Availability Limitations

This process is used to treat single-phase aqueous organic wastes with high molecular weight and boiling point, and low solubility and polarity; chlorinated hydrocarbons such as tetrachloroethylene; and aromatics such as phenol. It is also used to capture volatile organics in gaseous mixtures. Limitations are economic, relating to how rapidly the carbon becomes spent. As an informal guide, concentrations should be less than 10,000 ppm; suspended solids less than 50 ppm; and dissolved inorganics, oil, and grease less than 10 ppm.

Status. Conventional, demonstrated.
