Abstract

Bu çalışmada, atık suların mikroorganizmalardan arıtımı için alternatif olan ve son zamanlarda dikkat çeken
yöntemler kullanılmıştır. Bu amaçla özellikle atık sularda yer alan Salmonella typhi RSHMB 96051 bakterisinin
giderimi sonoliz, fotokataliz ve sonofotokataliz yöntemleri kullanılarak incelenmiştir. Yapılan denemelerde farklı
ışık şiddetlerinin bakteri giderimindeki etkileri bu prosesler üzerinde çalışılmıştır. Denemelerde ultrases enerjisi ve
ultraviyole ışınlar hem ayrı ayrı hem de eşzamanlı olarak birlikte kullanımlarıyla yapılmıştır. Bu prosesler sırasıyla
sonoliz, fotokataliz ve sonofotokataliz prosesleridir. Elde edilen sonuçlar karşılaştırıldığında her üç tekniğin de
bakteri gideriminde oldukça etkili olduğu ancak fotokataliz ve sonolizin birlikte kullanılmasıyla olan etkinin en
fazla olduğu tespit edilmiş ve bu yöntemle %100 giderime yaklaşık 6 dakika gibi kısa bir sürede ulaşıldığı tayin
edilmiştir.

The Usage of Sonophotocatalytic Process for the Disinfection of Bacteria

Abstract

In this study, some of the alternative methods have been utilized for the disinfection of
microorganisms in the waste water. The disinfection of Salmonella typhi RSHMB 96051 bacteria in the waste water
was investigated using the sonolysis, photocatalysis and sonophotocatalysis processes. In experiments, the effects
of different light intentities have been investigated with the processes mentioned above. The ultrasound energy and
ultraviolet light were used seperately and together as well. These processes are called sonolysis, photocatalysis and
sonophotocatalysis respectively. The results yielded that all the processes were quite effective. The simultaneous
use of sonolysis and photocatalysis yielded the best results. 100% disinfection ratio was obtained within 6 minutes
in this study
