“…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.…”

Phosphonates are widely used in industrial and household applications. Phosphorus (P) removal and recovery from phosphonates in wastewater require a (cost-)efficient process. This study developed a two-step approach for this challenge. In the first step, lava rock and expanded clay aggregates (ECA) were used to build two packed O 3 bubble columns (LBC and EBC, respectively) and were compared with a nonpacked bubble column (BC). After 90 min of ozonation, the net production efficiency of orthophosphate (Ortho-P) from a commonly used phosphonate in the textile industry [1-hydroxyethane-1,1-diphosphonic acid (HEDP)] was higher in the LBC (66%), followed by the BC (59%) and EBC (44%). The lowest Ortho-P production efficiency in the EBC was because a high fraction of the produced Ortho-P was adsorbed on the surface of the ECA. However, when the adsorptive packing materials were reused during five consecutive ozonation cycles, the Ortho-P adsorption sites on the packing materials tended to be saturated. As such, the net production efficiency of Ortho-P in the LBC and EBC increased to 86 and 72%, respectively. In the second step, iron-coated sand granules were used to adsorb and recover the produced Ortho-P. Higher Ortho-P recovery efficiencies (66.4% for the LBC and 61.9% for the EBC) and Ortho-P sorption capacities (12.05 mg/g for the LBC and 8.13 mg/g for the EBC) were achieved in combination with packed-bed ozonation. This study provides insights into HEDP removal from wastewater and the recovery of Ortho-P as a valuable resource, which fits within the development of sustainable wastewater treatment processes.

“…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.…”

A microbiologically influenced corrosion (MIC) causes huge economic losses and serious environmental damage every year. The prevention and control measures for MIC mainly include physical, chemical, and biological methods. Among them, biocide application is the most cost-effective method. Although various biocides have their own advantages in preventing and treating MIC, most biocides have the problem of polluting the environment and increasing microorganism resistance. Therefore, it has stimulated the exploration of continuously developing new environmentally friendly and efficient biocides. In this review, the application advantages and research progress of various biocides used to prevent and control MIC are discussed. Also, this review provides a resource for the research and rational use of biocides regarding MIC mitigation and prevention.
