Peracetic acid (PAA) has gained popularity as a wastewater disinfectant in recent years due to its inherent advantages over established disinfectants particularly in challenging conditions. Used for decades as a disinfectant in the food and beverage industry, application of PAA at water resource recovery facilities (WRRFs) is a burgeoning topic with a growing number of full-scale systems located throughout the United States including numerous installations in Kentucky and Tennessee. This presentation will include an overview of PAA disinfection kinetics, advantages and challenges of PAA when compared to established wastewater disinfectants, suitable PAA disinfection applications, and design and operational considerations for implementing a PAA disinfection system.
