A field study on the effectiveness of perforated baffles in an existing cross-baffled serpentine flow chlorine contact chamber is reported. The object of the method studied was to increase the hydraulic efficiency and lower the required chlorine dose. A cross-baffled serpentine flow chamber was chosen because it is a common design. Tracer curves and disinfection efficiency were monitored on a modified and unmodified chlorine contact chamber simultaneously operating under equal conditions. Data generated from these field tests and batch reactor experiments were used to determine the efficiency increase achieved from these baffles, and to project the expected benefit of these modifications as an interim solution at municipal treatment plants.
