Abstract: A disinfection system includes at least one ozone generator; at least one ozone concentration level detector; programmable timer; at least one presence detector; at least one main system process management tool; at least one intermediate system process management tool. This invention aims not only to disinfect the air by removing unpleasant odour, but also to disinfect wastewater, premises and facilities by adjusting ozone concentration. Thus, not only the consequence of bad odour, which appears due to bacteria, protozoa, moulds and other fungi, but also the cause for occurrence of such bad odour is eliminated by exterminating viruses, bacteria, fungi, mould and all the main biogases within the disinfected environment. Modifications of this invention allow adjusting ozone concentration in order to disinfect premises and environment by avoiding possible hazardous ozone impact on people, working in the environments to be disinfected or residing near to such environments.

Abstract: The escalator handrail decontamination system includes at least one sealed decontamination unit, for safe and localized decontamination environment, including at least one ozone generator, at least one ozone concentration sensor at the decontamination zone, at least one ozone destruction unit for converting ozone to oxygen; at least one ozone safety sensor for monitoring ozone level in the area surrounding the moving handrail belt; at least one secondary ozone destruction unit downstream of the at least one safety sensor; an intermediate controller and a central controller. The ozone output from the EHDS ozone generator is constantly monitored by an ozone concentration sensor to ensure minimum efficacy levels of ozone are maintained and to ensure ozone output remains within designated safety levels. The EHDS is positioned at the unseen lower section of the revolving handrail.
