The refined anthracite filter material is made from Shanxi high-quality anthracite through selection, crushing and twice screening. It has good luster, spherical appearance, high mechanical strength, good compression resistance, stable chemical performance, no toxic substances, wear-resistant, insoluble in acid, neutral and alkaline water, and has a rough surface and good adsorption capacity, The porosity is large (>50%), with high contaminant capacity. Due to light weight, the required backwash intensity is low, which can save a lot of backwash water and power.
Same as anthracite filter material Quartz sand The combined use of filter materials is the current promotion of double-layer rapid filter, three-layer filter pot Better material for filtration. It is an effective way to increase the filtration rate, increase the water output per unit area, double the sewage interception capacity, reduce the project cost and reduce the floor area. It is widely used in water quality treatment before and after the production of chemical industry, metallurgy, thermoelectricity, pharmacy, paper making, printing and dyeing, food, etc.
Standard anthracite filter material
The standard anthracite filter material is made of high-quality carbon blocks through selection, crushing, screening and processing. It has good appearance gloss, multi prism particle shape, strong compression and wear resistance, and is generally used for double-layer and three-layer filtering.
TJP type anthracite filter material TJP type anthracite filter material is produced according to the standards of Japan Shuidao Jushi Association, and its quality fully meets the Japanese standards. It is mainly used for steel rolling circulating water treatment of iron and steel system and high-level treatment of petrochemical industry sewage. It is also suitable for advanced water filtration in accurate manufacturing, aerospace and navigation.
Common specifications: 0.8-1.2mm, 0.8-1.8mm, 1-2mm, 2-4mm, etc.
Anthracite filter material is a kind of filter material used in water treatment industry. Anthracite filter material is made of high-quality anthracite as raw material through the process of fine selection, crushing, powder, screening, etc. It is generally a double-layer, three-layer fast filter material. It is applicable to the purification treatment of general acidity and neutral alkalinity, with good specific surface area, and all indicators meet the standards of the Ministry of Construction (CJ/T44-1999). Anthracite filter material is specially selected from deep well minerals, with a high carbon content percentage. Anthracite filter material is classified manually, which can reduce irrelevant minerals and ash content. It is also filtered and washed to ensure that it is suitable for water filtration. Due to its good solid particle retention capacity, anthracite can reliably improve the removal capacity of suspended particles. In addition, its uniformity coefficient is low, which helps to speed up the flow velocity.

Anthracite filter material is currently widely used as a better filter material. The main ore source comes from Jincheng and Yangcheng coal fields in Shanxi. It has a wide range of applications. It can be used for drinking water, industrial production water and various types of ordinary fast filters. Double layer and three layer filters, various sewage filters, water purification mechanical filters, and water quality treatment before and after the production of chemical, metallurgical, thermoelectric, pharmaceutical, paper making, printing and dyeing, food, etc.
The function of anthracite filter media in the filtration process directly affects the filtered water quality, so the selection of filter media must meet the following requirements:
① The mechanical strength is high, and the sum of crushing rate and wear rate should not be more than 3% (percentage by mass).
② The chemical property is stable and does not contain toxic substances. It is insoluble in general acidic, alkaline and neutral water. The ex factory products are tested by China Water Treatment Filter Media Supervision and Testing Center: the solubility of hydrochloric acid is 0.68% (the ministerial standard is 3.5), which can achieve good purification effect in various water sources.
③ The particle size grading is reasonable and the specific surface area is large. The appearance of the product is spherical with edges and corners, and the gloss is good. After three times of screening by mechanical vibration, the grading meets the relevant technical indicators. The uniformity coefficient (K60) is not more than 1.5 (Japanese standard), the nonuniformity coefficient (K80) is between 1.6-2.0, and the porosity is more than 50%.
④ The particle size range less than * * * lower limit shall not be greater than 5% by weight, and the particle size greater than * * * upper limit shall not be greater than 5% by weight.
Refined anthracite filter material Anthracite filter material is a double-layer and three-layer fast filter material widely used at present, which has high mechanical strength, stable chemical properties, no toxic and harmful substances, is insoluble in general acidic, alkaline and neutral water, reasonable particle size grading, and good specific surface area. Its role in the filtering process directly affects the filtered water quality, All indicators meet the (CJ/T44-1999) standard
