Controlling Bromate Formation: During Ozonation With Chlorine and Ammonia
The Stage 1 Disinfectants/Disinfection Byproducts Rule (D/DBPR) includes a 10 μg/L limit for bromate. For many utilities that have included ozonation in their treatment processes, compliance with the bromate standard can pose a considerable challenge if raw water supplies contain bromide at concentrations approaching 100 μg/L or higher. This challenge is accentuated if the ozonation process is designed for or modified to provide inactivation of Cryptosporidium parvum. This article describes how the Southern Nevada Water Authority (SNWA) recognized this challenge and initiated a research program to develop an optimal treatment method to minimize bromate formation when operating its ozonation facilities to achieve an internally adopted target of 2‐log (99%) Cryptosporidium inactivation. This research culminated in the issuance of a patent that has been placed in the public domain.
