Özet

In this study, bacterial disinfection was investigated by using the sonolysis, photocatalysis and sonophotocatalysis processes. For this purpose, Vibrio cholerae Inaba NCTC 3661 strain was used throughout the study. Compared to sonolysis and photocatalysis, sonophotocatalysis was found to be the most effective on disinfection. In addition, different wavelengths (254 nm and 365 nm) of ultraviolet lamps (UV) were evaluated on disinfection. The wavelength of 254 nm was more effective than 365 nm on the disinfection. Moreover, the shortest disinfection time was measured as 8 minutes in sonophotocatalytic process at 254 nm wavelength.
