Researchers explore the effect of PPA in processing wastewater treatment systems

A new research project, funded by industry groups like the USPOULTRY Foundation, has investigated the effect of PPA solutions in poultry processing wastewater treatment systems.

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 investigated the effect of peracetic acid (PAA) solutions in poultry processing wastewater treatment systems.

The research was made possible in part by an endowing Foundation gift from the Stanley & Dorothy Frank Family Foundation and is part of the Association’s comprehensive research program encompassing all phases of poultry and egg production and processing.

A brief summary of the completed project is shown below. A complete report, along with information on other Association research, may be obtained through USPOULTRY’s website. The project summary is as follows.

Project #715: Fate and Effect of Commercial Peracetic Acid Solutions in Poultry Processing Wastewater Biological Treatment Systems

(Dr Spyros G Pavlostathis and Dr Jinchen Chen, School of Civil and Environmental Engineering, Georgia Institute of Technology, Atlanta, Georgia)

Dr Spyros G Pavlostathis and Dr Jinchen Chen at the Georgia Institute of Technology recently completed a research project that quantified H2O2 decomposition kinetics in dissolved air flotation (DAF) effluent, as well as the long-term effect of peracetic acid (PAA) and H2O2 on the treatment efficiency of biological aerobic, nitrifying and denitrifying degradation processes.

The outcome of this study provides systematic information to the poultry processing industry to develop a sound methodology and employ other measures that will ensure the continuous use of PAA solutions to achieve pathogen-free products, while avoiding upsets of biological processes used for the treatment of PAA-bearing wastewater.

The research summary can be found on the USPOULTRY website.
