Reducing the level of dissolved organic carbon is an increasingly important goal in the treatment of drinking water. Dissolved organic carbon (DOC) compounds react with chemical disinfectants to form undesirable by-products, and DOC provides a substrate for bacterial growth. Chemicals used in water...
