what is the differences of anthracite coal and activated carbon ? How to distinguish activated carbon and anthracite coal

Many customers know that both anthracite filter media and coal-based activated carbon can purify water, but what are the differences between them?

      1. Different production techniques

      Anthracite filter material is made of high-quality anthracite as raw material, which is selected, crushed, and screened twice. It has a glossy and non-toxic appearance, good pressure resistance, and stable chemical properties.

      Coal-based activated carbon uses high-quality coal as raw material and is innovatively produced through a series of processes including carbonization → cooling → activation → washing.

 2,different mechanisms of action

The principle of anthracite filter material water purification is as follows: liquid containing impurities flows through a filter medium with a certain porosity, and the impurities in the liquid are trapped on the surface or inside of the medium and removed.

      Principle of coal-based activated carbon water purification: Activated carbon is a very small carbon particle with a large surface area, and there are even smaller holes-capillaries in the carbon particles. This kind of capillary has strong adsorption capacity. Because the surface area of the carbon particles is large, it can fully contact with impurities. When these impurities hit the capillary, they are adsorbed and play a purifying role.

3, different scopes of application

      Anthracite filter media is widely used in the water quality treatment process before and after supply in chemical industry, metallurgy, thermoelectricity, pharmaceuticals, papermaking, printing and dyeing, food, etc.

      Coal-based activated carbon is widely used in various aspects of industrial and agricultural supply: 1. Alkali-free deodorization (refined demercaptan), ethylene desalted water (refined filler), catalyst carrier (palladium, platinum, rhodium, etc.), water purification and sewage in the petrochemical industry Treatment; 2. Water quality treatment and protection of power enterprises in the electric power industry; 3. Chemical catalysts and carriers, gas purification, solvent recovery and decolorization and refining of oils and greases in the chemical industry; 4. Beverages, alcoholic beverages, MSG mother liquor and Refining and decolorizing food; 5. Gold extraction and tail liquid recovery in the gold industry; 6. Wastewater treatment, waste gas and harmful gas control, and gas purification in the industry; 7. Cigarette filters and wooden floors in related industries to prevent moisture and odor absorption. , automobile gasoline evaporation pollution control, preparation of various impregnating agent liquids, etc.

     Anthracite filter material has low raw material price and simple production process, and is suitable for water treatment; while coal-based activated carbon has low raw material price, but the production process is more complicated. It can be used not only for water purification, but also for waste gas treatment and solvent recovery, and has a wide range of applications. .

How to distinguish coal-based granular activated carbon and anthracite filter media (coal )?

1. Put these two products into the water, and then look at the bubbles in the water. The more bubbles one is activated carbon. If there are few bubbles or no bubbles ,it is anthracite.

2,3. check the bulk density. The lighter one must be activated carbon. Since the bulk density of anthracite is 900kg/CBM.
