本powerpoint演示文稿首先简要概述了Cache Creek赌场和目的地 加利福尼亚州拉姆西度假村，作为使用重用应用程序的示例。供水挑战包括高背景总溶解固体（TDS）浓度 通过闭环重用和 低废水排放TDS限制。介绍了用水、水源和水处理的特点，以及策略1废水处理- 去除废水中的TDS，以及策略2地下水处理- 从地下水井中清除TDS。候选流程包括: 反渗透；石灰软化；以及电渗析逆转（EDR）。概述了盐水截留浓度、选择和实施。包括桌子。

This powerpoint presentation begins by providing a brief overview of the Cache Creek Casino and Destination Resort, Rumsey, California that serves as an example of using a reuse application. Water supply challenges included high background total dissolved solids (TDS) levels concentrated by closed-loop reuse and low wastewater effluent TDS limits. Characteristics of water usage, water sources, and water disposal are presented, along with Strategy 1 Wastewater Treatment - remove TDS from wastewater effluent, and Strategy 2 Groundwater Treatment - remove TDS from groundwater wells. Process candidates included: reverse osmosis (RO); lime softening; and, electrodialysis reversal (EDR). Brine rejection concentration and selection and implementation are outlined. Includes tables.
