Abstract

The present disclosure provides for a system and method that intensely oxidizes water as it navigates through a system and accurately, controllably neutralizes the oxidation by-products before the water exits the system.

Claims

1. A process control oxidation water treatment system comprising:

a water source;

a main line in communication with said water source and having a main line injection point; and

a process stream flowing through the main line to an aeration tower;

wherein an ozone dispenser adds ozone to water in the main line at a main line injection point upstream of an aeration tower inlet of the aeration tower, the aeration tower being configured and arranged such that the water and ozone flow in an upward direction in the aeration tower from the aeration tower inlet to an aeration tower outlet at a top of the aeration tower, and a neutralizing chemical dispenser adds a sodium thiosulfate solution at the top of the aeration tower, and wherein the aeration tower outlet at the top of the aeration tower releases the water into a main reservoir.

2. The water treatment system of claim 1 wherein said water source is a location from which the process stream originates and flows through said main line and to which a sanitized process stream returns.

3. The water treatment system of claim 1, wherein a reaction being substantially 4O₃+2S₂O₃²⁻

+4OH⁻

→

4SO₄²⁻

+2O₂+2H₂O.

4. The water treatment system of claim 1, wherein said water source is at least one of a sea, a lake, a stream, an ocean, a storage tank, an aquarium, a swimming pool, a fountain, a river, a contaminated spill area, a delta, a swamp, a pond, channel, or canal.

5. The water treatment system of claim 1, wherein said process stream from said water source contains at least one contaminant or combination of contaminants, said at least one contaminant or combination of contaminants including at least one or any combination of color bodies, bacteria, viruses, fungi, natural bodily fluid of an organism or bodily secretion of an organism.

6. The water treatment system of claim 5, wherein said at least one contaminant or combination of contaminants originates from a food processing station.

7. The water treatment system of claim 1, wherein said process stream contains at least one of black or grey water.

8. The water treatment system of claim 7, wherein said black or grey water is produced onboard a watercraft.
