Description
In order to comply with the regulations for disinfection byproducts, many utilities areutilizing alternative disinfectants, such as chlorine dioxide (ClO<sub>2</sub>) and chloramines, and areminimizing free chlorine (Cl<sub>2</sub>) contact time. This study investigated the ability or inability ofClO<sub>2</sub>, Cl<sub>2</sub>, and potassium permanganate to oxidize fishy/swampy/grassy odorants, and powderedactivated carbon (PAC) to adsorb these compounds. ClO<sub>2</sub> was found to be a selective oxidantfor the control of these types of taste-and-odor problems, whereas maintaining some free Cl<sub>2</sub>contact time (e.g., through the filters) or use of permanganate or PAC may be needed if prechlorinationis eliminated. Includes 12 references, table, figures.
