Electrically conductive membrane assembly and related systems and methods

A membrane assembly for separating a feed liquid into a permeate and a retentate, the membrane assembly comprising:

• a first side for receiving the feed liquid;
• a second side for outputting the permeate;
• a membrane body comprising a semipermeable front surface at the first side, a back surface at the second side, and a thickness defined from the semipermeable front surface to the back surface,
• wherein the membrane body is configured to pass the permeate through the semipermeable front surface to the back surface, and prevent the retentate from passing through the semipermeable front surface;
• a porous first electrically conductive member positioned at the first side and configured to pass the feed liquid through the porous first electrically conductive member to the semipermeable front surface;
• a porous second electrically conductive member positioned at the second side and configured to pass the permeate from the back surface through the porous second electrically conductive member,
• wherein the porous first electrically conductive member and the porous second electrically conductive member are configured to maintain the semipermeable front surface in an electrically charged state when a voltage is applied between the porous first electrically conductive member and the porous second electrically conductive member;
• and
• a wireless power receiving unit configured to wirelessly receive electrical power from a wireless power transmitting unit external to the membrane assembly in electrical communication, wherein the wireless power receiving unit is in electrical communication with at least one of the porous first electrically conductive member or the porous second electrically conductive member for transmitting the received electrical power to the at least one of the porous first electrically conductive member or the porous second electrically conductive member.
