Water Disinfection With Advanced Methods: Successive and Hybrid Application of Antibacterial Column With Silver, Ultrasound and Uv Radiation
MetadataShow full item record
The disinfection process is of great importance to the water supply to prevent diseases spread by water. Due to its negative impacts on human health, the number of studies conducted on disinfection systems alternative to chlorination and similar traditional methods has been increased. Successive and hybrid systems that are highly efficient in inactivating the pathogenic microorganisms that may be present in water are being developed. In this study, the disinfection efficiency of the antibacterial filled column, ultrasonic reactor and UV reactor that we developed was increased by the successive and hybrid usage of the methods when Escherichia coli bacteria were used to detect the disinfection efficiency of the systems. In single disinfection studies, bacterial inactivation efficiency occurred in UV process was higher than antibacterial column and also, efficiency occurred in antibacterial column was higher than ultrasonic reactor. Triple hybrid usage of these systems resulted in an 8 log microbial inactivation reducing single treatment disadvantages of these systems. Furthermore, the flow speed and temperature effect were examined during the studies, and it was observed that the temperature had a positive effect on the hybrid system.
