Peracetic Acid Disinfection: Implementation Considerations for Water Resource Recovery Facilities

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.
