这项研究调查了来自软化的水源水 佛罗里达州、密苏里州、内布拉斯加州和南部的植物 达科他州和德克萨斯州将评估水源水质 不同的石灰剂量会影响软化和去除 天然有机物（NOM）和消毒副产品 （DBP）形成。大多数石灰软化厂 很可能能够满足移除 有机碳及其对DBP形成的限制 在石灰添加量略低于 导致镁浓度显著降低。 这种操作条件是最佳的，因为 限制可能产生的污泥量 增强软化。 对于使用沉淀软化的公用事业公司的经理， 这些发现为深入了解 电厂运行对移除NOM和 控制DBP。此外，剂量标准化 为这项研究开发的软件将使公用事业公司能够轻松 将它们的操作与其他工厂的操作进行比较 具有不同的水特征。包括29个参考文献、表格和图表。

This research investigated source waters from softening plants in Florida, Missouri, Nebraska, South Dakota, and Texas to evaluate how source water quality and varying lime doses affected softening, removal of natural organic matter (NOM), and disinfection byproduct (DBP) formation. Most lime softening plants are likely to be able to meet regulations for removal of organic carbon and limitations on DBP formation by operating with lime addition just below the level that causes dramatic reduction of the magnesium concentration. This operating condition is optimal because it limits the amount of sludge that could be created by enhanced softening. For managers of utilities that use precipitative softening, the findings provide insight into the effects of plant operation on the ability to remove NOM and control DBPs. In addition, the dose normalization developed for this research will allow utilities to easily compare their operations with those of other plants having different water characteristics.
