Anthracite filter material use
Anthracite filter material is widely used in chemical industry, metallurgy, thermal power, pharmaceutical, paper, printing and dyeing, food and so on before and after the production of water treatment process. Anthracite filter material is a kind of widely used best filter material, with quartz sand filter material with the use of the current promotion of the double rapid filter and three layer filter, filter tank filter common form.
Anthracite filter material in the filtering process of the role of a direct impact on the filtration of water quality, so the choice of this filter must meet the following requirements:
1, high mechanical strength, crushing rate and wear rate and should not be greater than 3% (by weight).
2, stable chemical properties, does not contain toxic and harmful substances. In general acid, alkaline, neutral water are not dissolved. Our factory products by the China water treatment media supervision and test center measured: hydrochloric acid soluble rate was 0.98% (ministerial standard of 3.5) in all kinds of water can reach a good purification effect.
3, particle size distribution is reasonable, specific surface area, there are edges and corners, gloss is good, three times by mechanical vibration screening, grading conform to the relevant technical indicators.
4, the particle size range is less than the specified minimum size by weight of not more than 3%, greater than the specified maximum size by weight of not more than 2%.
