Abstract: The present disclosure generally relates to the field of filtration. In particular, the present disclosure relates to filtration devices, systems and methods for high flowrates and low pressure differentials through porous bodies of metal fiber media.

Abstract: The present disclosure provides advantageous rotary interfaces for fluid assemblies (e.g., rotary interfaces for fluid flow in bioreactor applications), and related methods of fabrication and use. More particularly, the present disclosure provides improved rotary interfaces for fluid flow through porous impellers for filtration and/or sparging for fluid assemblies (e.g., bioreactor applications), and related methods of fabrication and use. Disclosed herein is a fluid assembly (e.g., bioreactor) that includes a porous impeller which is in fluid communication with a hollow shaft that can be used to transport a reaction fluid to an external storage tank or the like. The fluid assembly/bioreactor can include a coupling mechanism that transmits rotary motion from a motor to a primary shaft and then to a hollow secondary shaft, while at the same time permitting removal of a filtrate from the fluid assembly or bioreactor via the hollow secondary shaft and a porous impeller.

Abstract: Various embodiments are generally directed to techniques for splitting fluid flows with porous medium, such as a porous medium with metal particles, for instance. Some embodiments are particularly directed to a flow splitting assembly that creates a differential flow at a calibrated flow split. In one or more embodiments, for example, an apparatus for flow spitting may include a manifold comprising first, second and third manifold openings in fluid communication. In one or more such embodiments, introduction of a flow to the first manifold opening via an inlet filter may cause a differential flow at a calibrated flow split between a first restrictor coupled to the second opening of the manifold and a second restrictor coupled to the third opening of the manifold. In various embodiments, each restrictor may include one or more porous medium composed of metal particles.
