“…This phenomenon implies that the difference of treatment processes has little effect on the conversion of UV quenching substances (UVQS). This is strong evidence that the degradation of UVQS is dominated by direct ozone oxidation even under the condition of •OH exposure, which was also confirmed in •OH quenching experiments [2,40]. Nonetheless, various oxidation systems have effect on the degradation rate of UVQS, as reflected in Fig.…”

“…The ozonation process generally involves two primary reaction stages, corresponding to the instantaneous phase that the applied ozone dose (AOD) < initial ozone demand (IOD) and the gradual phase that AOD > IOD, respectively [39][40][41]. Due to the different reaction mechanisms, the mass transfer and decomposition rates of ozone differ in two stages.…”

“…After the fifth cycle, • OH scavenging experiments were conducted to study the role of both O 3 and • OH in HEDP oxidation. The commonly used • OH quencher tert -butyl alcohol ( t -BuOH) was spiked to the HEDP solution at a concentration of 200 mmol/L before starting the ozonation …”

“…In the late 1950s, studies on isothiazolinone compounds began. Since the 1960s, isothiazolinone biocides have been applied gradually in the industry [ 105 ]. The use of isothiazolone biocides alone or in combination with other biocides has an effective inhibitory effect on SRP under anaerobic conditions.…”
