Activated carbon (Activated carbon)

Activated carbon
The production process of activated carbon can be divided into two procedures: carbonization and activation.

Carbonization is a process in which the material is turned into porous carbon structure through pyrolysisunder conditions of lacking oxygen and between temperatures from 300-500. During this process most non-carbon elements like oxyhydrogen will be eliminated as volatile gas. The combination of carbon atom-aromatic foliated structurewill have cracks because of its irregularity and these cracks will form more complicated holes when activated
Theory:
Activated carbon is to oxidize coconut shells, charcoal, wood or coal into particles with many holes under high temperatures. The hole is wide on the surface while become narrower as it deepens. It is about several angstrom to thousands of angstrom in width. Every one 1kg activated carbon has hole area totaling 1,500 square meter. These holes are the only access for activated carbon to adsorb chemicals and organic matters. Adsorption and absorption, though one letter different in spelling, has two different functions. Absorption is to adhere impurity to the surface of the activated carbon. The two has no chemical reactions. And after several activations, it become not sticky and needs to be changed.
In addition to minerals like Fe, water still contains other dissolvable organic compound. Many industrial used chemical raw materials or by-products will be thrown into river or underground water without any process to protect the environment. These various industrial wastes finally flow to and become the source of our drinking water. To detect the organic substance from the chemical compound is not easy at all. But adsorption is particularly useful in distinguishing organic matters and chemicals that dissolve in water. The typical adsorbent matter is activated carbon
1. Remove impurity in electroplate liquid and disposal of electroplate waste water.
2. Refinning and discoloring of edible oil, dyer, and medicine and running water.
3. Process additives of sewage, better results if used with organism processing equipment.
