This powerpoint presentation begins by presenting background information on the bromate mitigation project, including: plant operation prior to study; bromate formation; and, an initial study done in 2006-2007. Bromate mitigation objective included: demonstrate Bromate Mitigation Strategies at full-scale level; pH depression via CO₂ addition; and, Cl₂/NH₃ addition. The Bromate Mitigation Testing Layout is presented, along with demonstration testing, preliminary CO₂ data analysis CO₂ testing results (pH = 7.2) and (O3/TOC = 1.0), CO₂ dosing, observations of CO₂ testing, Cl₂/NH₃ additional testing, status and results (bench-scale), and TTHM formation (Bench-Scale). Includes figures.
