Abstract
Wastewater treatment plants (WWTPs) that employ chlorine or chlorine dioxide for disinfection maintain a small total
residual chlorine (TRC) in the plant effluent prior to discharging
into receiving bodies of water. A TRC as low as 0.02 milligram per liter (mg/L) is toxic to aquatic life. The NPDES permits for
WWTPs in Georgia are now being issued with a very low TRC limit, making it necessary to add a dechlorination step in such
plants. The paper outlines an evaluation and comparison of available dechlorinating chemicals, demonstrates the cost analysis
procedure and describes the influence of non-cost related aspects in the final selection of a chemical.
