Efficiency Evaluation of Developed Ozone System in Microorganism Treatment

Abstract

Ozone generator system using negative coronas was fabricated to produce ozone gas and ozonated water of varying concentration. The generated ozone air will be emitted to the water through bubble diffuser or venturi injection depending on the input air mass transfer rate. The concentration of ozonated water was examined using both ozone test strip and schoenbein paper. The efficiency of ozone gas in microorganism treatment is verified through the lowest number of microorganism’s colony available compared with other treatment methods. The half-life of ozonated water in this study was improved by increasing the transfer rate of water and solubility of ozone in water. Concentration of ozonated water was found increased through the application of pressurized oxygen input gas.
