NATURAL ANTHRACITE ACTIVATED CARBON
Coal based granular activated carbon has unique advantages due to its high strength, well-developed pores, large specific surface area, and especially large microporous volume.
Coal based activated carbon has strong adsorption capacity for various organic matter, free chlorine in water, and harmful gases in the air. It is an excellent adsorbent for deep purification of urban drinking water and is applied to remove bacteria and toxic gases in the air. Coal based activated carbon has developed pore structure, good chemical stability, and mechanical strength, making it an excellent broad-spectrum carbon adsorption material.
Coal based granular activated carbon is mainly used for the purification of toxic gases, waste gas treatment, industrial and domestic water purification. It is suitable for the purification of raw water in power plants and tap water, especially in the filtration and purification of chemical wastewater and the chlorine treatment of brackish water in power plant boilers. It has a good treatment effect.

The main performance of coal based granular activated carbon is adsorption, which is related to the pore structure of activated carbon. The specific surface area and specific volume of micropores are both large. Therefore, micropores largely determine the adsorption capacity of activated carbon. On the surface of solid activated carbon, two main modes of adsorption occur, namely physical adsorption and chemical adsorption.
According to different uses, activated carbon can be divided into various uses such as water purification, air purification, decolorization, solvent recovery, injection, and protection. Due to its acid resistance, alkali resistance, heat resistance, and the convenient regeneration of granular activated carbon after adsorption saturation, activated carbon is an essential carbon adsorption material in modern industrial production and environmental protection.
Advantages:
1) The main characteristics of the application of coal based granular activated carbon are low equipment investment, low price, fast adsorption speed, and strong adaptability to short-term and sudden water pollution.
2) Adding coal based granular activated carbon has a significant effect on removing chromaticity. The removal of chromaticity has been reported to reach 70%, and low chromaticity indicates high efficiency in removing organic matter, as well as good removal of iron and manganese.
3) Adding coal based granular activated carbon has a significant effect on odor removal.
4) Adding coal based granular activated carbon helps to remove anionic detergents.
5) Adding coal based granular activated carbon helps to remove algae. The addition of coal based granular activated carbon blocks the light absorption of algae, and has a significant coagulation effect in low turbidity water sources, which helps to remove algae in coagulation sedimentation.
6) The addition of coal based granular activated carbon significantly reduces the chemical oxygen consumption and five day biochemical oxygen demand, which are positively correlated with the degree of organic pollution in water bodies, indicating the degree of removal of toxic and harmful substances in water bodies.
7) Adding coal based granular activated carbon has a good effect on the removal of phenols.
8) The addition of coal based granular activated carbon powder significantly reduces the turbidity of the effluent and improves the water quality of tap water.
9) The effect of adding coal based granular activated carbon on water mutagenicity can effectively remove organic pollutants. It is a simple and convenient way to improve drinking water quality through conventional processes.
