Biqing water samples, technical free support, service tracking, your satisfaction, my pleasure ...... coal columnar activated carbon price function: the appearance of dark black columnar activated carbon particles or unshaped granular, with a large surface area, suitable gap structure, institutional strength high, can withstand high temperature, high pressure, easily broken, long service life. Coal granular activated carbon adsorption of solute molecules is a complex process that is the result of the combined effect of several forces, including ionic attraction, van der Waals forces, and miscellaneous chemical force. Double the rate of diffusion according to the adsorption theory that is a complete adsorption by the rapid spread and slow diffusion constitute two-speed two-stage process, the rapid spread within hours, played an adsorption capacity of 60% to 80% of granular activated carbon from coal. Rapid diffusion of solute molecules in the carbon granules little resistance along the process of large pores uniformly distributed in radial diffusion. These large pores produce radial diffusion resistance. When molecules from large hole further into the hole communicating with the large pore diffusion, the great resistance generated due to the narrow aperture and thus very slow. Is uniformly distributed within the porous carbon granules, but does not constitute a radial diffusion resistance. Factors Affecting Coal granular activated carbon adsorption of solute molecules involved in polarity, molecular size, spatial structure, which depends on water quality characteristics. Coal granular activated carbon molecules with different substances selective adsorption. The main features of the advantages of 1) the application of granular activated carbon from coal is equipment investment, cheaper prices, absorption speed, short-term and sudden water pollution adaptability. 2) adding granular activated carbon from coal has a significant effect on the removal of color. Chroma removal has been reported up to 70% lower color show high removal efficiency of organic matter, good effect of iron, manganese removal.
