德克萨斯州州长提出了一项倡议，以评估 海水淡化以提供额外的供水。在这项倡议下，三 项目由德克萨斯州水资源开发委员会管理 （TWDB）。科珀斯克里斯蒂市为这三个项目中的一个获得了一笔拨款，即 “大型海水淡化示范项目可行性研究”。 该项目所需的产品水流量为25 mgd。然而，为了 生产25 mgd的成品水，需要考虑更大比例的原水 用于预处理和反渗透系统本身的废物流。 虽然调查涉及多个方面，但一个主要重点是确定 为该地区生产饮用水的潜在处理方法。因此 评估水源问题和处理方案，以及准备 设计标准、厂房和空间要求、估计资本和运营以及 对概念性海水淡化设施的维护成本进行了评估。 确定了几个可能的海水供应区域，包括几个工业区 现场、发电厂进水口和海岸沿线的其他区域。挑战已经实现 由于许多地区的高盐环境，这可能会增加饮用水的成本 水生产。因此，彻底审查水源选择以及 研究了地下水混合的可能性。源水和地下水的变化 混合会影响设计标准，如盐度、温度和预处理 要求。 拟建反渗透系统由两个通道组成。 在第二道中，盐水或 在第一阶段集中精力喂给第二阶段。第二阶段的浓缩物质量比原饲料质量好，因此被引导回饲料， 反渗透给水泵上游。这种两遍配置使用最少的 能源，同时预测水质始终低于既定标准 温度在10到30摄氏度之间时的最高水质限制。本文简要介绍了该项目的背景，介绍了项目目标，回顾 原水质量和成品水质量目标，以及反渗透 满足项目目标的海水淡化设计标准。包括3个参考文献、表格、图表。

The Governor of Texas created an initiative for the evaluation of the feasibility of seawater desalination to provide additional water supply. Under this initiative, three projects were created that were administered by the Texas Water Development Board (TWDB). The City of Corpus Christi secured a grant for one of the three projects, a "Large Scale Desalination Demonstration Project Feasibility Study". The required product water flow-rate of the project was 25-mgd. However, in order to produce 25-mgd of finished water, a larger portion of raw water is required to account for waste streams for the pretreatment and the reverse osmosis system, itself. While there were many facets to the investigation, a major focus was to identify potential treatment methods to produce potable water for the region. Therefore, an evaluation of source water issues and treatment alternatives, as well as preparation of design criteria, plant and space requirements, and estimated capital and operations and maintenance costs for a conceptual desalination facility was performed. Several areas were identified for potential seawater supply, including several industrial sites, a power plant intake, and other areas along the coast. Challenges were realized due to hypersaline conditions in many areas, which can increase the cost of potable water production. Therefore, a thorough review of source water options as well as the potential for groundwater blending was examined. The variation in source waters and blending impacted design criteria such as salinity, temperature, and pretreatment requirements. The proposed RO system consists of two passes. In the second pass, the brine or concentrate in the first stage feeds the second stage. The concentrate quality from the second stage is better than the raw feed quality, so it is directed back to the feed, upstream of the RO feed pump. This two-pass configuration uses the least amount of energy while projecting water quality that was consistently below the established maximum water quality limits at temperatures ranging from 10 to 30 degrees Celsius. This paper provides a brief background on the project, looks at project goals, reviews raw water quality and finished water quality goals, and looks at the reverse osmosis desalination design criteria to meet project objectives.
