为了遵守《消毒剂/消毒副产品（D/DBP）规则》提出的新规定，许多公用事业公司将被要求修改其处理序列。许多公用事业公司将考虑使用臭氧作为预消毒剂/氧化剂来控制DBP。臭氧可以提供显著的C*t积分，减少氯需求，减少分配前所需的氯剂量。然而，臭氧氧化产生的副产品可能会引起健康问题。臭氧DBP包括有机DBP，如醛和酮酸，以及无机DBP溴酸盐。本研究的目的是系统地评估pH值对臭氧氧化俄亥俄河原水（通过玻璃纤维过滤器过滤）过程中溴酸盐形成的影响，在两种臭氧残留物的溴化物浓度范围内。

To comply with the new regulations proposed by the Disinfectants/Disinfection By-Products (D/DBP) Rule, many utilities will be required to modify their treatment trains. The use of ozone as a pre-disinfectant/oxidant will be an option considered for DBP control by many utilities. Ozone can provide significant C*t credit and decrease the chlorine demand, reducing the required chlorine dose prior to distribution. However, ozonation generates byproducts that may be of health concern. Ozone DBPs include organic DBPs, such as aldehydes and ketoacids and the inorganic DBP bromate. The objective of this research was to systematically evaluate the impact of pH on the formation of bromate during ozonation of raw Ohio River water (filtered through a glass fiber filter) for a range of bromide concentrations at two ozone residuals.
