科罗拉多州东樱桃溪河谷水与卫生区（ECCV）正在规划一个最初的10 mgd海水淡化设施，在建设40 mgd海水淡化设施时，该设施将是最大的内陆海水淡化设施之一 在美国。本研究评估了使用低压反渗透（RO）膜作为一种经济高效的方法来处理内陆咸水，以补充ECCV的当前和未来 要求。试点研究的目标是: 确定适用于全尺寸系统的RO系统运行参数； 验证预选反渗透膜的性能； 评估Beebe抽油井水的结垢和结垢可能性； 评估工艺预处理要求； 为ECCV员工提供RO系统培训；和 确定RO渗透水与原水的可接受混合物，以 实现配水系统的味道和气味目标。调查的关键标准包括预处理要求（阻垢剂 选择和酸进料要求），通过传质测量操作压力和生产率 系数（MTC、gfd/psi）、拒收性能、混合水质量和浓缩水质量。 在整个研究过程中，膜的产品水回收率高达85%。ECCV RO 这项先导性研究使用Beebe从科罗拉多州Lochbuie的一口现有水井中抽取地下水。这个网站是 之所以选择反渗透中试研究，是因为该井提供了可靠的供水，水质典型 Beebe Draw含水层的。ECCV正在评估靠近油井的潜在井场 具有相似的水质特征。 包括4个参考文献、表格和图表。

East Cherry Creek Valley Water & Sanitation District (ECCV), Colorado, is planning an initial 10-mgd desalination facility that at build-out of 40-mgd would be one of the largest inland desalination facilities in the United States. This study evaluated the use of low-pressure reverse osmosis (RO) membranes as a cost-effective means to treat inland brackish groundwater to supplement ECCV's current and future demands. Pilot study objectives were to: determine RO system operating parameters applicable to full-scale systems; verify performance for pre-selected RO membranes; evaluate fouling and scaling potential of Beebe Draw well water; evaluate process pretreatment requirements; provide RO system orientation for ECCV staff; and, determine acceptable blend of RO permeate water with raw well water to achieve taste and odor goals for distribution system water. Key criteria investigated include pretreatment requirements (antiscalant selection and acid feed requirements), operating pressures and productivity measured by mass transfer coefficient (MTC, gfd/psi), rejection performance, blend water quality, and concentrate water quality. Membranes were operated at a high product water recovery of 85% throughout the study. The ECCV RO pilot study used Beebe Draw groundwater from an existing well in Lochbuie, Colorado. This site was chosen for the RO pilot study because the well provides a reliable water supply with water quality typical of the Beebe Draw aquifer. ECCV is evaluating potential well sites that will be in proximity to the well with similar water quality characteristics. Includes 4 references, tables, figures.
