本powerpoint演示文稿首先简要概述了加利福尼亚州图卢姆的水处理设施。介绍了水质和预设计分析，以及传统软化工艺和颗粒软化。介绍了颗粒软化试验研究，包括以下目标: 将硬度范围降至60-75 mg/L； 降低铁和锰的浓度，使其降低 低于SMCL、0.3 mg/L和0.05 mg/L， 分别地 评估整个系统的性能；并确定全面运行的操作考虑因素 过程提供了初步研究结果、Tuolomne工厂设计，以及美国境内正在运行的软化设施清单，包括表1。

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.
