Abstract
A method and apparatus for treating dilute and micro concentrations of pollutants, particularly PFASs, in aqueous solutions. The apparatus including an electrode assembly including a working electrode, a counter electrode, and a cell divider positioned between the working electrode and counter electrode. The cell divider including an ion conducting membrane where the ion conducting membrane selectively conducts protons or hydroxyl anions but is an electronic insulator and a barrier to liquid, contaminant, and gas exchange.
Claims25
An electrode assembly comprising
- a working electrode,
- a counter electrode, and
- a cell divider positioned between the working electrode and counter electrode;
- wherein said cell divider comprises an ion conducting membrane
- wherein said ion conducting membrane selectively conducts protons or hydroxyl anions but is an electronic insulator and a barrier to liquid, contaminant, and gas exchange.
The contaminated solution treatment process additionally comprising:
- recirculating an electrolyte solution through one or more counter electrode compartments, wherein the electrolyte solution is directed through the counter electrode compartment(s) and passes through a liquid-gas separator after exiting the compartment which removes the counter electrode gases
- separating product gas from the electrolyte solution,
- wherein the electrolyte solution has a hardness of below 60 mg/L and a conductivity above 500 μS/cm, and a pH of 6 or less.
