Ningxia Baiyun supply a variety of coal-based, impregnated activated carbon, in standard and custom sizes, for applications where non-treated carbon may not be effective.Surface impregnation chemically modifies activated carbon through a fine distribution of chemicals and metal particles on the internal surfaces of its pores. This greatly enhances the carbon’s adsorptive capacity through a synergism between the chemicals and the carbon. And provides a cost-effective way to remove impurities from gas streams which would otherwise not be possible.
WATER TREATMENT
Because of its antimicrobial/antiseptic properties, silver-impregnated carbon is an effective adsorbent for purification in earth-bound domestic and other water systems.
GAS PURIFICATION
Impregnated activated carbon is used to treat flue gases in coal-fired generation plants and other air pollution control applications. Carbon can be specifically impregnated for removal of acid gases, ammonia and amines, aldehydes, radio-active iodine, mercury and inorganic gases such as arsine and phosphine. Carbon impregnated with metal-oxide targets inorganic gases including HCN, H2S, phosphine and arsine.
