Description:The oxidation of dilute concentrations of organics in aqueous solutions using hydrogen peroxide and/or ozone as the oxidant in the presence of ultraviolet (UV) light has been demonstrated and is offered commercially be several corporations. Present systems seem to be limited to low concentrations of organics ( less than 10 ppm), if costs are to be maintained at less than a few dollars per thousand gallons of water treated. Further, oxidation is often not complete and low molecular weight acids, aldehydes, and ketones may remain in the treated water as final oxidation products.
Improved photochemical reactor design using low life-cycle cost UV sources is proposed. The reaction system will exploit newly discovered oxidation chemistry which leads to the complete oxidation of unsaturated organics in aqueous streams.
