Evoqua uses carbon to remove organic contaminants from water and vapor streams. Carbon adsorbers take advantage of molecular forces to treat contaminants.
When molecules or ions do not have all their molecular forces satisfied, they are “unsaturated.” Carbon particles can satisfy their molecular forces by attracting and holding compounds. This concentration of molecules on a solid surface is called adsorption.
Carbon adsorption occurs when organic compounds are selectively adsorbed onto the surface of carbon. When carbon is “activated,” usually by heating it with oxygen or steam, the carbon becomes more porous. The available surface area within an activated carbon particle is hundreds of square meters per gram. Inter-molecular attraction draws organic molecules to the porous surface of the carbon particles.
Carbon becomes spent when it is unable to adsorb any more contaminants. The spent carbon must then be replaced with fresh carbon. The spent carbon may be disposed of, or sent to a facility where the adsorbed molecules may be removed from the spent carbon. This process is called reactivation, and is usually done offsite at a reactivation facility, by applying heat.
