  • Crossflow filtration particle separator
    Patent number: 9827518
    Abstract: A form of crossflow filtration particle separator which receives a particle laden moving fluid surrounded by a clear moving fluid at a proximal end, and separates the particles into a collection zone, or collector, in response to vortices created by diagonal slits and baffles located from the center of the particle separator to its distal end. The filter operates horizontally in a small amount of space without use of physical filter media or the need of a high pressure flow, while allowing delicate particles to be separated without damage. Particle collection structures allow the separated particles to be carried away in a separate flow.
    Type: Grant
