Total Organic Carbon (Total Organic Carbon (TOC) RemovalTOC)

Natural Organic Matter (NOM), as generally quantified by Total Organic Carbon (TOC), reacts with chlorine to form disinfection by-products (DBP’s) such as trihalomethanes (THM’s) and haloacetic acids (HAA’s). Through the use of enhanced coagulation with iron-based coagulants TOC’s can be greatly reduced preventing the formation of DBP’s. Ferric Sulfate can effectively remove TOC’s over a wide range of raw water conditions, but with higher raw water pH.
