Anthracite Filter Media It is the best filter material commonly used at present, the same as Quartz sand The combined use of filter materials is the current promotion of double-layer rapid filter, three-layer filter pot Common forms of filtering. 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 the water treatment process before and after the production of chemical industry, metallurgy, thermoelectricity, pharmacy, paper making, printing and dyeing, food, etc.
Anthracite Filter Media Product details:
Anthracite Filter Media It is a kind of filter material for water treatment industry. Anthracite Filter Media It uses high-quality anthracite as raw material, and is processed through the process of fine selection, crushing, powder, screening, etc. It is generally a double-layer, three-layer fast filtering 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 Media It is specially selected from deep well minerals with 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.
Refined anthracite filter material Shanxi high-quality anthracite is used as raw material, which has been carefully selected, crushed, and screened twice. It has good luster, spherical shape, high mechanical strength, good compression resistance, stable chemical performance, no toxic substances, abrasion resistance, and is insoluble in acidic, neutral, and alkaline water. In addition, anthracite particles have rough surface, good adsorption capacity, and large porosity (>50%), It has a high contaminant capacity. Due to its light weight, the required backwash intensity is low, which can save a lot of backwash water and power.
Anthracite Filter Media The role played in the filtration process directly affects the filtered water quality, so the selection of filter materials must meet the following requirements:
1. The mechanical strength is high, and the sum of crushing rate and wear rate shall not be greater than 3% (by weight).
2. Stable chemical performance, free of toxic and harmful substances. It is insoluble in general acidic, alkaline and neutral water. The products of our factory have been tested by China Water Treatment Filter Media Supervision and Testing Center: the solubility of hydrochloric acid is 0.98% (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 good. 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.
4. The particle size range less than * * * lower limit shall not be greater than 3% by weight, and the particle size greater than * * * upper limit shall not be greater than 2% by weight.
1、 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.

Precautions and operation requirements for filter material filling
1. The filter tank (filter) must be cleaned before filling with filter materials.
2. Be even Floor paving Each layer of filter material shall be set. When it reaches the calibrated thickness, the filter material must be raked.
3. The filter material will be worn after long-term operation. If the operation is improper, "material leakage" may occur. For this reason, it is necessary to regularly check the condition of filter materials, and timely supplement if there is any material shortage. If the filter material has been running for a long time, the effluent quality is not clear for a long time, or the filter layer is disordered, the filter material needs to be replaced or re graded.
