Abstract

An ultraviolet radiation/oxidation fluid decontamination apparatus is provided which includes a container made of high tensile strength material through which the fluid to be treated flows, a high intensity, directed beam light source, a small ultraviolet transparent window through which the directed beam propagates, and an oxidant injection port. The container interior is lined with a reflective surface which distributes the light throughout the container and a non-sticking surface which prevents fouling of the container. Organic contaminates are oxidized to carbon dioxide, water and other nonharmful products during the fluid treatment carried out by this apparatus.

Claims

1. A fluid decontamination apparatus which promotes oxidation of organic contaminants in said fluid comprising:

a reaction vessel through which fluid flows, said reaction vessel being composed of a high tensile strength alloy or steel material;

said reaction vessel having an interior surface, said interior surface being lined with a chemically inert, non-stick material, said material also being transparent to ultraviolet radiation;

said interior surface comprising a plurality of ridges wherein said chemically inert material covers said ridges, said ridges stabilizing placement of said chemically inert, non-stick material;

a window mounted on said reaction vessel, said window being transparent to ultraviolet radiation;

said window being protected from contact with said fluid by a window cover formed from said chemically inert, non-stick material, said material also being transparent to ultraviolet radiation;

an ultraviolet radiation source positioned so that said ultraviolet radiation propagates through said window; and

means for adding oxidant to said fluid.

2. The fluid decontamination apparatus of claim 1 further comprising:

an inflow source through which fluid enters said reaction vessel; and

an outflow pipe through which fluid exits said reaction vessel,

said outflow pipe and said inflow source being composed of a high tensile strength alloy or steel material.

3. The fluid decontamination apparatus of claim 2 wherein said reaction vessel has a reflective interior surface.

4. The fluid decontamination apparatus of claim 1 wherein said chemically inert material is fluorinated ethylene propylene.

5. The fluid decontamination apparatus of claim 4 wherein said ultraviolet radiation source produces a high intensity, directed light beam.

6. The fluid decontamination apparatus of claim 5 wherein said ultraviolet radiation source comprises a laser.

7. The fluid decontamination apparatus of claim 5 wherein said window comprises flare means to flare said high intensity, directed light beam as said light beam passes through said window.

8. A method of organic removal from a fluid comprising the steps of:

(a) providing a reaction vessel through which said fluid flows, said reaction vessel composed of a high tensile strength alloy or steel material;

said reaction vessel having an interior surface lined with a chemically inert, non-stick material, said material also being transparent to ultraviolet radiation;

said interior surface comprising a plurality of ridges wherein said chemically inert material covers said ridges, said ridges stabilizing placement of said chemically inert, non-stick material;

a window mounted on said reaction vessel, said window being transparent to ultraviolet radiation;

an ultraviolet radiation source positioned adjacent said window; and

,

means for adding oxidant to said fluid, and,

(b) passing said fluid through said reaction vessel,

(c) simultaneously exposing said fluid to radiation from said ultraviolet radiation source, and,

(d) adding oxidant to said fluid resulting in organic molecular disassociation by creating hydroxyl radicals.
