Activated carbon adsorption is a process used to remove impurities from water and air by using activated carbon as an adsorbent material. Activated carbon is made from high carbon content materials such as coal, coconut shells, wood, or other organic materials that are processed to produce a porous carbon structure. The activated carbon has a large surface area that enables it to adsorb impurities and contaminants from water and air.
When water or air is passed through a bed of activated carbon, the impurities and contaminants present in it get adsorbed on the surface of the carbon particles. The activated carbon has a high affinity for organic compounds, including volatile organic compounds (VOCs), pesticides, herbicides, and other chemicals. It also removes chlorine, sediments, and unpleasant odors from water.
