“…The concentrations used in our study (30-220 mg L −1 ) for PAA and (30-120 mg L −1 ) for PFA were so high that the results cannot be well compared to earlier disinfection works, where peracid concentration was up to 10 mg L −1 in treated wastewater [26] or aquarium water [27]. Our inoculum of 0.1 mL could have contained up to 3.3 mg organic matter, which was added to 5 mL of exposure solution, meaning that the solution's organic matter concentration was 660 mg L −1 if the organic matter, which was consumed by clostridial growth before exposure tests, was ignored.…”

“…The resistance of bacteria against peracids is known to be affected by temperature, peracid concentrations and organic matter (as casein or peptone), as these factors increase the degradation of peracids and thereby the formation of degradation products, such as peroxyls or hydroxyl radicals [26]. It has been found that the decay rate of PAA increases when the temperature increases from 20 to 30 • C and the concentration of organic matter in medium increases from 0 to 70 mg COD L −1 [27].…”

We did not measure the decay of PFA or PAA during the exposure of 5 or 10 min, but there must have been some decay due to the high level of organic matter [26,27].…”

Clostridia are anaerobic spore-forming bacteria, which degrade carbohydrates to butyric acid, carbon dioxide, hydrogen and other compounds. These bacteria are commonly found in feces of ruminants, from where they can enter to udders and milk via manure or fodder. This study was done to find a sustainable sanitation method to control the resistant clostridial spores as they are difficult to control in the food processing industry. Clostridia spoil cheeses and other dairy products, and thereby increase the carbon footprint of products and cause economical losses in the dairy industry. The efficacy of two organic peroxides; peracetic acid (PAA) and performic acid (PFA) was tested against 30 clostridia strains isolated from cattle slurry, silage, or spoiled cheeses. PAA, at a concentration of 220 mg L −1 , only eliminated 6/30 clostridia strains, whereas PFA totally eliminated 26/30 clostridia strains at a concentration of 120 mg L −1 . PFA therefore seems to be a more potent disinfectant than the more commonly used PAA. PFA is an effective disinfectant against Clostridium tyrobutyricum and other resistant clostridia at 120 mg L −1 for 5-10 min contact time at room temperature.

“…In water, PAA may decompose by various water matrix components. For example, transition metals, such as Fe and Co, can catalytically decompose PAA. ,,, Domínguez-Henao et al reported that inorganic nitrogen compounds (ammonia nitrogen, nitrate, and nitrite) did not have any significant effect on PAA decay at the typical concentration level of nitrogen in secondary wastewater effluents. In contrast, phosphate ions, casein, and peptone had significant impacts on PAA decomposition .…”

“…Peracetic acid [or peroxyacetic acid, CH 3 C(O)OOH, PAA] is an oxidant that is attracting greater interest in research and applications. − The applications of PAA have occurred in various industries, including food processing, medical, chemical, and pulp and paper industries, for its high oxidation capability and antimicrobial activity. − PAA has also increasingly been used in wastewater disinfection owing to its high disinfection efficiency and lower level of formation of harmful disinfection byproducts (DBPs) compared to the conventionally used chlorine oxidants. ,− Some recent review papers have updated the weak ecotoxicological effects of PAA-treated wastewater effluents, as well as the lower level of generation of persistent toxic or mutagenic residuals or byproducts from PAA-based pulp bleaching. , According to a recent report, the global PAA market was worth $650 million in 2017 and will grow to $1.3 billion by 2026, and the PAA market for wastewater treatment specifically is expected to grow by 8% per year over that same time frame…”

Reactivity of Peracetic Acid with Organic Compounds: A Critical Review

2020

View full text Add to dashboard Cite

As an emerging oxidant and disinfectant, peracetic acid (PAA) has increasingly been used in wastewater treatment and the food and medical industries and has attracted greater research interest. To better understand reactions initiated by PAA, this paper is among the first to comprehensively review the reactivity of PAA with respect to organic compounds of various structures. The reactivities of PAA with respect to 123 organic compounds are compiled from the literature and new experiments, and possible reaction pathways and products are discussed. Overall, PAA is an electrophile with high selectivity in reaction. The second-order rate constants of PAA oxidation of organic compounds vary by nearly 10 orders of magnitude, from 3.2 × 10 −6 to >1.0 × 10 5 M −1 s −1 , which are much larger than those of H 2 O 2 coexisting in PAA solutions. Electron-donating groups of compounds increase the reactivity with respect to PAA, evidenced by the strong negative correlations between rate constants and substituent constants [Hammett (σ) or Taft (σ*)] of compounds. Sulfur moieties show exceptionally high reactivity with respect to PAA. Limited studies have shown that generally oxygen-added reaction products are formed from PAA oxidation. This critical review provides a useful foundation for advancing our understanding of the fate of organic compounds in wastewater treatment including PAA and identifies further research needs to evaluate a broader range of compounds and their oxidation products and toxicity.

BACKGROUND: This study investigates a novel, efficient and green pretreatment approach using ferrous iron catalyzed peracetic acid oxidation (Fe 2+ /PAA) on anaerobic fermentation of waste activated sludge. The underlying mechanisms are also studied for both the chemical and microbial effects. RESULTS:The results indicate that Fe 2+ /PAA exhibit significant positive synergistic effect on short-chain fatty acid (SCFA) generation, especially acetic acid. The maximal SCFA concentration of 272 mg COD g −1 VSS is obtained with Fe 2+ (2.7 mmol L -1 )/PAA (3.0 mmol L -1 ), which is 5.2 times that of the control test. Fe 2+ /PAA can effectively facilitate sludge solubilization due to the disruption of extracellular polymeric substances structure and microbial cells. The biodegradability of released organic substance is also improved due to the oxidation of non-biodegradable substances. The activity of functional enzymes for hydrolysis and acidification is enhanced but that for methanogenesis is inhibited. Further analysis on microbial community structure indicates that phylum Firmicutes and genera Proteiniclasticum showed the maximal positive correlation with SCFA production, while the abundance of methanogenic archaea especially acetoclastic methanogenic archaea is inhibited by Fe 2+ /PAA treatment. Moreover, the presence of Fe 2+ lengthened the oxygen release period of PAA, the main functional reactive oxygen species are hydroxyl radicals and Fe 2+ facilitated PAA generates more hydroxyl radicals thus enhancing the oxidation ability of PAA.CONCLUSION: This study demonstrated that Fe 2+ /PAA can be used as an effective pretreatment method for SCFA accumulation in sludge anaerobic fermentation process. The findings obtained in this study will supply information for the application of Fe 2+ catalyzed PAA pre-oxidation in sludge treatment.
