Fluorocarbon destruction method
A method of destroying a fluorocarbon compound includes regenerating an adsorbent to remove the fluorocarbon compound and to produce a regeneration fluid having a concentration of the fluorocarbon compound and directing the regeneration fluid to an electro-oxidation system. The method also includes applying a current to the electro-oxidation system to oxidize the fluorocarbon compound within the regeneration fluid and measuring a quantity of fluorides in the regeneration fluid to determine the progress of the removal of the fluorocarbon compound from the regeneration fluid.
1. A method of destroying a fluorocarbon compound, the method comprising:
regenerating an adsorbent to remove the fluorocarbon compound and to produce a regeneration fluid having a concentration of the fluorocarbon compound;
directing the regeneration fluid to an electro-oxidation system;
applying a current to the electro-oxidation system to oxidize the fluorocarbon compound within the regeneration fluid; and
measuring a quantity of fluorides in the regeneration fluid to determine the progress of the removal of the fluorocarbon compound from the regeneration fluid;
wherein the current has a current density of at least 5,000 A/m 2 .
2. The method of claim 1 , wherein the current density is at least 15,000 A/m 2 .
3. The method of claim 1 , further comprising measuring the total fluorocarbon input into the electro-oxidation system.
4. The method of claim 1 , wherein the adsorbent includes an ion-exchange resin.
5. The method of claim 1 , wherein the fluorocarbon compound includes per- and polyfluorinated alkyl substances (PFAS).
6. A method of destroying a fluorocarbon compound in a flow of water, the method composing:
directing the flow of water into a tank containing an adsorbent;
removing the fluorocarbon compound from the flow of water by facilitating the adsorption of the fluorocarbon compound with the adsorbent;
periodically regenerating the adsorbent to allow for re-use of the adsorbent, the process of regeneration comprising,
placing the adsorbent in a regeneration fluid, the fluorocarbon compound de-adsorbing from the adsorbent and collecting in the regeneration fluid;
directing the regeneration fluid to an electro-oxidation system;
applying a current to the electro-oxidation system to oxidize the fluorocarbon compound within the regeneration fluid; and
measuring a quantity of fluorides in the regeneration fluid to determine the progress of the removal of the fluorocarbon compound from the regeneration fluid;
wherein the current has a current density of at least 5,000 A/m 2 .
7. The method of claim 6 , wherein the current density is at least 15,000 A/m 2 .
8. The method of claim 6 , further comprising measuring the total fluorocarbon input into the electro-oxidation system.
9. The method of claim 6 , wherein the adsorbent includes an ion-exchange resin.
10. The method of claim 6 , wherein the fluorocarbon compound includes per- and polyfluorinated alkyl substances (PFAS).
