Klebsiella Pneumoniae disinfection with ultrasound and hydrogen peroxides

Abstract

Water-borne epidemics caused by pathogenic microorganisms endanger public health especially in countries where access to clean water sources is difficult. Also, the conventional disinfection methods have various disadvantages on environmental health and they can be ineffective against some pathogenic microorganisms. For these reasons, the disinfection process applied in water has gained great importance and new alternative treatment technologies have to be developed to replace traditional methods used to protect public health. In this study, the effects of ultrasound (US) and hydrogen peroxide (H2O2), which have been used for water disinfection in recent years, have been examined whether or not they can remove Klebsiella pneumoniae from water. This study has concluded that the combination of US and H2O2 can effectively remove Klebsiella pneumoniae bacteria from water. When the application of ultrasound was performed with a H2O2 concentration of 5 mg l-1, the disinfection efficiency of Klebsiella pneumoniae was 4.22 log after 60 min.
