Abstract
The present disclosure relates to systems and methods for electrically conductive membrane separation from a mixture solution via membrane nanofiltration, electro-filtration, or electro-extraction by: generating an electric field at the membrane filter, holding the membrane filter at a constant electric potential, or driving a constant current through the membrane filter; feeding a mixture solution through the membrane nanofiltration system; and separating a component from the mixture solution into a permeate solution.
Claims30
A membrane nanofiltration system for electrically conductive membrane separation comprising:
- a membrane filter comprising a nanoporous structure;
- an electrical contact in contact with the membrane filter;
- and
- a counter electrode above a top surface of the membrane electrode,
- wherein the membrane filter, via the electrical contact, and the counter electrode are configured to generate an electric field between the membrane filter and the counter electrode, to hold the membrane filter at a constant electric potential, or to flow constant current into the membrane filter, and
- wherein the membrane filter is configured to separate a component from a mixture solution into a permeate solution.
