Abstract
Sintered Wave Multi-Media Polarity Conversion Treatment Apparatus and Process is disclosed, which uses a non-destructive physiochemical PFAS vapor emissions treatment system to provide vacuum and vapor conveyance for 1) a Polarity Conversion Unit for non-destructive PFAS removal from soil, sludges, rechargeable galvanic filter media and objects, 2) a fluids treatment line for PFAS removal from water, brines, foams and colloids, and 3) an amphiphilic decontamination wand for PFAS removal from hard surfaces. The vapor emissions treatment system uses direct spray cooling to cool treatment gases where fluid chemistry causes pre-micellular aggregates/liquids crystals formation. Filtered aggregates are dried in a Brine Pot Evaporator for off-site disposal. Residual PFAS vapors are removed through a Vapor Phase Galvanic Separator where galvanic currents offer high energy interfaces of varying charges for monomeric PFAS self-assembly. The Polarity Conversion Unit assembly uses transportable flow through vessels, static geometry, high surface area, treatment gas temperature and velocity modulation to reduce thermal resistivity of the media. Treatment gas is sequentially routed around shaped vertical media beds where thermal energy disorganizes surface polarities (Gibbs free energy) disconnecting amphiphilic compounds/mixtures from the media. The fluids treatment line uses a Surface Excess Concentrator where a surface excess complex is created, removed and dried for off-site disposal. Treated bulk fluids exit from the bottom (below the surface) and are routed to the Aqueous Phase Galvanic Separator. Galvanic filter media is recharged in the Polarity Conversion Unit for reuse. Hard surfaces are decontaminated using the amphiphilic decontamination wand to disorganize surface polarity. Catalytic oxidation and granular activated carbon systems are also used to capture, destroy and measure classic contaminants and cleaved hydrocarbons from fluorinated precursors during treatment.

DETAILED DESCRIPTION OF THE INVENTION
Preferred Embodiment
1. Overview
[0242] The Cover Sheet presents a perspective view of the preferred embodiment of the Sintered Wave Multimedia Polarity Conversion Apparatus and Process.
[0243] The Polarity Conversion Unit (1) provides a means to use a contained arrangement to treat soils, sludges, rechargeable galvanic filter media, and objects. Treatment gases (air) are drawn into the apparatus through a blower(s) (2), which then delivers the air to an electric heater(s) (3). The blower (2) and heater (3) work in conjunction to modulate temperature and velocity delivered into the Polarity Conversion Unit.
[0244] There are a number of blower (2) and heater (3) assemblies mounted on top of the Polarity Conversion Unit. Only selected blower (2) and heater (3) assemblies are in operation at any given time providing focused treatment gas delivery to small sections delivered sequentially across the Polarity Conversion Unit (1). Blower (2) and Heater (3) assemblies are isolated from the Polarity Conversion Unit (1) when not in operation by a Blower/Heater assembly Isolation Damper (43). The blower (2) and heater (3) assemblies operate in tandem with the Modified Sintercraft Pad (4) where an individual extraction line (5) can be isolated with an Vapor Extraction Isolation Damper (6). The Vapor Extraction Manifold (7) connects an individual Vapor Extraction Line (5) to the apparatus vapor extraction system and Vapor Line Assembly through the main Vapor Extraction Line to Emissions Treatment (46). The Soil Slip assembly that contains soil, sludge, galvanic filter media or objects are placed inside the Polarity Conversion Unit (1) for treatment through the Access Doors (105) are not shown in
[0245] As part of the emissions treatment, a Cyclone Dust Separator (8) removes any fugitive dusts that escaped the Polarity Conversion Unit (1). In the event that soils or sludges contain PFAS and Hydrocarbon as co-contaminants the Catalytic Oxidizer Bypass Damper (9) causes the treatment gases to flow through the Electric Catalytic Oxidizer (10) in order to destroy and measure hydrocarbons or cleaved hydrocarbons. An Electric Catalytic Oxidizer is used to limit production of oxides of Nitrogen (Nox) and oxides of Sulphur (Sox) in the emissions. Flame based oxidizers produce Nox and Sox. The electric oxidizer, which has no flame-based heat source, maintains operational temperature below the auto formation temperature of Nox and Sox. In a PFAS/Hydrocarbon co-contaminant situation or during a macro Total Oxidizable Precursor Assay, the Blower (2) and Heater (3) assemblies will operate at lower temperatures to remove the hydrocarbons or cleave hydrocarbons from unsaturated Polyfluoroalkyls before PFAS is released from the soil or sludge. If the concentration of hydrocarbon exceeds a certain pre-set concentration, which could cause the catalyst to over-heat, the Electric Catalytic Oxidizer will activate the Catalytic Oxidizer Dilution Valve (42) to open to cool the catalyst. In turn the Blower (2) and Heater (3) assemblies mounted on the Polarity Conversion Unit (1) will reduce flows and temperature to accommodate catalyst cooling.
[0246] When hydrocarbons and/or cleaved hydrocarbons have been removed from the media under treatment, the Blower (2) and Heater (3) assemblies will increase treatment gas temperature and the Catalytic Oxidizer Bypass Damper (9) will be closed causing the treatment gas to bypass the Electric Catalytic Oxidizer (10).
[0247] Hot treatment gases enter the Cooling Chase (11) for cooling. The Cooling Chase Cooling Fluid Line (12) delivers cooling fluid through high pressure water jets and misting nozzles mounted in the Cooling Chase (11) and the Mist Chamber (13). Cooling fluids are directly sprayed into the treatment gas for cooling. The fine droplet size and the pressurized delivery cause an evaporative environment to exist within the Cooling Chase (11) and the Mist Chamber (13), which in turn dramatically and rapidly reduces temperature of the treatment gas. In order to prevent water from condensing out of the treatment gas, the cooling fluid is maintained above ambient outdoor temperature. The cooled treatment gas enters the Vapor Conversation Tank (14) where the gas encounters the Gibbs Energy Curtain (not shown in
[0248] The First Vapor Extraction Blower (in series) (20) applies vacuum pressure and provides treatment gas conveyance for the entire apparatus. The First Vapor Extraction Blower (in series) (20) bearing assembly is cooled with water stored in the Bearing Cooling Water Tank (First Blower) (21). The bearing cooling system allows for a higher tolerance in temperature of the treatment gas.
[0249] Treatment gas is then routed into the Vapor Phase Galvanic Separator (22) where residual PFAS that escaped the Vapor Conversation Tank (14) encounter a galvanic sequence of granulated metal that offer high surface area, high energy interfaces of varying charges for amphiphilic self-assembly. The resulting voltage can be galvanic or impressed generated currents. Voltage drops across the galvanic cell indicate active self-assembly and provide an indication of PFAS mass within the filter media. The galvanic filter media can be recharged by placing the filter assembly in the Polarity Conversion Unit (1). Traditional Vapor Phase Granular Activated Carbon Vessels (2 in series) (23) are used as a final emission polishing treatment.
[0250] The Vapor Phase Galvanic Separator (22) and the Vapor Phase Granular Activated Carbon Vessels (2 in series) (23) are maintained under vacuum pressure by a Second Vapor Extraction Blower (in series) (24) to prevent any leakage during treatment. The Second Vapor Extraction Blower (in series) (24) bearing assembly is cooled with water stored in the Bearing Cooling Water Tank (Second Blower) (25). The Second Vapor Extraction Blower (in series) (24) discharges the treated clean treatment gas to the Vent Stack (26) and through the Vent Stack Weather Cover (27) to the atmosphere at elevation.
[0251] The Fluids Line Assembly is connected to the Vapor Line Assembly through the Brine Pot Evaporator Connection Valve (47), which connects to the Vapor Extraction Manifold (7). System vacuum is used to contain, treat and convey PFAS saturated fluids and foams while providing a means for vapor phase treatment. The Brine Pot Vapor Extraction Line (28) draws PFAS vapors from the Brine Pot Evaporator (29). Vapors exit the Brine Pot Evaporator (29) through the Brine Pot Demister Tower (30), which is designed to remove any mists from the vapor stream before entry into the vapor line assembly. The Brine Pot Evaporator (29) is equipped with a Blower (31) and Heater (32) that provide hot air into the vessel to facilitate drying of PFAS fluids concentrate in an isolated batch process.
[0252] The Brine Pot Evaporator (29) has isolated two lines connected to downstream implements. The first line is the Vapor/Foam/Fluids Extraction Line (33) that provides vacuum pressure to the Surface Excess Concentrator (37) and a means of conveyance for separated foam/fluid PFAS concentrate. The second line is the Amphiphilic Decontamination Wand Flexible Extraction Line (34), which provides vacuum pressure and treatment gas conveyance for the Amphiphilic Decontamination Wand (35). The Amphiphilic Decontamination Wand (35) is used to decontaminate hard surfaces such as metal, concrete or other similar hard surfaces where amphiphilic PFAS self-assembly occurs. The Brine Pot Evaporator (29) creates a pressure drop in the vapor stream flow causing foams/fluids to drop out of the vapor stream where all emissions are routed to the vapor line assembly for emissions treatment. Accumulated foams/fluids are subsequently dried into a powder in the Brine Pot Evaporator (29) in a batch process. The Powder Vacuum Assembly (41) is used to remove dried PFAS powder from the Brine Pot Evaporator (29). The Powder Vacuum Assembly (41) is connected to the Vapor Extraction Line to Emissions Treatment (46). System vacuum provides vacuum and powder conveyance into a disposal drum or vessel; the pressure drop in the drum allows for powder accumulation.
[0253] The fluids treatment of this invention begins with the First Fluids Pump (in series) (36) where raw untreated fluids such as landfill leachate or sewer plant waste water is drawn into the apparatus. The First Fluids Pump (in series) (36) discharges fluids into the Surface Excess Concentrator (37). Amphiphilic PFAS are attracted to high energy interfaces such as the air/water interface or an air/fluid interface. The accumulation of amphiphilic compounds at the interface is termed Surface Excess. Once an interface area has been covered by an amphiphilic monolayer, amphiphilic micelles and monomers form within the bulk of the fluids. When the surface excess is removed, micelles and monomers in the bulk will self-assemble at the newly exposed interface. The Surface Excess Concentrator (37) takes advantage of the reliable self-assembly of amphiphilic PFAS compounds as a primary removal technique. System vacuum applied to the Surface Excess Concentrator (37) through the Vapor/Foam/Fluids Extraction Line (33) draws outside air into the Surface Excess Concentrator Purge Lines (38) and through the fluids, which in turn causes foam formation, a saturated PFAS amphiphilic layer at the foam/fluid interface and a PFAS micelle layer just below the surface. The foam and the saturated PFAS amphiphilic layers are removed by the Foam Belt (43) for subsequent treatment. The Foam Belt (87) is designed to have specific polar and dispersive surface energies to match or nearly match PFAS amphiphilic mixtures for maximum adhesion to the belt. The belt speed is modulated to recover the foam and the upper layer of the fluids for removal of the entire surface excess column around the interface. Residual PFAS monomers are treated downstream of the Surface Excess Concentrator (37) The final treatment for the fluids line is the Aqueous Phase Galvanic Separator (2 in series) (39); two vessels are assembled in series. The Aqueous Phase Galvanic Separator presents a galvanic sequence of granulated metal that offer high surface area, high energy interfaces of varying charges for amphiphilic self-assembly. Voltage drops across the galvanic cell indicate active self-assembly and provide an indication of PFAS mass within the filter media. The galvanic filter media can be recharged by placing the filter assembly in the Polarity Conversion Unit (1). The Second Fluids Pump (in series) (40) provide enough suction to the fluids to overcome the applied vacuum in the Surface Excess Concentrator (37). The Second Fluids Pump (in series) (40) discharges clean treated fluids to an appropriate discharge point.

[0256] The Vapor Extraction Manifold (7) provides isolated Individual Extraction Lines (5) a connection to the Vapor Extraction Line to Emissions Treatment (46). In addition, the Vapor Extraction Manifold (7) provides a connection for the Brine Pot Evaporator (29) through the Brine Pot Evaporator Connection Valve (47).

[0264] In order to regulate cooling fluids temperature and maintain temperatures above ambient outdoor temperature, outside air is drawn through Purge Lines (16), which are vented at the top of the Vapor Conversion Tank (14) and equipped with a control valve that regulates outside air intake. The Purge Lines (16) are slotted at the bottom of the Vapor Conversion Tank (14). System vacuum causes outside air to enter the Purge Lines (16) and create bubbles in the cooling fluid. The Bubbles cool the cooling fluid, cause fluid mixing, and maintains temperature above ambient outside temperature. Maintaining temperatures above ambient outside temperature in the Vapor Conversion Tank (14) combined with cooling fluid droplet size prevent water condensation within the tank.
[0265] Treatment gas exit the Cooling Chase (11) and the Mist Chamber (13) and encounter the Vapor Conversion Tank Gibbs Energy Curtain (66). The Gibbs Energy Curtain (66) consists of Gibbs Energy Curtain Tabs (70) and Gibbs Energy Curtain Air Gaps (71). The Tabs (70) consist of materials with specific polar and dispersive Gibbs surface energy profile to match or closely match contaminants that facilitate condensation on to the tabs (70). Treatment gas flows through the device where the rapid cooling and physiochemical processes cause the tabs (70) to be coated with contaminant. The Gibbs Energy Curtain (66) is removeable through the Gibbs Energy Curtain Access (15).
[0266] Treatment gas flows through the Gibbs Energy Curtain (66), then downward under the Vapor Conversion Tank Vapor Diversion Baffle (67); as seen in
[0267] The Vapor Conversion Tank (14) has various sampling, viewing and access ports including the Vapor Conversion Tank View Window (63) and Vapor Conversion Tank Access Hatch (65) as seen in
[0268] The vast majority of PFAS is removed from the treatment gas in the Vapor Conversion Tank (14). Amphiphilic PFAS compounds almost always have monomers that escape primary treatment mainly due to the weak Van Der Waals bonds. The Vapor Phase Galvanic Separator (22) is designed to remove residual monomer PFAS where a galvanic sequence (galvanic or impressed currents) of granulated metal that offer high surface area, high energy interfaces of varying charges for amphiphilic self-assembly. Voltage drops across the galvanic cell indicate active self-assembly and provide an indication of PFAS mass within the filter media. The galvanic filter media can be recharged by placing the filter assembly in the Polarity Conversion Unit (1).

[0272] The level of brine and foam inside the Brine Pot Evaporator (29) is monitored through the Brine Pot Fluid Level Window (79). In the event foam does not quickly decay inside the Brine Pot Evaporator (29), the Brine Pot Water Spray Foam Knock Down Assembly (80) will direct a blast of high-pressure water spray using the Brine Pot Water Spray Foam Knock Down Spray Nozzle (83) to knock down foam levels in the tank.
[0273] The Fluids Treatment Assembly line consists of two primary treatments in series where the initial treatment removes the majority of PFAS contaminants followed by a polishing treatment removing lower concentration monomeric PFAS as seen in
[0274] The raw PFAS contaminated fluids enter into the Surface Excess Concentrator Fluids Process Tank (88) where Surface Excess Concentrator Purge Lines (38) are vented to outside air. The vacuum applied the Surface Excess Concentrator Foam Tank (89) draws outside air through the Purge Lines (38), which are slotted at the bottom of the Process Tank (88). The Outside air creates bubbles in the raw fluids where foam is created at the surface, which is the same elevation as the inlet (85) and outlet (86). Long chain PFAS concentrate in the foam allows shorter chain PFAS to accumulate at the foam/fluid interface and PFAS micelles just below the fluid/foam interface. The fluid surface offers a high energy interface for self-assembly. PFAS mixtures create the foam framework lifting long chain compounds from the fluid surface. The Surface Excess Concentrator Foam Belt (87) removes the entire concentrated surface excess complex from the Process Tank (88) and delivers it to the Foam Tank (89) where the foam/fluid mixture is drawn into the Extraction Line (33) and subsequently delivered to the Brine Pot Evaporator (29). Treated fluids exit the Fluids Process Tank (88) through the Surface Excess Concentrator Fluids Exit Piping (bottom intake of Fluids Process Tank) (90). The Fluids Exit Piping Bottom Intake (92) is located the maximum distance below the surface excess formation occurring during treatment as seen in
[0275] The Foam Belt (87) uses a material that is designed to match or closely match the polar and dispersive energies associated with PFAS compounds and associated mixtures. Perfect wetting and adhesion occur when the fluids energy and solid surface energy polar and dispersive ratios match or closely match. The speed of the Foam Belt (87) rotation also causes the entire surface excess complex to be conveyed to the Foam Tank (89). The Surface Excess Concentrator Access Hatch (91) provides a means to change the Foam Belt (87) and to perform other maintenance tasks.
[0276] The second Fluids Treatment apparatus is intended to treat residual monomeric PFAS that passed through the Surface Excess Concentrator (37). The Aqueous Phase Galvanic Separator (39) is deployed, two in series, as seen in
