Ozone Contactor

A disinfection study was carried out in a continuous flow system employing different sizes of ozone bubbles to determine their effects on solubility of ozone, its utilization and inactivation of microorganisms. The bubble sizes were varied by changing the porosity of the diffusers and ozone flow rates through the ozone contactor. Natural bacterial population (standard plate counts) present in the secondary wastewater effluent, was enumerated before and after ozonation. It was found that for a given concentration of ozone at a constant gas flow rate, decrease in bubble sizes resulted in an increase in ozone residual and degree of inactivation of organisms inspite of a decrease in ozone utilization by the wastewater.
