Abstract
Aqueous solutions of ozone represent a promising alternative to chlorine-containing disinfectants, which has been confirmed by previous studies. Disinfection of surfaces, unlike bulk water, remains a poorly understood area. The article discusses the technical aspects of the use of ozone and hypochlorites, including ozone generation, dissolution in water, parameter control, ozone destruction, microbial inactivation efficiency and safety. The study results point to the benefits of using ozone. The formation of micro and nanobubbles during disinfection with ozone is also important. The ozone half-life of 20 minutes ensures high efficiency of inactivation of microorganisms and no need for subsequent destruction of residual ozone. Comparison with hypochlorites shows the significant superiority of ozone in inactivating microorganisms on various surfaces. This allows you to reduce disinfection time and reduce corrosion of materials. The economic indicators of using ozone are comparable to chlorine-containing reagents, while the environmental characteristics of ozone are much better. The study highlights the technical and environmental feasibility of using ozone to disinfect surfaces, providing important data for the development of appropriate technologies.
