The Impact of Peracetic Acid on Receiving Waters: Biochemical Oxygen Demand and Dissolved Oxygen

The use of peracetic acid (PAA) for wastewater disinfection has seen significant growth in North America over the last several years due to its advantages over chlorine-based chemistries. This month’s edition of the Disinfection Forum examines the role PAA plays in the formation of both biochemical oxygen demand and dissolved oxygen, two competing mechanisms that impact the health of the plant’s receiving stream.
