Mechanisms of Peracetic Acid Inactivation of Microbes

Peracetic acid (PAA) is a highly effective biocide that has gained in popularity over the past several years as a chlorine alternative for wastewater disinfection. While the benefits of PAA as a wastewater disinfectant have become apparent, only limited work identifying the mechanisms by which PAA inactivates bacteria and viruses has been performed to date.

This edition of the Disinfection Forum discusses the state of the literature with respect to PAA inactivation of microbes.
