In this study, we investigated the use of ultrasound for the disinfection of process water as an alternative for more traditional techniques, like chlorination and UV-irradiation. A pilot plant was constructed to mimic circulating process water in industrial environments. The disinfection efficiency of ultrasound was assessed and compared to UV-treatment and chlorination. In addition, the operational costs for the different technologies were evaluated. Based on disinfection efficiency and operational costs, the pilot plant experiments indicate that chlorination is the method of preference to treat bacteria in suspension. In the prevention of biofilm formation, the results of UV irradiation and ultrasound are comparable, with a slightly higher energy consumption for the ultrasonic treatment. Finally, the use of ultrasound to prevent biofilms was also evaluated in an industrial environment (case study). The results obtained from the case study are in agreement with the results obtained from the pilot plant study. To our knowledge, this is the first study that evaluates the use of ultrasound technology for prevention of biofilm formation in realistic circumstances as encountered in an industrial environment.
在这项研究中，我们研究了将超声波用于消毒工艺水，以替代更为传统的技术，如氯化和紫外线照射。构建了一个中试工厂来模拟工业环境中的循环工艺水。评估了超声波的消毒效率，并将其与 UV 处理和氯化进行了比较。此外，还评估了不同技术的运营成本。基于消毒效率和运营成本，中试工厂实验表明，氯化是处理悬浮细菌的首选方法。在防止生物膜形成方面，紫外线照射和超声波的结果相当，超声波处理的能耗略高。最后，还在工业环境中（案例研究）评估了超声防止生物膜的应用。案例研究的结果与中试工厂研究的结果一致。据我们所知，这是第一项评估在工业环境中实际情况下使用超声波技术防止生物膜形成的研究。
