Activated carbon is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions. Adsorption is a process where a solid is used for removing a soluble substance from the water. In this process, active carbon is solid. Usually, activated carbon is extracted from charcoal. Activated carbon is used to purify liquids and gases in various applications including municipal drinking water, food and beverage processing, odor removal, and industrial pollution control.
