在内华达州法伦海军航空站（NAS）对两种去除饮用水中砷的处理方法——活性氧化铝和离子交换——的中试工厂试验进行了评估。砷浓度为0.080-0.116 mg/L，超过了0.05-mg/L的最大污染物水平。虽然砷的价态尚未确定，但预氯化过程和测试结果表明，它可能是砷V。NAS的氯化饮用水用于评估几种不同条件下的处理效果。活性氧化铝和离子交换系统分别通过三个不同的加载和再生循环运行。影响这些方法去除砷的主要水质因素是:给水pH值、砷浓度、硫酸盐浓度和碱度。影响去除的主要操作因素有:流速、停机时间和介质堵塞。在最佳pH（5）下，对活性氧化铝法去除砷的资本和运营成本进行了估算。 5） 对于从同一含水层取水的三个小型社区系统。此外，还对垃圾填埋场中使用的几种无毒垃圾处理容器进行了表征。包括6个参考文献、表格、图表。

Pilot-plant tests of two treatment methods - activated alumina and ion exchange - for removing arsenic from drinking water were evaluated at the Fallon, Nevada, Naval Air Station (NAS). The arsenic concentration was 0.080-0.116 mg/L, exceeding the 0.05-mg/L maximum contaminant level. Although the valence of arsenic was not determined, the prechlorination process and test results suggest it was probably arsenic V. Chlorinated drinking water from the NAS was used for evaluating the efficacy of treatment under several different conditions. The activated alumina and ion exchange systems were operated through three different loading and regeneration cycles each. The major water quality factors affecting the removal of arsenic by these methods were: pH of feedwater, arsenic concentration, sulfate concentration, and alkalinity. The major operational factors affecting removal were: flow rate, down time, and media clogging. Capital and operating costs for arsenic removal are estimated for the activated alumina method at optimum pH (5.5) for each of the three small community systems drawing water from the same aquifer. In addition, several containers of the regeneration waste were used for a special study to characterize, dewater, and render the waste nontoxic for disposal in a sanitary landfill.
