Abstract

method and system for decomposing organic compounds in wastewater that uses an interaction between an acid, a permeable structure and ultra violet light to accelerate the decomposition of organic compounds in wastewater. This invention can be used to decomposing organic compounds in industrial process and wastewater discharges, municipal drinking water supplies, food processing rinse water and commercial and residential water purification systems.

Claims

1. A method for removing organic compounds, comprising:

A. receiving a flow of contaminated water;

B. introducing to said flow of contaminated water an acid;

C. passing said acid and contaminated water through a porous structure, wherein said porous structure is a light and water permeable disk comprising alumina;

D. illuminating said acid and contaminated water with light; and

E. decomposing organic compounds in said contaminated water to produce a decontaminated water flow; and

F. releasing said decontaminated water flow.

2. A method for removing organic compounds, as recited in claim 1, wherein said introduced acid is selected from the group consisting of peracetic acid and perchloric acid.

3. A method for removing organic compounds, as recited in claim 1, wherein said porous structure is further composed of TiO₂.

4. A method for removing organic compounds, as recited in claim 1, wherein said light is ultra violet light.

5. A method for removing organic compounds, as recited in claim 1, wherein said light is strobed or intermittent light.

6. A method for removing organic compounds, as recited in claim 1, wherein the decomposing organic compounds in said contaminated water to produce a decontaminated water flow comprises accelerating a rate of reaction of the organic compounds.
