UMass WET Center Publishes New PAA Research with Journal of the New England Water Environment Association

BioSafe Systems logo

East Hartford, CT— The Lake, Pond & Municipal division at BioSafe Systems has been working with the UMass Water and Energy Technology (WET) Center for the past year and a half to further the understanding of peroxyacetic acid (PAA) and its capabilities in wastewater treatment, especially the way it works in tandem with UV disinfection methods. Finally, we can share the research results.

The final stage of municipal wastewater treatment is “secondary effluent disinfection” and it follows cycles of physical, chemical, and biological processes. Our research determines how PAA performs at this stage as opposed to chlorine. The article details how varying PAA dosing rates, contact times, residuals, total coliforms (TC), and E. coli (EC) removal. BioSafe Systems’ OxyFusion® on-site generated PAA and BioSafe Systems’ Equilibrium PAA disinfectants proved effective for deactivating TC and EC in wastewater. Chlorine performs similarly but requires a higher dosing rate and longer contact time, but it also produces carcinogenic disinfection by-products that don’t occur with PAA.

UMass published the scientific paper in the Journal of New England Water Environment Association. It is the culmination of months of diligent, detailed work by Patrick Wittbold, Research Engineer, and Soon-Mi Kim, Ph.D. Candidate, and their team at UMass with support from BioSafe Systems’ Lead Chemical Engineer, Don Hobro, and our technical representatives for the Lake, Pond & Municipal division. The combined work of the UMass WET center and BioSafe Systems prove that progress is a team effort and the successful results of our research prove that PAA is not only effective in water disinfection and the on-site generation of non-acidic and odor-free PAA solutions are a game-changer.
