What is anthracite filter material?
The anthracite filter material is made from high-quality anthracite with high carbon and low ash content, processed through processes such as crushing, screening, and cleaning. It has uniform particles, high hardness, and strong wear resistance, and has the following significant characteristics:
- Good chemical stability: acid and alkali resistant, insoluble in water, long-term use does not release harmful substances;
- Strong adsorption capacity: The surface microporous structure can effectively intercept suspended solids, colloids, and some organic matter;
-High backwashing efficiency: moderate specific gravity (1.4~1.6g/cm ³), easy to layer, superior regeneration performance;
- Long service life: High mechanical strength (wear rate<1%), not easily powdering, low maintenance cost.
Core application scenarios
Anthracite filter material, with its unique advantages, is widely used in the following fields:
1)Drinking water treatment
As the top filter material of a multi-layer filter, it efficiently intercepts impurities such as sediment, algae, rust, etc., ensuring clear and safe effluent.
2) Industrial wastewater treatment
Used for pre-treatment systems in industries such as petrochemicals, printing and dyeing, electroplating, etc., to reduce turbidity and COD load.
3)Swimming pool circulating water system
Quickly filter suspended particles to improve water quality transparency and hygiene standards.
4)Pre treatment of seawater desalination
Resist high salt corrosion environment and protect the stable operation of subsequent membrane systems.
Synergistic Enhancement of Anthracite Filter Media and Activated Carbon
In water treatment processes, anthracite filter media is often combined with granular activated carbon to form a "two-stage filtration system", achieving deep synergy between physical interception and chemical adsorption:
- Level 1: Anthracite filter material
Quickly remove large suspended particles and colloids to reduce subsequent processing load;
- Level 2: Activated carbon filter material
Absorb soluble organic matter, odors, residual chlorine, and trace pollutants to enhance water quality, taste, and safety.
> Technical advantage: This system balances efficiency and economy, significantly extending the service life of activated carbon and reducing operating costs.
