The activated carbon used in water
Activated carbon is a great surface area, porous carbon structure. Classification of raw materials can be divided according to their coal activated carbon, wood charcoal, husk charcoal and bone charcoal; charcoal column can be divided according to their shape, crushed charcoal, activated carbon fibers and carbon powder. The main raw material of activated carbon coal, wood, shell and other carbon-rich organic material, formed by the activation of complex pore structure adsorption capacity. 20000nm pore radius greater than the large hole in the hole between 150-20000nm is less than 150nm of micropores. Activated carbon adsorption occurs mainly in these voids and surface, activated carbon pore walls of a large number of molecules can produce strong gravitational water and impurities in the air to attract the pores.
