分析了七家使用臭氧作为预氧化剂的公用事业公司的水，以确定臭氧对去除总有机碳（TOC）和三卤甲烷（THM）前体的影响，以及对水中悬浮颗粒碰撞效率因子和电泳迁移率的影响。确定了有利于使用臭氧作为助凝剂的水质特征。结果表明，在实践中常用的剂量下，预臭氧层可将THM的生成潜力降低约10%，并可获得最佳臭氧层- 发现在硬度与TOC之比大于25 mg CaCO3/mg C且臭氧剂量约为0.4-0.8 mg O3/mg C的水中会发生诱导颗粒失稳。包括59篇参考文献、表格和图表。

Waters from seven utilities that use ozone as a preoxidant were analyzed to determine the impact of ozone on the removal of total organic carbon (TOC) and trihalomethane (THM) precursors and on the collision efficiency factor and electrophoretic mobility of suspended particles in the water. Water quality characteristics that favor the use of ozone as a coagulant aid were identified. Preozonation was shown to lower THM formation potential by about 10 percent at the dosages commonly used in practice, and optimal ozone-induced particle destabilization was found to occur in waters with hardness-to-TOC ratios > 25 mg CaCO3/mg C and ozone doses of about 0.4 - 0.8 mg O3/mg C.
