Abstract
A method of treating feed water includes adding a metal component to the feed water to form a clarified aqueous composition.
Claims (31)
1. A method of treating feed water, the method comprising:
adding a metal component comprising a metal that is aluminum to the feed water, wherein the feed water comprises a fluoroalkyl compound that is a perfluoroalkyl or polyfluoroalkyl substance (PFAS), perfluoroalkyl substance, a polyfluoroalkyl substance, a perfluoroalkyl acid (PFAA), or a combination thereof, wherein the metal component comprises an ion of the metal, a solid or dissolved compound of the metal, an elemental form of the metal, or a combination thereof, wherein the addition of the metal component to the feed water forms a solid;
removing the solid from the metal component-treated feed water, to form a clarified aqueous composition and to form an aqueous concentrate having a higher concentration of the solid than the clarified aqueous composition, wherein the aqueous concentrate comprises the metal component added to the feed water, and wherein the clarified aqueous composition has a lower concentration of the fluoroalkyl compound as compared to the feed water; and
reusing at least some of the metal component in the aqueous concentrate as 1 wt % to 100 wt % of the metal component that is added to the feed water.
2. The method of claim 1 , wherein the metal component comprises an Al ion and/or aluminum hydroxide.
3. The method of claim 1 , wherein adding the metal component to the feed water comprises adding to the feed water a salt of the metal of the metal component.
4. The method of claim 1 , wherein the metal of the metal component is produced by a galvanic or electrolytic cell, wherein the addition of the metal component to the feed water occurs externally to the galvanic or electrolytic cell.
5. The method of claim 1 , further comprising acidifying the aqueous concentrate to bring a pH of the aqueous concentrate to a pH of 0.5 to 5 sufficient to at least partially dissolve one or more salts comprising the metal of the metal component added to the feed water, and reusing at least some of the metal of the metal component in the acidified aqueous concentrate as 1 wt % to 100 wt % of the metal component that is added to the feed water.
6. The method of claim 5 , further comprising purging one or more acidification contaminants from the acidified aqueous concentrate.
7. The method of claim 5 , wherein the contacting of the feed water and the metal component forms a metal component-treated fluoroalkyl compound, further comprising performing a secondary separation to separate a residual solution from the aqueous concentrate after the acidifying to concentrate the metal component-treated fluoroalkyl compound in the aqueous concentrate and to form the residual solution separated therefrom.
8. The method of claim 7 , wherein a ratio of a volume of the aqueous concentrate having the residual solution removed therefrom to a volume of the acidified aqueous concentrate prior to removal of the residual solution therefrom is 1:100,000 to 1:1.
9. The method of claim 5 , wherein the acidified aqueous concentrate comprises a metal component-treated fluoroalkyl compound formed by addition of the metal component to the feed water, wherein the method further comprises destroying the fluoroalkyl compound in the acidified aqueous concentrate, wherein destroying the fluoroalkyl compound comprises thermal treatment, treatment with an electrolytic cell, plasma reactor, supercritical water, combustion, chemical treatment, or a combination thereof.
10. The method of claim 1 , wherein the method is free of treating the feed water or clarified aqueous composition with a galvanic cell.
11. The method of claim 1 , further comprising treating the clarified aqueous composition with a galvanic cell, to form product water.
12. The method of claim 11 , wherein the galvanic cell comprises:
an anode comprising Al; and
a cathode having a different composition than the anode, wherein the cathode comprises Cu.
13. The method of claim 1 , further comprising purging one or more acidification contaminants from a recycle stream comprising the metal component from the aqueous concentrate prior to or during combining the recycle stream and the feed water.
14. A method of treating feed water, the method comprising:
performing a treatment comprising adding a metal component comprising aluminum to feed water comprising a fluoroalkyl compound to form a solid comprising a metal component-treated fluoroalkyl compound, wherein the metal component is an ion of the aluminum, a solid or dissolved compound of the aluminum, an elemental form of the aluminum, or a combination thereof;
removing the solid from the feed water to form a clarified aqueous composition having a lower concentration of the fluoroalkyl compound than the feed water and to form an aqueous concentrate having a higher concentration of the solid than the clarified aqueous composition;
acidifying the aqueous concentrate;
performing a secondary separation to separate a residual solution from the aqueous concentrate after the acidification and to concentrate the metal component-treated fluoroalkyl compound in the aqueous concentrate; and
adding the metal component from the residual solution to the feed water prior to or during the treatment.
15. A method of treating feed water, the method comprising:
performing a treatment comprising adding a metal component comprising aluminum to feed water comprising a fluoroalkyl compound to form a solid comprising a metal component-treated fluoroalkyl compound, wherein the metal component comprises an ion of the aluminum, a solid or dissolved compound of the aluminum, an elemental form of the aluminum, or a combination thereof;
removing the solid from the feed water to form a clarified aqueous composition having a lower concentration of the fluoroalkyl compound than the feed water and to form an aqueous concentrate having a higher concentration of the solid than the clarified aqueous composition;
acidifying the aqueous concentrate;
performing a secondary separation to separate a residual solution from the aqueous concentrate after the acidification and to concentrate the metal component-treated fluoroalkyl compound in the aqueous concentrate;
purging one or more acidification contaminants from the residual solution; and
adding the metal component from the residual solution to the feed water prior to or during the treatment.
