Abstract

Feedwater is treated using a combination of techniques, including the integration of a brine solution to promote the formation of reactive and molecular species in the feedwater with electrolytic ionization, the application of electromagnetic fields and the application of plasma fields. The integrated, combined techniques offer an improved treatment of scale forming ions, bacteria and biological contaminants in feedwater.

Claims

1. A system for treating feedwater comprising:

a brine treatment subsystem operable to add a brine solution into feedwater to promote the formation of reactive and molecular species in the feedwater;

an electrolytic ionization section operable to form an amount of ionized, dissolved metal ions in feedwater;

an electro-magnetic section operable to apply modulated electric and magnetic fields to the feedwater to effect the morphology of scale forming ions in the feedwater; and

a plasma section operable to apply plasma energy to the feedwater to form reactive and molecular species in the feedwater.

2. The system as in claim 1 wherein the brine solution comprises a mixture of sodium chloride and water.

3. The system as in claim 1 wherein the reactive and molecular species comprise mixed oxidants that exhibit chlor-oxygen chemistry.

4. The system as in claim 1 wherein the electrolytic ionization section comprises one or more positively charged and negatively charged electrodes.

5. The system as in claim 4 wherein the electrolytic ionization section comprises a power supply operable to supply the electrodes with a variable amount of power, wherein the electrodes are operable to form the amount of ionized, dissolved metal ions in the feedwater depending on the magnitude of the current supplied to the electrodes and upon the flow rate of the feedwater.

6. The system as in claim 4 further comprising one or more switches operable to reverse the polarity of the electrodes.

7. The system as in claim 1 wherein brine treatment subsystem comprises an in-line subsystem.

8. The system as in claim 1 wherein the brine treatment subsystem comprises an isolated subsystem.

9. The system as in claim 2 wherein the brine treatment subsystem comprises a heater operable to heat the brine solution to accelerate the dissolution of sodium chloride in the water.

10. The system as in claim 1 wherein the plasma section comprises a pulse width modulation/pulse density modulation section operable to insure a resonant frequency of the electric field is maintained to further insure the generation of a constant amount of mixed oxidants in the feedwater.

11. The system as in claim 1 wherein the plasma section is further operable to apply the plasma energy to the feedwater, and to produce hydrogen ions in the feedwater.

12. The system as in claim 1 wherein the plasma section is further operable to apply the plasma energy to the feedwater, and to produce hydrogen in the feedwater.

13. The system as in claim 1 wherein the plasma section is further operable to apply the plasma energy to the feedwater, and to produce ozone gas in the feedwater.

14. The system as in claim 1 wherein the plasma section is further operable to apply the plasma energy to the feedwater to, and to produce hydrogen peroxide in the feedwater.

15. The system as in claim 1 wherein the plasma section is further operable to apply the plasma energy to the feedwater, and to produce chlorine based reactive oxygen species in the feedwater.
