1、 Introduction:
Anthracite filter material is made from high-quality raw coal, which is carefully selected, crushed, and screened twice. It has a good appearance luster, spherical shape, high mechanical strength, good compressive performance, stable chemical properties, does not contain toxic substances, is wear-resistant, and does not dissolve in acidic, neutral, or alkaline water. In addition, the surface of anthracite particles is rough, with good adsorption capacity, high porosity (≥ 52%), and high pollution capacity. Due to its light weight, the required backwash strength is low, which can save a lot of backwash water and electricity.
2、 Application:
Anthracite filter material is a type of filter material used in the water treatment industry. Anthracite filter material is made from high-quality anthracite as raw material, processed through selected crushing, powder, screening and other processes. It is commonly used as double-layer or three-layer rapid filtration material. Suitable for general acidic and neutral alkaline purification treatment, with good specific surface area and all indicators meeting the standards of the Ministry of Construction (CJ/T44-1999).
The combination of anthracite filter material and quartz sand filter material is the best material for double-layer rapid filter and three-layer filter and tank filtration promoted in China. It is the most effective way to increase the filtration rate, increase the water output per unit area, and double the sewage interception capacity, reduce project costs, and minimize land occupation. Widely used in water quality treatment processes before and after production in chemical, metallurgical, thermoelectric, pharmaceutical, papermaking, printing and dyeing, food, and other industries.
3、 Features:
Anthracite filter material is specially selected from deep well minerals and has the highest percentage of carbon content. Anthracite filter material is manually classified, which can reduce irrelevant minerals and lower ash content. It has also been filtered and rinsed. Anthracite filter material is specially selected from deep well minerals and has the highest percentage of carbon content. The water filter material adopts manual classification, which can reduce irrelevant minerals and lower ash content. The water filter material is also filtered and washed to ensure its suitability for water filtration. Due to its good solid particle retention ability, anthracite can reliably improve its ability to remove suspended particles. In addition, its uniformity coefficient is low, which helps to accelerate the flow velocity.
