Abstract
A method of treating contaminated water includes contacting the contaminated water including a fluoroalkyl compound with a galvanic cell to form galvanic cell-treated water including a galvanic cell-treated fluoroalkyl compound. The method also includes separating the galvanic cell-treated fluoroalkyl compound from the galvanic cell-treated water to form product water having a lower concentration of the fluoroalkyl compound than the contaminated water and to form an aqueous concentrate having a higher concentration of the galvanic cell-treated fluoroalkyl compound than the product water.
Claims20
A method of treating contaminated water, the method comprising:
- contacting the contaminated water comprising a fluoroalkyl compound with a galvanic cell to form galvanic cell-treated water comprising a galvanic cell-treated fluoroalkyl compound;
- adding a metal component comprising a metal to the contaminated water prior to or during the contacting of the contaminated water and the galvanic cell, wherein the metal component is a ion of the metal, a solid or dissolved compound of the metal, an elemental form of the metal, or a combination thereof, wherein the metal of the metal component is the same as a metal in one or more electrodes of the galvanic cell;
- separating the galvanic cell-treated fluoroalkyl compound from the galvanic cell-treated water to form product water having a lower concentration of the fluoroalkyl compound than the contaminated water and to form an aqueous concentrate comprising the metal component and having a higher concentration of the galvanic cell-treated fluoroalkyl compound than the product water;
- and
- reusing the metal component in the aqueous concentrate as the metal component that is added to the contaminated water.
A method of treating contaminated water, the method comprising:
- contacting the contaminated water comprising a fluoroalkyl compound with a galvanic cell to form galvanic cell-treated water comprising a galvanic cell-treated fluoroalkyl compound;
- separating the galvanic cell-treated fluoroalkyl compound from the galvanic cell-treated water to form product water having a lower concentration of the fluoroalkyl compound than the contaminated water and to form an aqueous concentrate comprising a metal component and having a higher concentration of the galvanic cell-treated fluoroalkyl compound than the product water, wherein the metal component is a ion of the metal, a solid or dissolved compound of the metal, an elemental form of the metal, or a combination thereof, and wherein the metal of the metal component is the same as a metal in one or more electrodes of the galvanic cell and the metal component is produced during the contacting of the contaminated water and the galvanic cell;
- and
- adding the metal component to the contaminated water prior to or during a subsequent cycle of the contacting of the contaminated water and the galvanic cell.
