本powerpoint演示文稿首先简要概述了科罗拉多河水的补给和混合 天然地下水。介绍了水质和处理目标，以及实现目标所需的流程。测试目标包括: 评估IX是否能降低钡水平；最大限度地减少海水生产 再生 评估RO和NF相对盐 拒绝和操作压力；和 评估VSEP膜的选择。有待解决的离子交换问题 介绍了离子交换测试参数，并对离子交换测试进行了总结 结果包括: SAC（Na+）是唯一可靠的 达到0.02 mg/L钡的目标； 钡在室温下突破（0.02 mg/L）~ 500张床位； Amberlite PWC14表现最好 在四种SAC（Na+）树脂中；而且，盐的需求量超过了 之前假设的（9.57磅对3.92磅 每处理1000加仑的盐含量）。包括表格、数字。

This powerpoint presentation begins by providing a brief overview of recharging Colorado River water and blending it with native groundwater. Water quality and treatment goals are presented, along with processes needed to meet goals. Testing objectives included the following: evaluate if IX can reduce barium levels; minimize brine production from regeneration; evaluate RO and NF relative salt rejection and operating pressures; and, evaluate VSEP membrane selection. Ion exchange issues to be researched are presented, along with ion exchange testing parameters, and a summary of IX testing results that include the following: SAC (Na+) was the only resin to reliably meet barium goal of 0.02 mg/L; Barium broke through (0.02 mg/L) at ~ 500 bed volumes; Amberlite PWC14 performed the best out of the four SAC (Na+) resins; and, salt requirements were more than previously assumed (9.57 lb vs. 3.92 lb of salt per 1,000 gallons treated). Includes tables, figures.
