Abstract

This research investigated the effect of different ozone dissolution systems on disinfection credit and bromate formation. A case study at the Region of Halton provides full-scale evidence regarding the difference between ozone dissolution using fine bubble diffusion (FBD) versus side stream injection (SSI) with degas. Pilot-scale research investigated several research gaps to assist utilities, design engineers, and manufacturers to better understand the impact of different types of ozone dissolution systems on disinfection credit and bromate formation. The application of these results provides utilities with cost information needed to make decisions regarding which method of ozone mass transfer is appropriate.
