Title:Webcast: Reducing Volatile DBPs in Treated Drinking Water Using Aeration Technologies
​With the Stage 2 Disinfectants/Disinfection Byproducts Rule now implemented, many water utilities across the United States have or are considering aeration as a means to achieve compliance with the total trihalomethanes (TTHMs) MCL. For systems with only TTHM concerns and no compliance issues with the five haloacetic acid (HAA5) concentrations, aeration can be an attractive solution. It has lower capital and operating costs compared to most precursor removal processes or alternative disinfectants, which present their own operational costs and challenges. TTHM aeration can be used at clearwell and/or remote locations in the distribution system to treat only the fraction of water requiring TTHM reduction for LRAA compliance, further reducing costs.​

WRF has recently completed two projects to provide guidance on the design, permitting, operation, and maintenance of aeration systems for reduction of TTHMs:

​​This Webcast provided a comprehensive overview of the projects’ objectives, results, and recommendations and will be very instructive to water utilities across the country that have high TTHMs in their treated water or in distribution systems.​
