Full Description

In order to comply with the regulations for disinfection byproducts, many utilities areutilizing alternative disinfectants, such as chlorine dioxide (ClOsub2/sub) and chloramines, and areminimizing free chlorine (Clsub2/sub) contact time. This study investigated the ability or inability ofClOsub2/sub, Clsub2/sub, and potassium permanganate to oxidize fishy/swampy/grassy odorants, and powderedactivated carbon (PAC) to adsorb these compounds. ClOsub2/sub was found to be a selective oxidantfor the control of these types of taste-and-odor problems, whereas maintaining some free Clsub2/subcontact time (e.g., through the filters) or use of permanganate or PAC may be needed if prechlorinationis eliminated. Includes 12 references, table, figures.
