  • Patent number: 10544445
    Abstract: A rapid one-pass liquid filtration system efficiently concentrates biological particles that are suspended in liquid from a dilute feed suspension. A sample concentrate or retentate suspension is retained while eliminating the separated fluid in a separate flow stream. Suspended biological particles include such materials as proteins/toxins, viruses, DNA, and/or bacteria in the size range of approximately 0.001 micron to 20 microns diameter. Concentration of these particles is advantageous for detection of target particles in a dilute suspension, because concentrating them into a small volume makes them easier to detect. Additional concentration stages may be added in “cascade” fashion, in order to concentrate particles below the size cut of each preceding stage remaining in the separated fluid in a concentrated sample suspension. This process can also be used to create a “band-pass” concentration for concentration of a particular target size particle within a narrow range.

    Abstract: Disclosed are system and method for filtration which can minimize the contamination of the filtering membrane through a pretreatment and perform the pretreatment and the filtration with a filtering membrane in a single filtering unit so that any need for separate and additional space and facility for the pretreatment can be obviated. The system for filtration of the present invention comprises a fine bubble supplier for providing fine bubbles into the feed water. The pretreatment is performed by supplying the feed water to be treated into the filtering unit through a dynamic filtration layer which is formed in the filtering unit as the fine bubbles rise.

  • Patent number: 9987377
    Abstract: A method of targeting bacterially-derived, intact minicells to specific, non-phagocytic mammalian cells employs bispecific ligands to deliver nucleic acids efficiently to the mammalian cells. Bispecific ligands, comprising (i) a first arm that carries specificity for a bacterially-derived minicell surface structure and (ii) a second arm that carries specificity for a non-phagocytic mammalian cell surface receptor are useful for targeting minicells to specific, non-phagocytic mammalian cells and causing endocytosis of minicells by non-phagocytic cells.

  • Patent number: 9950103
    Abstract: A combination kidney and liver dialysis system and method provides a portable, lightweight hemodialysis device that removes uremic toxins, hepatic toxins, water, and impurities from the blood. The method comprises separating the blood into a plasma portion and a cellular portion, immediately returning the cellular portion to the body, providing large volumes of replacement fluids, diluting the plasma portion with replacement fluids, and then manipulating the plasma portion of the blood to pass through hemoperfusion membranes, hemodiafiltration membranes, and extracorporeal membrane oxygenation membranes. Dialysis is performed on the plasma portion of the blood with an albumin dialyzer against an albumin dialysate and a high molecular weight cut off membrane. Dialysis is performed on the plasma portion of blood with a lipid dialysate comprising 10-30% lipid composition, and a high flux dialyzer.

  • Patent number: 9833744
    Abstract: Provided are processes of removing particulate fouling from a filtration membrane or for preventing membrane fouling by particulate matter. A process capitalizes on reversal of a naturally occurring diisophoretic particle deposition to actively move particulate material away from a membrane. A process includes placing a microparticle including a salt in proximity to a membrane such that the microparticle creates a gradient generated spontaneous electric field or a gradient generated spontaneous chemiphoretic field in the solvent proximal to the membrane that actively draws charged particles away from the membrane thereby removing charged particulate matter away from the membrane or preventing its deposition.

  • Patent number: 9758393
    Abstract: Provided is a fresh water generation system which filters biotreated water produced by microbiologically treating waste water via a primary semi-permeable membrane (8), and then mixes concentrated water rejected by the filtration with seawater, thereby to filter the mixed water via a secondary semi-permeable membrane (14). This system enables frequencies of chemical cleaning and replacement of the secondary semi-permeable membrane to be reduced. The fresh water generation system comprises: a primary semi-permeable membrane apparatus (9) which separates microorganism treating waste water into permeated water and concentrated water; a secondary semi-permeable membrane apparatus (13) which filters mixed water prepared by mixing the concentrated water into seawater. In the fresh water generation system, the primary semi-permeable membrane (8) has an equal to or a higher microorganism adhesive property than the secondary semi-permeable membrane (14).
