Granular activated carbons are mostly made from Coconut Shells on petroleum coke, bituminous coal or lignite. Granular activated carbon is used in continuous process in areas like water treatment (drinking & effluent water), removal of mercury from effluents or alkali cells, solvent recovery, gold recovery, removal of odor, gas masks, as catalyst carrier, for dechlorination of water, purification & separation of gases, kitchen hoods, dry cleaning etc.
Coconut shell activated carbon, made from coconut husk, is a vapor-activated material. As this carbon contains no chemical agent, when utilized on a medium, it wont contaminate or respond with it. Its anything but an absolutely normal and harmless to the ecosystem item, that has a little carbon impression and can efficiently absorb impurities with micro-pore molecular structure, for example, those present in drinking water. Coconut shell activated carbon, owing to its high abrasion resistance and unique physical and chemical characteristics, can safely support applications such as the recovery of gold and other precious metals.
