Development of ozone sterilization system based microcontroller for E. Coli bacteria sterilization

It has been created microcontroller-based ozone sterilization system which is used for E. Coli bacteria sterilization. The created system consists of a neon sign transformer, corona electrode, ozone gas chamber container and ozone gas metering systems. Neon sign transformer and corona electrode are then assembled into an ozone generator that works on the principle of corona discharge. The use of ozone generators is controlled by microcontroller system. Ozone gas is produced by ozone generators which housed in a chamber and equipped by ozone gas indicator. The results of ozone gas effect testing in E. Coli with varied exposure of 15, 30 and 45 minutes showed the decrease number of E. Coli colonies of tested bacteria samples compared to the control sample without ozone gas exposure.
