Publication number: 20120175305Abstract: Gas-filled microbubbles can be synthesized using a continuous flow chamber and a sonicator. The resulting microbubble solution can be size-sorted for a particular application, such as injection into a patient for gas delivery thereto. The microbubble solution may be concentrated to have greater than 50% volume gas while maintaining microbubble sizes below 10 ?m. Control of the microbubble generation process can yield highly stable microbubbles. The microbubbles may retain over half of their original gas payload for over three weeks while exhibiting minimal change in microbubble size. The systems, methods, and devices described herein thus allow for continuous or batch-wise continuous production of gas-filled microbubbles that readily release their gas payload when introduced into an under-saturated or de-saturated solution.Type: ApplicationFiled: August 26, 2010Publication date: July 12, 2012Applicant: The Trustees of Columbia University in the City of New YorkInventors: Mark A.

Publication number: 20120152761Abstract: Wastewater containing soluble selenium is treated in a bioreactor. Microorganisms in the reactor reduce the selenium to elemental selenium, which is insoluble. The elemental selenium is discharged from the reactor in waste sludge. The sludge is treated to recover selenium. In one method, the sludge is washed with chemicals, for example surfactants, and agitated to disrupt the adhesion of the selenium particles to the cells. The selenium particles are then separated from the cells using a physical separation process such as a centrifuge or differential filtration. In another method, the sludge is de-watered or dried to a very high solids content. The selenium particles are dissolved using an oxidizer under high pH conditions. A solids fraction is removed from the resulting slurry. A resulting selenium brine is further refined to recover the selenium.Type: ApplicationFiled: December 17, 2010Publication date: June 21, 2012Inventors: Timothy Michael Pickett, Jill Noreen Sonstegard

Patent number: 8025801Abstract: Simultaneous source-sink flow, or radial counterflow, is driven by a centrifugal pump disposed within a casing. Radially outward source flow of brine goes into a shrouding tank and concentrates while a radially inward sink flow of fresh water flows back over the pump to axial extraction. An axial pump drives sink flow and axial extraction. Convergent sink flow passes under an inductor to an axial exhaust port. Induced viscosity and inductive repulsion hinder the passage of brine in sink flow, so only fresh water can reach the axial exhaust port. Crystallization of scale-forming salts is aided by Joule heating from the inductor. Solvent and gases are continuously axially extracted in sink flow, favoring crystallization. Sodium chloride is cooled and crystallized in the shrouding tank. Brine comprising other salts flows out of the tank to treatment by suitable means. Thus brine is separated into fresh water, crystallized salt, and concentrated brine.Type: GrantFiled: August 16, 2007Date of Patent: September 27, 2011Assignee: McCutchen Co.Inventor: Wilmot H.

Patent number: 8012354Abstract: A process for purifying a lipid composition having predominantly neutral lipid components having at least one long chain polyunsaturated fatty acid is disclosed. The process employs contacting the lipid composition with a polar solvent, such as acetone, wherein the solvent is selected such that contaminants are less soluble in the solvent than is the long chain polyunsaturated fatty acid. The process is typically conducted at cooler temperatures, including about 0° C. Upon precipitation of the contaminants from the lipid composition, a separation is conducted to remove the precipitated material from the lipid composition. The long chain polyunsaturated fatty acids can include ARA, DPA, EPA, and/or DHA. The process of the present invention effectively winterizes lipid compositions, thereby reducing the tendency of such compositions to become hazy.Type: GrantFiled: April 9, 2010Date of Patent: September 6, 2011Assignee: Martek Biosciences CorporationInventors: Daniel G.

Publication number: 20110152740Abstract: A method and apparatus for red blood collection and filtration is provided wherein a red blood cell collection assembly provides for leukoreduction filtration concurrent with or soon after the red blood cell separation and collection procedure. After red blood cells have been collected, an unwanted blood component, e.g., buffy coat, is diverted into the red blood cell collect line. Operation of a peristaltic pump engaging pump loop allows insertion of a pre-determined quantity of buffy coat into the collect line. The buffy coat can therefore push red blood cells out of the filter and into a collect bag without diluting the collected red blood cells. Alternatively, gravitational force may be used to allow the unwanted blood component to displace red blood cells out of the filter.Type: ApplicationFiled: December 8, 2010Publication date: June 23, 2011Applicant: CARIDIANBCT, INC.Inventor: Bruce W.

Publication number: 20110120959Abstract: A variety of improved hydroclone based fluid filtering systems are described. The hydroclones generally include a tank having an internal chamber and a filter (preferably a surface filter) that is positioned within the internal chamber. The filter defines a filtered fluid chamber within the internal chamber of the tank. The hydroclone may be operated such that a vortex of flowing fluid is formed between the chamber wall and the filter with the filter being located in the center of the vortex. With this arrangement, the filter acts as a cross-flow filter. In one aspect of the invention, the filter is a stepped filter. In another aspect of the invention, the filter is an surface filter, as for example, an electroformed metal surface filter. In some preferred embodiments, the openings in the filter are arranged as slots that extend substantially vertically so that they are oriented substantially perpendicular to the flow path of fluid flowing in the adjacent portion of the vortex.Type: ApplicationFiled: February 1, 2011Publication date: May 26, 2011Applicant: CLEAN FILTRATION TECHNOLOGIES, INC.Inventors: David J.
