Anthracite filter effect, Saatchi anthracite filter (certified), Chongming County anthracite filter

 Anthracite filter selection criteria: Anthracite in the role of the filtration process directly affect the quality of filtration, so the choice of this filter must meet the following requirements: ① high mechanical strength anthracite filter effect crushing rate and the rate of wear and should not exceed 3% (percentage by mass). ② chemically stable, non-toxic substances. In general acidic, alkaline, neutral water, not dissolved. Water filter products manufactured by the China Supervision and Testing Center measured: Hydrochloric acid soluble rate of 0.68% (ministerial standard 3.5) in all types of water sources can achieve good purification effect. ③ particle size with the management, large surface area. Product appearance of spherical and angular, gloss, three times by mechanical vibration screening, grading comply with the relevant technical specifications. Uniformity coefficient (K60) is not greater than 1.5 (Japanese standard), uniformity coefficient (K80) between 1.6-2.0, porosity greater than 50%. ④ particle size range smaller than the specified limit by weight not more than 5%, greater than the specified upper limit of particle size by weight of not more than 5%. Anthracite filter material selection criteria: Anthracite filter material in the filtering process action is good or bad, a direct impact on the filtered water quality, so the choice of this filter material must meet the following requirements: basic concepts of adsorption adsorption technology Anthracite classification separation operation: ① by force, depending on the nature of classification, the nature of the adsorption force between adsorbent and adsorbate can be divided into physical adsorption and chemisorption. Due to the physical adsorption and the adsorbed molecules interstitial adsorbent surface molecules caused by the presence of van der Waals forces, when the gravitational and surface molecules of the adsorbent adsorbate molecules is greater than the gravitational fluid phase intramolecular between adsorbate molecules are adsorbed in on a solid surface, which has become a van der Waals adsorption adsorption. Chemisorption known as active adsorption anthracite filter specifications, it is due to a chemical reaction occurs between the adsorbent and adsorbate and cause, the strength of the chemisorption bond depends on the size of the force between two molecules. The adsorption process is an exothermic process washed anthracite filter, as is usually much higher than the van der Waals bond strength, so much the heat of adsorption heat of adsorption heat of adsorption chemisorption than physical adsorption, physical adsorption heat of condensation on the value of the adsorbate rather, while the adsorption heat adsorbed chemically equivalent chemical reaction heat numerically.
