A liquid-dissolved gas separator includes a metallic separator. The separator has a plurality of open pores that connect a liquid-facing surface of the separator with an opposed vacuum-facing surface of the separator for separating dissolved gases from a liquid traversing the liquid-facing surface of the separator body.

A hydrogen separation membrane employs a dense liquid metal separator deposited on a support structure for providing a membrane film allowing passage of hydrogen to be used in industrial processes and consumer applications benefiting from pure hydrogen. A support structure such as silicon carbide is non-reactive with the molten metal, thus withstanding the high temperatures associated with hydrogen producing processes. The liquid metal wets, or adheres/covers the support structure to form a continuous membrane for passing only hydrogen and resisting breakdown leading to discontinuity in the membrane surface. The molten (liquid) metal membrane is sandwiched between porous and inert ceramic supports to form a continuous thin film. Molecular hydrogen dissociates on the liquid metal membrane surface when exposed to a hydrogen gas mixture. The resulting hydrogen atoms dissolve into and diffuse across liquid metal film to arrive at the opposite surface, where they reassociate and desorb as pure hydrogen gas.

A novel fluid filtration system that exhibits antifouling properties against a variety of potential foulants includes at least one filtration membrane placed in a cross-flow filtration module. The module is subjected to microwave irradiation at a certain power or intensity over a controlled time interval. At least one microwave generator produces microwaves and may be fixed or movable to treat the fluid. Dislodged foulants are removed by the microwave electromagnetic energy from the filtration membrane and carried away in a cross-flow stream and wasted or recycled back to a feed solution container. The filtration system may use different filtration configurations such as, but not limited to, flat sheet, hollow fiber, spiral wound and tubular membranes. The filtration membrane materials may be polymeric, ceramic, and combinations. The functionalized membranes can be such as, but not limited to, membranes coated or blended or cross-linked with materials displaying strong microwave absorption; and combinations.
