Abstract

A method of sterilizing water that includes: immersing at least one electrode unit having a negative electrode within a container and a positive electrode within the container, the positive electrode separated from and facing the negative electrode, wherein the negative electrode has a plurality of negative electrode projections thereon, and the positive electrode has a plurality of positive electrode projections thereon, each positive electrode projection arranged to face and be aligned with each negative electrode projection one by one; and, supplying direct current by at least one power supply to the electrode unit immersed under the water.

Claims

1. A method of sterilizing water comprising:

immersing at least one electrode unit having a negative electrode within a container and a positive electrode within the container, the positive electrode separated from and facing the negative electrode, wherein the negative electrode has a plurality of negative electrode projections thereon, and the positive electrode has a plurality of positive electrode projections thereon, each positive electrode projection arranged to face and be aligned with each negative electrode projection one by one; and

,

supplying direct current by at least one power supply to the electrode unit immersed under the water.

2. The method as claimed in claim 1, wherein the negative electrode and the positive electrode are formed as plate shape respectively.

3. The method as claimed in claim 1, wherein the water is a salt solution.

4. The method as claimed in claim 3, wherein the salt solution is normal saline.

5. The method as claimed in claim 1, wherein the negative electrode projections and the positive electrode projections are formed as one of cones having an acute end or pillars.

6. The method as claimed in claim 1, wherein the negative electrode projections and the positive electrode projections are formed or plated by one of platinum, titanium and carbons.

7. The method as claimed in claim 6, wherein the plated thickness on the negative electrode projections and on the positive electrode projections are formed more thickly than other area.

8. The method as claimed in claim 1, wherein one of the negative electrode projection and the positive electrode projection is formed as replaceable.

9. The method as claimed in claim 1, wherein the power supply is formed as at least one battery.

10. The method as claimed in claim 1, wherein the water is one of tap water, underground water and distilled water.

11. The method as claimed in claim 1, wherein the direct current is applied by controlling a switch to the electrode unit during a predetermined time.
