科罗拉多州红山森林（Redhill Forest，科罗拉多州）处理厂是一个小型、全尺寸的离子交换系统，用于去除井水中的铁、硬度和镭。该工厂还包括一个曝气过程，用于去除溶解的氡气和二氧化碳气体。该工厂的一个独特特点是，从离子交换系统中去除废盐水中的镭，并在镭选择性络合剂（RSC）上永久络合。RSC树脂在需要时被更换，并被送往接受低放射性废物的场所进行最终处置。包括21个参考文献、表格和图表。

A small, full-scale ion exchange system, the Redhill Forest (Colo.) treatment facility, removes iron, hardness, and radium from well water. The plant also includes an aeration process for removing dissolved radon and carbon dioxide gases. A unique feature of the plant is a process that removes radium in the waste brine from the ion exchange system and complexes it permanently on a radium-selective complexer (RSC). The RSC resin is replaced when needed and is sent for final disposal to a site that accepts low-level radioactive wastes. Includes 21 references, tables, figure.
