Fate and Effect of Peracetic Acid Solutions on Biological Wastewater Treatment Systems
Peracetic acid (PAA), as a wide-spectrum effective disinfectant, has been extensively and increasingly used in many industries, especially in poultry processing to control food-borne pathogens. Upsets of biological wastewater treatment processes and failures of whole effluent toxicity (WET) tests …

Inactivation mechanisms of human norovirus surrogate Tulane virus by peracetic acid at different pHs
… and mechanisms of a potential disinfectant named peracetic acid (PAA) on Tulane virus (TV), a surrogate for human norovirus, at pH 7.8, 5.4 and 4.5. No significant difference was observed between the inactivation kinetics under different concentrations and pHs. A 2.5-log10 reduction in TV …

Simulation studies to profile development and control of mixed-culture static and dynamic biofilms during extended raw beef processing operations using combinations of nanobubble water and peracetic acid
… properties—in combination with peroxyacetic acid (PAA)—a strong oxidizer commonly used in meat processing—to control mixed-species biofilm development on stainless steel (S304) and rubber (Buna-N) surfaces over extended processing times. Experiments were conducted under simulated beef …

Sanitizer efficacy towards attached bacteria in a simulated milk pipeline system using pure and mixed cultures
… [chloline (200 ppm), iodophor (2S: ppm), acid anionic (200 ppm), peracetic acid (200 ppm), and fatty acid sanitizer (200 ppm)], was evaluated against bacteria attached to gasket materials. Pseudomonas fluorescens, Yersinia enterocolitica, Bacillus cereus, and Listeria monocvtogenes were …

Sanitizer efficacy against bacteria attached to synthetic meat processing surfaces
… quaternary ammonium compound and phosphoric acid (200 ppm), and peracetic acid (185 ppm). In subsequent studies, the same sanitizers were tested against bacteria attached to polyvinyl chloride, polyurethane, and high density polyethylene surfaces. Test surfaces in sterile poultry slurries …

Differential Response of Various Spore Species to Sporicidal Disinfectants
… not evaluated this effect on spores exposed to peracetic acid-based disinfectants. Recently, our lab has evaluated two novel peracetic acid-based chemical disinfectants, PeraDox™ and PeraDox Ultra™ for their activity against a variety of bacterial agents. Results indicated that the PeraDox™ …

Observation and Nature of Non-statistical Dynamic Effects in Ordinary Organic Reactions
… theories. This is in contrast with Lewis-acid catalyzed and thermal DA reactions, which exhibit substantial "normal" intramolecular KIEs that are in accord with TST predictions. Finally, the Baeyer-Villiger oxidation of cylohexanone in water was investigated. KIEs were measured for the …

The Presence of Pathogenic Bacteria in Recirculating Aquaculture System Biofilms and their Response to Various Sanitizers
… hypochlorite, quaternary ammonium compound, or peracetic acid. Ozone was bubbled directly into one tank to treat another set of disks. The modified E. coli were isolated and counted. Total aerobic plate counts and Enterobacteriaceae counts were performed. Statistical analysis indicated that the …

The synthesis and reactions of sulphur analogues of deoxyvasicinone
… was achieved, by the condensation of anthranilic acid with appropriate sulphur containing lactams, in the presence of phosphoryl chloride. The quinazolinones (A) and (B) were shown to react (at the methylene group alpha to the carbon-nitrogen double bond) with a variety of electrophiles at …

Drinking water disinfection by-products detection, formation and the precursors removal study
"Haloacetic acids (HAAs) and trihalomethanes (THMs) are two groups of commonly found disinfection by-products (DBPs). Iodinated THMs and HAAs were observed after disinfection of water containing high level of iodide and are proved to be more toxic than their corresponding chlorinated and brominated …

Occurrence, monitoring and removal of drinking water contaminants by advanced technologies
… formation by an alternative disinfectant (peracetic acid, PAA). Perchlorate monitoring was performed at higher risk DWTP locations within the state of Missouri with levels below the estimated regulatory limit (4 µg/L or higher). Perchlorate removal from drinking water was also studied by …

Harmful algae, algal toxin, taste and odor control and mitigation in public water system
… chlorine, chlorine dioxide, permanganate, and peracetic acid (PAA) were compared for controlling <em>M. aeruginosa</em>, <em>C. raciborskii</em>, and related cyanotoxins, i.e., MC-LR and CYN. At the same time, the disinfection byproduct (DBPs) formation during oxidations of cyanobacteria and …
