Abstract

Abstract A non-polluting wastewater evaporation disposal method and system wherein hydrogen gas is electrolytically produced from the wastewater, collected and used as a source of fuel to evaporate the wastewater to thereby convert the wastewater to a disinfected non-polluting sterile solid residue and water vapor. A halogen having an atomic number of between 16 and 54 may also be electrolytically produced from the wastewater and used to disinfect the wastewater.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 130 words
A non-polluting method for disposing of waste-water comprising: bringing said wastewater into a liquid-retaining cell having an anode and cathode therein and into contact with an anode and cathode. passing an electric current through said wastewater in said cell and between said anode and cathode thereby producing hydrogen gas at the cathode and a halogen at said anode; keeping the hydrogen gas separate from the chlorine gas; bringing said halogen into intimate contact with said wastewater in said cell to disinfect and said wastewater; collecting said hydrogen gas; removing said wastewater after contact with said halogen from said cell; and evaporating said wastewater using said collected hydrogen gas as a source of fuel to convert the removed wastewater from said cell into disinfected non-polluting sterile solid residue and water vapor.
Claim 2
Dependent Claim 130 words
A non-polluting method for disposing of waste-water comprising: bringing said wastewater into a liquid-retaining cell having an anode and cathode therein and into contact with an anode and cathode. passing an electric current through said wastewater in said cell and between said anode and cathode thereby producing hydrogen gas at the cathode and a halogen at said anode; keeping the hydrogen gas separate from the chlorine gas; bringing said halogen into intimate contact with said wastewater in said cell to disinfect and said wastewater; collecting said hydrogen gas; removing said wastewater after contact with said halogen from said cell; and evaporating said wastewater using said collected hydrogen gas as a source of fuel to convert the removed wastewater from said cell into disinfected non-polluting sterile solid residue and water vapor.
Claim 3
Dependent Claim 42 words
In the method of claim 1 wherein said wastewater contains a halogen-containing salt, the halogen having an atomic number of between 16 and 54, said method further comprising the step of producing the same halogen as in said salt at said cathode.
Claim 4
Dependent Claim 37 words
In the method of claim 1 including the step of adding a halogen-containing salt, the halogen having an atomic number of between 16 and 54, to said wastewater prior to passing said electric current through said wastewater.
Claim 5
Dependent Claim 21 words
In the method of claim 3 including the step of producing the same halogen as in said salt at said anode.
Claim 6
Dependent Claim 143 words
A non-polluting method for disposing of the output of waste matter discharged from a recirculating toilet system using as a flushing medium a recirculating flushing fluid, the method comprising the steps of: bringing said waste matter into contact with an anode and a cathode in a liquid-retaining cell; passing an electric current through said waste matter and between said anode and cathode thereby producing hydrogen gas at the cathode and a halogen at said anode; collecting said produced hydrogen gas; bringing said waste matter in said cell into intimate contact with said halogen produced at said anode to disinfect said waste matter; removing said waste matter from said cell after contact with said halogen; and evaporating said wastewater using said collected hydrogen gas as a source of fuel to convert the removed waste matter into disinfected non-polluting sterile solid residue and water vapor.
Claim 7
Dependent Claim 143 words
A non-polluting method for disposing of the output of waste matter discharged from a recirculating toilet system using as a flushing medium a recirculating flushing fluid, the method comprising the steps of: bringing said waste matter into contact with an anode and a cathode in a liquid-retaining cell; passing an electric current through said waste matter and between said anode and cathode thereby producing hydrogen gas at the cathode and a halogen at said anode; collecting said produced hydrogen gas; bringing said waste matter in said cell into intimate contact with said halogen produced at said anode to disinfect said waste matter; removing said waste matter from said cell after contact with said halogen; and evaporating said wastewater using said collected hydrogen gas as a source of fuel to convert the removed waste matter into disinfected non-polluting sterile solid residue and water vapor.
Claim 8
Dependent Claim 51 words
In the method of claim 5 including the step of adding a halogen-containing salt, the halogen having an atomic number of between 16 and 54, to said waste matter prior to the step of passing an electric current therethrough thereby producing the same halogen as in said salt at said anode.
Claim 9
Dependent Claim 110 words
A non-polluting method for disposing of wastewater containing a halogen-containing salt, the halogen having an atomic number of between 16 and 54, to a sterile solid residue and water vapor comprising the steps of: electrolytically producing a halogen and hydrogen gas in a halogen salt containing cell and preventing said hydrogen gas from contacting said halogen; mixing said produced halogen in situ with said wastewater to disinfect said wastewater; collecting said hydrogen gas; burning said hydrogen gas; and purifying said wastewater after mixing with said halogen until said wastewater is converted to both a sterile solid residue and water vapor using the burning hydrogen gas as a source of fuel.
Claim 10
Dependent Claim 110 words
A non-polluting method for disposing of wastewater containing a halogen-containing salt, the halogen having an atomic number of between 16 and 54, to a sterile solid residue and water vapor comprising the steps of: electrolytically producing a halogen and hydrogen gas in a halogen salt containing cell and preventing said hydrogen gas from contacting said halogen; mixing said produced halogen in situ with said wastewater to disinfect said wastewater; collecting said hydrogen gas; burning said hydrogen gas; and purifying said wastewater after mixing with said halogen until said wastewater is converted to both a sterile solid residue and water vapor using the burning hydrogen gas as a source of fuel.
Claim 11
Dependent Claim 35 words
The method of claim 7 wherein the step of disinfecting said wastewater includes the step of agitating said wastewater while adding said halogen thereto thereby macerating said wastewater and mixing said halogen into contact therewith.
Claim 12
Dependent Claim 87 words
The method of claim 7 wherein the step of producing halogen and hydrogen gas includes the steps of: bringing said wastewater into an electrolytic cell having at least one anode and one hollow cathode therein; sealing said hollow cathode from entry of solid and gas particles into the interior thereof; bringing said wastewater into contact with said anode and said cathode; applying an electrical current to said anode and said cathode; and forming halogen in said cell while limiting hydrogen gas to the interior of said cathode.
Claim 13
Dependent Claim 22 words
The method of claim 7 wherein the step of burning said hydrogen gas includes the step of continuously burning said hydrogen gas.
Claim 14
Dependent Claim 39 words
The method of claim 7 wherein the step of pyrolyzing said wastewater includes the step of diverting at least a portion of said solid residue back into contact with said wastewater prior to producing said halogen and hydrogen gas.
Claim 15
Dependent Claim 22 words
The method of claim 7 including the step of focusing the heat of said burning hydrogen gas into contact with said wastewater.
