在两家水务公司进行了一项中试工厂研究，以评估用于三卤甲烷（THM）控制的替代消毒剂——臭氧、过氧化氢、二氧化氯、氯胺和高锰酸钾，并确定其使用对小型水系统的影响。空气剥离和活性炭也进行了评估。替代消毒剂的组合将三卤甲烷的浓度降低到一个范围，从使用氯的约160微克/升到80微克/升（氯一氯胺）或<5微克/升（臭氧一氯胺）。估算了将各种工艺改造纳入小型水系统的成本。包括17个参考文献、表格、图表。

A pilot-plant study was conducted at two water utilities to evaluate alternative disinfectants--ozone, hydrogen peroxide, chlorine dioxide, chloramines, and potassium permanganate--for trihalomethane (THM) control and to determine the impact of their use on small water systems. Air stripping and activated carbon were also evaluated. Combinations of alternative disinfectants reduced THMs to a range of levels from approximately 160 ug/L using chlorine to 80ug/L (chlorine-monochloramine) or <5 ug/L (ozone-monochloramine). The costs of incorporating various process modifications into small water systems are estimated. Includes 17 references, tables, figures.
