The present study evaluated inactivation efficiency of a sonophotocatalytic process using ZnO nanofluids including ultrasonic parameters such as power density, frequency and time. The result showed that inactivation efficiency was increased by 20% when ultrasonic irradiation was combined with photocatalytic process in the presence of natural light. Comparison of inactivation efficiency in photocatalytic,...
Because of the excellent properties and wide applications on nanomaterials, recent years, researchers start to focus on the use of nanomaterials in wastewater treatment. This paper introduces the application of nano-sized ZnO in wastewater treatment. Advantages of nanomaterials and the possible antimicrobial mechanisms of nano-sized ZnO are presented in this paper. This paper concluded previous work...
This work investigated the antimicroorganism activities of ZnO, TiO2, MgO and SiO2 nanoparticles suspensions at different pH values. In this work, E. coli was used as model bacteria to test the antimicroorganism activities of these nanoparticles suspensions. Growth curves investigation with and without these nanoparticles suspensions was used to examine the antimicroorganism activities. The results...
