Abstract

A liquid desalination system is disclosed. The liquid desalination system includes a feed line having an inlet to receive liquid and an outlet to discharge the liquid. The liquid desalination system includes a magnet coupled to the feed line, the magnet to generate an oscillating magnetic field within the feed line and in opposition to the feed water flow. The removal of targeted ions can be achieved by manipulating the frequency and rate of the generated electromagnetic waves. The generated electromagnetic waves can be tuned to weaken the hydration bonds of that specific ion and facilitate its removal. The liquid desalination system generates an electric field across the feed line to enable the liquid to flow through the electric field. The electric field may attract sodium ions to a positive electrode and may attract chloride ions to a negative electrode, to desalinate the liquid in the feed line.

First claim

What is claimed is:

1. A liquid desalination system, comprising:
a feed line having an inlet to receive liquid and an outlet to discharge the liquid;
a magnet coupled to the feed line, the magnet to generate a magnetic field within the feed line and in parallel to the feed line; and
an electric field generator coupled to the feed line to generate an electric field across the feed line and to enable the liquid to flow through the electric field, the electric field generator being positioned downstream of the magnet.

2. The liquid desalination system of claim 1 , wherein the magnetic field is an oscillating magnetic field.

3. The liquid desalination system of claim 1 , wherein a polarity of the magnetic field is opposite to a direction of flow of the liquid.

4. The liquid desalination system of claim 1 , wherein the feed line includes an external surface, wherein the magnet is coupled to the external surface of the feed line.

5. The liquid desalination system of claim 1 , wherein the magnet is an electromagnet.

6. The liquid desalination system of claim 1 , wherein the electric field generator includes a first electrode and a second electrode.

7. The liquid desalination system of claim 1 , wherein the feedline is an antiferromagnetic material.

8. The liquid desalination system of claim 6 , wherein the first electrode and the second electrode are at least partially positioned within an interior surface of the feed line.

9. The liquid desalination system of claim 6 , wherein a voltage potential from the first electrode to the second electrode is at least 1.2 volts.

10. The liquid desalination system of claim 6 , wherein the first and second electrodes are porous.

11. The liquid desalination system of claim 6 , wherein the first and second electrodes are at least partially constructed of carbon.

12. A method of desalinating liquid, comprising:
directing liquid through an inlet of a feed line to cause the liquid to pass through the feed line and to exit an outlet of the feed line;
generating a magnetic field within at least part of the feed line, wherein the magnetic field is parallel to a direction of flow of the liquid; and
generating an electric field across the feed line downstream of the magnetic field, wherein the electric field is perpendicular to the direction of flow of the liquid.

13. The method of claim 12 , wherein generating the magnetic field includes generating the magnetic field with an electromagnet exposed externally to the feed line.

14. The method of claim 12 , wherein a polarity of the magnetic field is positive to negative in opposition to the direction of the flow of the liquid.

15. The method of claim 12 , wherein the magnetic field includes magnetic field waves and is an oscillating magnetic field.

16. The method of claim 12 , wherein generating the electric field includes generating the electric field with a first electrode and a second electrode disposed on opposite sides of the feed line, wherein the method further comprises positioning the first electrode and the second electrode at least partially within the feed line.

17. A computer-readable storage device having stored thereon instructions that when executed by one or more processors result in operations comprising: the method according to claim 12 .

18. A device comprising means to perform the method of claim 12 .
