Patent ID: 10583402

Abstract:
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.
