Development of multi-purpose portable air ozonator based on surface dbd

In this paper we describe a compact, economical, easy to use air ozonator developed at the Institute of Plasma Physics of the NSC KIPT and manufactured in collaboration with Public Joint Stock Company "HARTRON-PLANT" LtD. Ozonator of OzD 10/0.1-type uses a surface dielectric barrier discharge to generate ozone from flowing air oxygen, has a flexible system of settings, and is an autonomous and mobile sanitary device for the disinfection of closed spaces up to 500 m3. The output ozone concentration reaches 0.1 g/m3 with productivity of 10 g/h. A microprocessor controller has been developed to control the operation of the ozonator. The results of bacteria inactivation in two various premises for surgical operations are presented. (author)
