本powerpoint演示文稿首先简要概述Startex Jackson Wellford Duncan（SJWD）水处理厂 位于 南卡罗来纳州斯帕坦堡县。2008年总体规划和基本建设改进 提出了项目建议，以及包括以下内容的试点测试目标:确定未来最合适的技术 设施 用以下两种方法评估斜板沉降器的有效性: 颗粒介质过滤器或膜过滤器； 比较颗粒介质过滤器与普通过滤器的性能。 膜过滤器；和 确定倾斜管道的设计和操作条件 平板沉降器、颗粒介质过滤器和膜 用于全面实施的过滤器。本文介绍了平板沉降器、颗粒介质和膜的中试结果，并对其进行了技术和经济评估 选择。结论和建议包括: 所有技术都能生产优质水 优化后的质量； 斜板沉降器运行良好，沉降水浊度较低（即较低的加载速率） 对于颗粒介质过滤器来说可能比 gpm/sf膜（gpm/sf/sf）与gpm/sf/sf膜（gpm/sf/sf/sf/sf/sf/sf/sf/sf/sf/sf/sf/sf/sf/sf； 颗粒介质过滤器 效果很好——颗粒和美观，是一个很好的选择 经过验证的流程；膜是 比颗粒介质更有效地去除颗粒；在美学上不如颗粒介质有效； 原水高锰酸盐的有效性不同； 应考虑后膜接触器（压滤机）； 膜污染（TCSF回收）；所需柠檬酸/盐酸； 在设计中考虑验证飞行员；和 成本略高，但评估表明成本更高 利益包括表格、数字。

This powerpoint presentation begins by providing a brief overview of the Startex Jackson Wellford Duncan (SJWD) Water District located in Spartanburg County, South Carolina. A 2008 master plan and capital improvements program recommendation is presented, along with pilot testing objectives that include the following: determine most appropriate technology for future facilities; evaluate inclined plate settler effectiveness with either granular media filters or membrane filters; compare performance of granular media filters vs. membrane filters; and, establish design and operating conditions for inclined plate settlers, granular media filters, and membrane filters for full-scale implementation. Pilot testing results are presented for plate settlers, granular media, and membranes, along with a technical and economic evaluation of alternatives. Conclusions and recommendations included the following: all technologies were capable of producing good water quality if optimized; inclined plate settler worked well, and the lower settled water turbidities (i.e. lower loading rates) were likely more important for granular media filters than membranes (0.3 gpm/sf versus 0.25 gpm/sf); granular media filter worked well - particulates and aesthetics, and was a proven process; membranes were more effective than granular media for particle removal; less effective than granular media for aesthetics; effectiveness of raw water permanganate varied; post-membrane contactor (pressure filter) should be considered; membrane fouling (TCSF recovery); citric acid/hydrochloric acid required; consider proof pilot during design; and, slightly greater cost, but evaluation indicates greater benefit.
