本powerpoint演示文稿首先简要概述了西邓迪水处理村，特别是Angle Tarn工厂——一家使用 离子交换，1.67 MGD， 软化和去钡， 阳离子、NaCl再生和Randall Oaks植物——一种使用 设计/蓄水层相同。治疗问题包括: Angle Tarn工厂-无残留问题， 再生剂废物排放至盐水池并计量至污水管；Randall Oaks工厂——残留问题， 废物排放至东邓迪污水处理厂。介绍了试验装置，包括 给出了设备和布局以及结果 操作参数； 钡； 出水水质； 污泥特性；和 镭包括表格、数字。

This powerpoint presentation begins by providing a brief overview of the Village of West Dundee Water Treatment, specifically the Angle Tarn Plant - an existing plant that uses ion exchange, 1.67 MGD, softening and barium removal, and cationic, NaCl regeneration, and the Randall Oaks Plant - a new plant using the same design/aquifer. Treatment issues included: Angle Tarn Plant - No Residuals Problem, regenerant waste discharged to brine pit and metered to sanitary sewer; Randall Oaks Plant - residuals problem, waste discharged to East Dundee WWTP. The pilot set-up is presented, including equipment and layout, and results are given for operating parameters; barium; effluent quality; sludge characterization; and, radium. Includes tables, figures.
