Controlling pathogens and undesired biofouling in aquaculture or shipping activities is important due to the related potential economic and public health impacts. Accordingly, the treatment of seawater has increased interest in the maritime industry. Advanced Oxidation Processes are promising techniques for the treatment of different aqueous matrices. In this context, sulfate radical-based AOPs appear to be a good alternative for seawater applications. Consequently, the goal of this study is to evaluate the disinfection efficacy of combining the peroxymonosulfate salt ([PMS] = 1 and 5 mg L^-1) with an ozonation treatment. Different inactivation processes (O₃, PMS, and O₃/PMS) have been investigated with Vibrio alginolyticus as a target microorganism. In comparison with single ozonation, kinetic rates have been accelerated by 65% and 123% with the addition of 1 and 5 mg L^-1 of PMS, respectively. It results in a synergistic effect for the O₃/PMS combination. The transferred ozone dose is also notably reduced for reaching the 4 Log-removal value (O₃: 1.53 mg O₃ · L^-1; O₃/PMS: 0.87 mg O₃ · L^-1 (1 mg PMS·L^-1), and 0.59 mg O₃ · L^-1 (5 mg PMS·L^-1)). O₃/PMS treatment also presents a greater residual effect and higher acute toxicity of the treated effluent. Results obtained suggest the peroxymonosulfate as a good promoter of disinfection in the presence of O₃, not only by increasing the inactivation rate but also in minimizing bacterial regrowth, which implies greater cell damage during treatment processes. Thus, the O₃/HSO₅- process deserves further research as an alternative to traditional techniques for water treatment.

由于相关的潜在经济和公共卫生影响，控制水产养殖或运输活动中的病原体和不希望的生物结垢很重要。因此，海水的处理已引起海事行业的兴趣。先进的氧化工艺是用于处理不同水性基质的有前途的技术。在这种情况下，基于硫酸根的AOP似乎是海水应用的良好替代品。因此，本研究的目的是评估过氧化一硫酸盐（[PMS] = 1和5 mg L ^-1）与臭氧处理的组合的消毒效果。用解藻弧菌研究了不同的灭活过程（O ₃，PMS和O ₃ / PMS）作为目标微生物。与单次臭氧化相比，分别添加1和5 mg L ^-1的PMS，动力学速率分别提高了65％和123％。它对O ₃ / PMS组合产生协同作用。转移的臭氧剂量也显着降低，以达到4 Log-去除值（O ₃：1.53 mg O ₃ ·L ^-1 ; O ₃ / PMS：0.87 mg O ₃ ·L ^-1（1 mg PMS·L ^-1）和0.59 mg O ₃ ·L ^-1（5 mg PMS·L ^-1）。Ø ₃/ PMS处理还表现出更大的残留效应和更高的急性毒性。获得的结果表明，过氧一硫酸盐是存在O ₃时消毒的良好促进剂，不仅提高了灭活率，而且还使细菌的再生最小化，这意味着在处理过程中细胞损伤更大。因此，作为传统的水处理技术的替代方法，O ₃ / HSO _5-工艺值得进一步研究。
