Waste water treatment to reduce BOD/COD

1. A method of reducing a BOD or COD value of waste water having organics therein, and using high temperatures in a waste water treatment system to decompose the organics, comprising:

straining the waste water to remove particulate matter;

heating the filtered waste water in a tubing using a heater to produce hot waste water at a temperature greater than about 300 degrees F. to break down the organics thus destroying the food for bacteria;

coupling the hot water from said tubing to a variable-orifice nozzle where at least a portion of the water content of the hot water flashes into steam and any particulate matter in the hot water passes through said nozzle;

pumping the strained waste water through said tubing and to said nozzle with a pressure sufficient to prevent premature flashing of the hot water in the tubing into steam when heated by said heater, and using said nozzle as a restriction so that the hot water can be pressurized in said tubing;

maintaining the hot water in said tubing at the temperature and the pressure for a sufficient time to assure that at least one of the organic matter is broken down or a concentration of calcium in solution is reduced;

selecting a length of the tubing and selecting a pressure of the hot water so that the hot water remains in said tubing said sufficient time; and

condensing the steam into distilled water.

2. The method of claim 1 , further including

using the steam resulting from the flashing of the water content to preheat the waste water input into said waste water treatment system.

3. The method of claim 2 , further including disposing of volatile organic compounds (VOC) by vaporizing the VOC when the hot water is flashed into steam.

4. The method of claim 1 , further including heating the hot water sufficiently to destroy bacteria and viral organisms.

5. The method of claim 1 , further including reducing BOD and COD without vaporizing the hot water.

6. The method of claim 1 , further including oxidizing chemical compounds using ozone.

7. A method of softening waste water in a waste water treatment system to remove dissolved calcium and dissolved salt, comprising:

using a burner in the waste water treatment system to heat the waste water to a temperature sufficient to cause the dissolved calcium to precipitate into particulate calcium, and to a sufficient temperature to flash at least a portion of the water content of the waste water into steam;

separating the particulate calcium from the heated waste water in a first stage for disposal of the particulate calcium to thereby produce processed waste water with reduced calcium;

forcing the heated processed waste water through a nozzle in an expansion chamber at about atmospheric pressure in a second downstream stage to flash at least a portion of the water in the heated processed waste water into steam and to precipitate the dissolved salt into salt crystals in the expansion chamber;

extracting the salt crystals from the expansion chamber and disposing of the salt crystals separately from the particulate calcium;

condensing the steam into a purified form of distilled water and using the distilled water so as not to pollute the environment;

and

whereby the waste water which includes both calcium and salt is processed through said treatment system in one pass, but the calcium and the salt are separated in different stages of the system, and a purified form of distilled water is produced.

8. The method of claim 7 , further including precipitating the dissolved calcium without using chemicals, minerals or vaporization.

9. The method of claim 7 , further including transferring the waste water to a top of a top down tubing coil so that the particulate calcium falls to the bottom of the tubing coil and does not require lifting upwardly in the tubing coil.

10. The method of claim 7 , further including heating the processed waste water to a temperature that flashes a portion of the water into steam and the remaining unflashed water has an increased concentration of salt crystals, and recycling a mixture of unflashed water together with the salt crystals, and flashing the mixture in the expansion chamber to thereby further increase the concentration of the salt crystals in the expansion chamber.

11. The method of claim 7 , further including heating the waste water to a temperature of at least 300 degrees F. so that the dissolved calcium is precipitated and so that at least a portion of the water content flashes into steam and the dissolved salt precipitates into salt crystals.

12. A method of treating waste water in a waste water treatment system to achieve zero discharge, comprising:

straining the waste water to remove particulate matter;

heating the waste water with a source of heat that does not emit environmentally polluting emissions;

heating the waste water in an enclosure to a temperature greater than about 212 degrees F. to destroy and remove contaminates therefrom;

removing solid contaminants created during the heating of the waste water;

pressurizing the waste water in the enclosure so that a boiling temperature of the waste water is increased to prevent premature flashing of water in the enclosure;

processing the waste water through a nozzle located in an expansion chamber having a pressure therein that is about atmospheric pressure so that at least a portion of the water content of the heated and pressurized waste water flashes into steam, whereby the flashing of the waste water causes dissolved salts to precipitate in said expansion chamber so that a byproduct thereof is steam;

processing the steam in at least one of a) using the steam in an industrial process, or b) processing the steam through a condenser to produce distilled water;

collecting solid waste and sludge from a bottom of the expansion chamber;

disposing of the particulate matter, the solid contaminants, salts, solid waste and sludge without discharging the same down an industrial sanitary drain; and

using the distilled water in an industrial application without discharging the distilled water down the sanitary drain.

13. The method of claim 12 , further including using hydrogen as a fuel as a source of heat when combusted with oxygen.

14. The method of claim 12 , further including using heat generated by solar means as said source of heat.

15. The method of claim 14 , further including using said solar means to generate electricity for generating hydrogen.

16. The method of claim 12 , further including reducing emissions by incinerating environmentally hazardous materials, and scrubbing flu gasses in an incinerator with the water.

17. The method of claim 12 , further including incinerating volatile organic compounds and then scrubbing the incinerated gasses with the water.

18. The method of claim 12 , further including collecting any bio sludge and processing the biogas sludge to produce biogas, and using byproducts thereof for a fertilizer.

19. The method of claim 18 , further including burning any solid waste from a biodigester to generate at least one of heat or charcoal or fertilizer.

20. The method of claim 1 , further including processing the waste water without using bacterial agents or chemicals or minerals thereto during processing the waste water.

21. The method of claim 7 , further including using the steam in a heat exchanger to heat the feed water to a first temperature so that the calcium is precipitated and removed, and then heating the processed feed water with reduced calcium to a second higher temperature and forcing it through said nozzle to flash the water content in the processed feed water into steam and also to precipitate the dissolved sodium into salt crystals in said expansion chamber, whereby the second higher temperature processed feed water provides a higher saturation level of the salt crystals.

22. The method of claim 7 , further including generating unflashed water with one of dissolved salt or salt crystals therein to form a salt solution, and recycling the salt solution with the hot water and flashing the same to further concentrate the salt solution.

23. The method of claim 7 , further including passing the precipitated calcium through said nozzle and extracting the particulate calcium from said expansion chamber.
