  • Patent number: 10525419
    Abstract: An oil-water separation membrane is described. The oil-water separation membrane comprises a porous metal sheet with a photocatalyst layer on one side and a layer of nanoparticles and a surfactant on the other side. The layer of nanoparticles and surfactant create a superoleophobic and superhydrophilic coating that allows passage of an aqueous phase and rejection of an oil phase. The photocatalyst layer, combined with UV irradiation, enables degradation of organic contaminants in the aqueous phase. The oil-water separation membrane may be used as part of an oil-water separation system, and a filtered water product may be recycled through the membrane to increase the removal of organic contaminants.

  • Patent number: 8747669
    Abstract: A separation module and method are disclosed for processing a liquid sample and providing high conversion by operating a single-pass tangential-flow process without a recirculation loop. In one embodiment, the separation module includes three reservoirs and has at least one long, thin channel with a large ratio of channel membrane area to: channel void volume; volume of a sample feed reservoir; and volume of the feed sample. In another embodiment, the separation module includes an external feed reservoir, an external retentate reservoir fluidly and a first vacuum source adapted to apply a first vacuum to the separation element disposed within the housing. The single-pass TFF separation element and single-pass process provides high conversion while operating with relatively low pressure sources. Certain embodiments disclosed herein can be used for the separation of blood.
