in the role of the filtering process directly affect the filtration of water, so the choice of filter media must meet the following requirements: 

 (1) high mechanical strength, fragmentation rate and the wear rate and should not exceed 3% (by weight). 

 (2) chemical stability, non-toxic and hazardous substances. In general acidic, alkaline, neutral water are not dissolved. I plant products determined by the China Center for :**** water soluble was 0.98% (ministerial standard 3.5) in the various types of water purification can achieve good results. 

 (3) size class with the management, than the surface area well. Appearance of the product was spherical and angular, gloss, mechanical vibration three times by screening, grading to meet the technical specifications. 

 (4) particle size range is less than the specified limit by weight not more than 3%, greater than the specified maximum size I weight less than 2%. 

 Media considerations and operational requirements filled 

 (1) before filling the filter will filter (filter) cleaned house. 

 (2) to lay evenly on each filter, calibrated thickness is reached, it must Baping filter. 

 (3) long-run media, there will be wear and tear. If improper operation will be "run stuff" happen. This is subject to regular inspection filter conditions, if any, loss of material circumstances, need to replenish. Such as the filter run time is too long, the long-term water quality is unclear, or considered turbostratic layer occurs, you need to replace or re-graded filter.
