UV-Ozone Water Oxidation/Sterilization Process.
Abstract
The purpose of this program was to determine the feasibility of purifying water using the combination of ozone and ultraviolet radiation. It was discovered from in-house efforts that this combination of purifying agents was an effective means of removing bacteria and organic contaminants in water. The initial objective of this program was to define the levels of ozone and UV radiation required to destroy predetermined concentrations of microbial contaminants and organic substances in water. These contaminants were representative of those often found in waste water effluents encountered by the Army and NASA. The study was divided into two parallel efforts, a microbiological study and an organic study. The microbiological investigation has shown that the combination of UV and ozone is more effective in destroying E. coli, Streptococcus faecalis, Klebsiella pnumoniae and Acanthamoeba castellanii than UV or ozone alone. In the organic tests, the test organic compounds selected were hydroquinone, pyrogallol, xylenol, sodium acetate and urea.
