Biqing water free samples, technical support, service tracking, your satisfaction, my pleasure ......... high activated carbon intensity, developed porosity, large surface area, pore volume, especially large and unique advantages. Coal activated carbon organic matter of various water, free chlorine and harmful gas in the air has a very strong adsorption capacity, is an excellent adsorbent urban drinking water purification, and applied to the removal of airborne bacteria and toxic gases. Activated carbon from coal has developed pore structure, good chemical stability and mechanical strength, it is a good broad spectrum carbon adsorbent material. Depending on the appearance of forms, it can be divided into coal quality activated carbon from coal granular activated carbon and coal quality powdered activated carbon, granular activated carbon is divided into forming carbon QUALITY [including columnar charcoal, charcoal briquettes (or tabletting charcoal) and spherical carbon and coal crushing activated carbon into two categories. Depending on the application, it can be divided into water purification, air purification, bleach, solvent recovery, multi-purpose use of activated carbon injection, with an equal protection. Because of its acid, alkali, heat, and granular activated carbon adsorption after saturated, can be easily regenerated, so, activated carbon is the modern industrial production and environmental protection in society essential carbonaceous adsorbent material. QUALITY granular activated carbon adsorption of solute molecules is a complex process that is combined result of several forces, including ionic attraction, Van der Waals forces, miscellaneous chemical and power. The dual diffusion rate adsorption theory that that is done by adsorption is a rapid diffusion and slow diffusion of two-speed two-stage process consisting spread rapidly within a few hours, played adsorption capacity of 60% to 80% of coal quality granular activated carbon. The rapid spread of solute molecules in the process of soot little resistance along large pores uniformly distributed in radial diffusion. These large pores produce radial diffusion resistance. When molecules from large holes further into the large hole communicating micropores diffusion, due to the great resistance generated by the narrow aperture, which is extremely slow. It is uniformly distributed in the porous carbon particles, but do not constitute a radial diffusion resistance. Factors affecting coal quality granular activated carbon adsorption of solute molecules involved in polarity, molecular size, spatial structure, which depends on water quality characteristics. QUALITY granular activated carbon for different substances molecule having selective adsorption. Advantages of activated carbon from coal 1) the main features of the application is granular activated carbon coal quality equipment investment, cheaper prices, fast absorption, short-term and sudden water pollution adaptability. 2) adding coal quality granular activated carbon for the removal of color have a significant effect. Removing the color has been reported up to 70%, low chroma showed high removal efficiency of organic matter, good effect of iron and manganese removal. 3) adding coal quality granular activated carbon for the removal of smell have a significant effect. 4) adding coal quality granular activated carbon to help remove anionic detergent.
