Peracetic Acid Disinfection

Many utilities in the United States and Canada are looking to peracetic acid (PAA) disinfection, a technology that has been used in Europe for more than a decade, as a part of a risk management decision to reduce or eliminate gas chlorine and other disinfection byproducts from their treatment processes. However, there is a paucity of information available about the evaluation and implementation of this technology. This special publication aims to provide an overview of the chemistry and kinetics of PAA disinfection, along with information for design, permitting, and implementation of the technology.
