Coconut Shell Powder Activated Carbon
Powder activated carbon is made from coconut shell, sawdust, coal or anthracite.
Specific surface area of ctivated carbon powder is much larger than activated carhon granules.
Large surface area and holes on activated carbon powder is also the reason why it is as carrier for many catalysts, and generally used in the chemical industry. Besides these, because of the character, it is also necessary to water purifying, sewage disposal system, or recycling of waste water from the boilers in power station.
Powdered activated carbon is a very fine powder, with the majority passing through a 200 mesh sieve and the majority passing through a 325 mesh sieve. The size of the powder ranges from 1 to 150 μ Between m (approximately 40 on average μ m) ; Usually, the finer the carbon powder, the faster it adsorbs impurities. Powdered activated carbon is both an adsorbent and a decolorizer, and has very important applications in industries such as industrial wastewater, industrial exhaust gas, and food decolorization.

Powder activated carbon has good applications in treating sudden odors and industrial pollutants in water. When using powdered carbon, adsorption tests must be conducted based on the type and concentration of pollutants to be removed to determine the type of activated carbon and the required amount of powdered carbon. Before adding powdered carbon, it should be noted that the carbon powder should be made into a carbon slurry and evenly added to water. The longer the contact time, the better the pollution removal effect.
1.Filter cotton, as the element of purifier, is made from activated carbon powder.
2.In waterworks, activated carbon powder will be used in purification of water from river to absorb
chloride or remove alga or other macromolecule.
3.It is common in waterworks, no matter purifying the water for home, or produce mineral water.
4.Powdered activated carbon is commonly used for refinement of pharmaceutical industry.
5.For eflluent treatment in electronics or heavy industry, money invested for sewage disposal
system, which depends on activated carbon powder, is limited.
