“…Furthermore, a 0.8-1.6 mg/L concentration of PAA was proposed to be sufficient as a residual disinfectant [171]. PAA disinfection (at a dose of 4-5 mg/L and a contact time of 15 mins) was a promising method for the remediation of groundwater contaminated with sewage [172]. In another case, groundwater contaminated with wastewater required 2 mg/L of PAA and 10 minutes of contact time to eliminate fecal and total coliforms [173].…”

Peracids have gained interest in the water treatment over the last few decades. Peracetic acid (CH 3 CO 3 H) has already become an accepted alternative disinfectant in wastewater disinfection whereas performic acid (CHO 3 H) has been studied much less, although it is also already commercially available. Peracids have also been tested for drinking water disinfection, oxidation of aqueous (micro)pollutants, sludge treatment and ballast water treatment, to name just a few examples. The purpose of this review paper is to represent comprehensive up-to-date information about the water treatment applications, aqueous reaction mechanisms, and disinfection byproduct formation of peracids, namely performic, peracetic and perpropionic acids. and PFA have several of the qualities of an ideal disinfectant: toxicity to microorganisms, but not to higher forms of life; effectivity at ambient temperatures; stability and long shelf-life; low corrosivity; deodorizing ability; widespread availability and reasonable cost [12].PAA and PFA are colorless liquids with characteristic pungent odors. Both are thermodynamically unstable and can decompose spontaneously or explode when highly concentrated, heated, under mechanical stress or exposed to catalytic effects of impurities [1,13,14]. The recommended storage temperatures are below 30 and 20°C for PAA and PFA, respectively [6,14]. Longer carbon chain length increases stability, and thus PAA is more stable than PFA [1]. However, the O-O bond dissociation energy of PFA and PAA has been calculated to be similar: 48 kcal/mol [15]. Percarboxylic acids have typically pK a values 3-4 units higher than the parent carboxylic acids [1]. Nonetheless, PFA and PAA are corrosive [16]. ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 3Exposure to PAA and PFA causes irritation and possibly permanent damage to the skin (cutaneous emphysema), eyes and the respiratory system. In the skin contact, 0.2% is proposed as the no-observed-effect concentration (NOEC) for short and medium length exposure [17].When inhaled, airborne concentrations less than 0.16-0.17 ppm (0.50-0.52 mg/m 3 ) are considered to cause no irritation [17,18]. However, higher concentrations are harmful and a case study suggested that PAA could cause occupational asthma [19].The largest users of PAA on a global scale (estimated in 2013) are shown in Fig. 1. Similar numbers are not available for PFA, but it is probably used at significantly lower quantities.The largest user, the food industry, applies PAA as a disinfectant in fresh produce washing water, clean-in-place (CIP) processes, on food processing equipment, and in pasteurizers, to name just a few examples [21,22]. PFA is also a suitable disinfectant in low-temperature refrigerated food processing and storage rooms [23]. In healthcare, PAA is used for instance in Recently, methods to determine the residual PAA from wastewater were compared: the spectrophotometric method using DPD and catalase was recommended for 0.1-0.5 mg/L PAA concentrations and the cerimetric/iodometric titration...

“…PMS treatment of groundwater contaminated with E. coli and Enterococcus sp. yielded more than 3 log inactivation after 15 min of exposure time, using 4 mg/L of PMS (6.50 mM) (Bailey et al, 2011). Although Enterococcus is also a Grampositive like B. mycoides, higher concentrations of PMS are needed to inactivate more resilient Gram-positive such as the sporulated bacteria.…”

Inactivation of pathogenic microorganisms in freshwater using HSO5−/UV-A LED and HSO5−/Mn+/UV-A LED oxidation processes

Freshwater disinfection using photolytic and catalytic activation of peroxymonosulphate (PMS) through PMS/UV-A LED and PMS/M/UV-A LED [M = Fe or Co] processes was evaluated through the inactivation of three different bacteria: Escherichia coli (Gram-negative), Bacillus mycoides (sporulated Gram-positive), Staphylococcus aureus (non-sporulated Gram-positive), and the fungus Candida albicans. Photolytic and catalytic activation of PMS were effective in the total inactivation of the bacteria using 0.1 mM of PMS and M at neutral pH (6.5), with E. coli reaching the highest and the fastest inactivation yield, followed by S. aureus and B. mycoides. With B. mycoides, the oxidative stress generated through the complexity of PMS/M/UV-A LED combined treatments triggered the formation of endospores. The treatment processes were also effective in the total inactivation of C. albicans, although, due to the ultrastructure, biochemistry and physiology of this yeast, higher dosages of reagents (5 mM of PMS and 2.5 mM of M) were required. The rate of microbial inactivation markedly increased through catalytic activation of PMS particularly during the first 60 s of treatment. Co was more effective than Fe to catalyse PMS decomposition to sulphate radicals for the inactivation of S. aureus and C. albicans. The inactivation of the four microorganisms was well represented by the Hom model. The Biphasic and the Double Weibull models, which are based on the existence of two microbial sub-populations exhibiting different resistance to the treatments, also fitted the experimental results of photolytic activation of PMS.

“…In aquaculture, the compound is mainly used as a disinfectant and has been demonstrated to be active against pathogenic bacteria and other harmful micro‐organisms without causing toxicity to animals and the environment, owing to the low toxicity of by‐products (Rico et al, 2013; Sanchez‐Fortun et al, 2008; Wang, Guo, et al, 2020; Wang, Wu, et al, 2020). Previous studies have demonstrated the disinfection ability of potassium monopersulfate compound (KMPC), which can effectively control pathogens, such as Escherichia coli and Staphylococcus aureus in potable water (Bailey et al, 2011); S. aureus , hepatitis B virus and hepatitis C virus in hospitals (Matsuoka et al, 2017); and Vibrio harveyi , Ranavirus and Edwardsiella in aquaculture (Min et al, 2015; Paetzold & Davidson, 2011). Additionally, the chain reaction of KMPC in water can release oxygen and a variety of strong oxidation substances (Ermer & Röbke, 2003); Therefore, KMPC has been widely used in sewage and sludge treatment and appears to have the potential to degrade the organic material from shrimp faeces and feed.…”

In this study, limited water exchange was used to simulate small earthen ponds equipped with greenhouses for Penaeus vannamei culture by laying sediment in tanks, and we investigated the effects of treatment with potassium monopersulfate compound (KMPC) in multiple low‐dose (5 g/m3, three times every 2 weeks) and single high‐dose (15 g/m3, once every 2 weeks) on the culture environment and shrimp performance. The application of KMPC significantly increased the dissolved oxygen and decreased the ammonia nitrogen and nitrite nitrogen concentration in water. Further analysis of water micro‐organisms showed that the application of KMPC inhibited some micro‐organisms with anaerobic denitrification, and prevented the excessive accumulation of ammonia nitrogen and nitrite nitrogen in water. Compared with two different KMPC application methods, multiple low‐dose KMPC application improved water quality in a short time, and the growth state of shrimp perform better. However, the survival rate of shrimp was reduced under the single high‐dose KMPC application. Therefore, the KMPC application mode of multiple low‐dose is more suitable as a reference application method for daily cultural environment management. However, in this mode, micro‐organisms in water may be inhibited to a certain extent. Therefore, it is recommended to supplement probiotics when managing the culture environment for a long period.
