This powerpoint presentation begins by providing a brief overview of the Tuolumne, California, water treatment facility. Water quality and pre-design analysis are presented, along with traditional softening processes, and pellet softening. A pellet softening pilot study is presented, including the following objectives: reduce the hardness range to 60 - 75 mg/L; reduce iron and manganese concentrations to fall below SMCL, 0.3 mg/L and 0.05 mg/L, respectively; assess overall system performance; and, determine operational considerations for full scale process. Pilot study results are provided, along with the Tuolumne Plant design, and a listing of softening facilities in operation within the U.S. Includes table.
