USPOULTRY and the USPOULTRY Foundation announce the completion of a funded research project at the Georgia Institute of Technology in Atlanta, Georgia, in which researchers evaluate the fate and effect of peracetic acid in poultry processing wastewater treatment systems. The research was made possible in part by an endowing Foundation gift from Sanderson Farms and is part of the Association’s comprehensive research program encompassing all phases of poultry and egg production and processing. A summary of the completed project is as follows.
Peracetic Acid (PAA) remaining after its reaction with wastewater constituents may impact biological wastewater treatment processes. Thus, Dr. Spyros G. Pavlostathis and associates at the Georgia Institute of Technology recently completed a research project that aimed to evaluate the fate and effect of PAA in poultry processing wastewater treatment systems. Overall, the results suggest that aerobic and anoxic organic matter degradation, as well as nitrification, denitrification and anaerobic degradation with poultry processing wastewater, will not be affected during the normal plant operation when residual PAA and Hydrogen Peroxide (H2O2) are not present in the wastewater. However, nitrification, denitrification and anaerobic degradation will be affected when wastewater with high residual PAA concentrations are expected at the end of the plant operation shift due to emptying of chiller tanks, or in the case of accidental PAA solution spills.
The research summary can be found on the USPOULTRY website. Members interested in reviewing the full report can contact USPOULTRY Vice President of Research Dr. Denise Heard at [email protected].
