Posttreatment Aeration to Reduce THMs

AWWA Journal, October 2011

Posttreatment aeration inside water storage tanks can be used as a cost-effective option to strip trihalomethanes from finished water. This paper explores how different design variables affect THM removal rates for diffused aeration and spray aeration systems.
