The removal of bacteria from water is a highly important process for drinking water and sanitation systems especially on growing outbreaks of water borne diseases. The aim of this study was to evaluate the water disinfection efficiency of ZnO nanoparticle synthesized by solution combustion method (SCM). The ZnO nanoparticle, as a disinfectant, was prepared by the SCM. The prepared disinfectant was characterized by scanning electron microscopy, X-ray diffraction, and Brunauer-Emmett-Teller. The disinfection efficiency of the synthesized ZnO nanoparticle was evaluated using Escherichia coli as an indicator organism by disk diffusion, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) tests. The results show that the synthesized ZnO nanoparticle showed an average size of 15nm. The MIC and MBC of ZnO nanoparticle were 8 and 16gmL(-1), respectively. These results suggest that ZnO nanoparticle prepared by SCM could be used as an effective disinfectant, making this approach applicable to water-control systems.
