Water decontamination apparatus using peroxide photolysis ionizer
First Claim
1. For use in the treatment of water, apparatus comprising a first chamber, a water inlet port in fluid communication with said first chamber, a second chamber in fluid communication with said first chamber and having an outlet port, first orifice means in fluid communication with said second chamber for introducing oxidizing reagent into said second chamber, an ultraviolet radiation source operatively coupled to said first and second chambers, said ultraviolet radiation source being disposed to simultaneously irradiate water in said first chamber and water and reagent in said second chamber, and second orifice means for conducting and directing water from said first to said second chamber, said second orifice means directing the water toward a mixing zone, wherein the water and the reagent are mixed in said second chamber and irradiated by ultraviolet radiation from said radiation source.

Abstract
Apparatus and a method are disclosed for decontaminating water, using an ionizing reactor. Water contaminated by organic compounds is introduced into a chamber in which it is concurrently irradiated by microwave and an ultraviolet source to activate it by photolysis. The water is then introduced to a hydroxyl reactor chamber. An oxidizing reagent, such as hydrogen peroxide, is irradiated by subjecting it to the UV source. The activated water and irradiated oxidizing reagent are then vectored to a locus at which they are mixed under continuing UV radiation from the source. The apparatus and method may be incorporated into a water treatment system employing existing contaminant extraction techniques, such as immiscible fluids separation and turbo-aspirated sparging.

17. For use in the treatment of water, an ionizing reactor comprising a cylindrical body having a longitudinal axis and first and second coaxial chambers;
- a water inlet port operatively associated with said first chamber and angularly offset from said longitudinal axis so that a water stream entering said first chamber from said inlet port assumes therein a helical path;
a water outlet in fluid communication with said second chamber;
light conducting means in light transmitting association with said first and second chambers;
means associated with said second chamber for introducing into said second chamber a stream of oxidizing reagent, a source of ultraviolet radiation operatively coupled to said light conducting means so that the application of ultraviolet radiation to said light conducting means simultaneously irradiates water in said first chamber and water and reagent in said second chamber;
a first orifice directing water from said first to said second chamber, said orifice providing a plurality of convergent water streams directed toward a focal zone, a second orifice operatively associated with said first orifice for injecting reagent into said second chamber toward said focal zone, whereby ultraviolet radiation transmitted to said second chamber irradiates water and reagent in said second chamber. - View Dependent Claims (18)
