Jonathan Rogers Water Treatment

‹

The Jonathan Rogers Water Treatment Plant expansion included two duplicate 10 MGD trains, which were added to the existing four treatment trains. Other expanded and/or modified treatment processes included pond pre-sedimentation, pre-treatment ozonation, coagulant and polymer aided sedimentation, pre-filter ozonation, granular activated carbon filtration, and clear well disinfection. Ancillary systems were expanded to add 20 MGD, more flow, a screw pump at the influent pump station, ozone distribution piping and an off-gas destruct system, polymer and coagulant aid facilities, a sludge pump station, pre-filtration pump station, and a water pumping distribution system. The instrumentation and controls system was updated to integrate the new treatment trains with the existing system for increased operator control, treatment optimization, and system troubleshooting.
