AWWA WQTC65899

This powerpoint presentation begins by providing background information on recent model applications that include: water age modeling; supervisory control and data acquisition (SCADA) integrated modeling; daily operational improvements; tracking results; Total Trihalomethane (TTHM) Modeling; meet Stage 2 Disinfection Byproduct Rule; and, use distributed treatment technology. Chlorine demand equivalent model for single chlorination station is presented, along with a 1st order saturation growth model, all-pipes TTHM Results (1st Order Model, Feb. 2007), Distribution System TTHM Removal (AWWARF No. 03103), Pilot Treatment Plant Bulk Water Tests, and Air Stripping Plant Schematics. High priorities include: plan for a full-scale air-stripping demonstration plant at Far Hill Reservoir; development of chlorine dosing strategies for TTHM control; and, implementation for Stage 2 DBPR compliance. Includes figures.
