Patent number: 8119000Abstract: A combined degassing and flotation tank for separation of a water influent containing considerable amounts of oil and gas. A rotational flow is created in the tank which forces the lighter components such as oil and gas droplets towards an inner concentric cylindrical wall where they coalesce and rise to the surface of the liquid and are removed via the outlet. The heavier parts are forced down where the heavy particles sink to the lower part where they can be removed as a sludge. The water is discharged via an outlet in the lower part of the tank. The combined degassing and flotation tank is particular suited for use in oil production at sea for removal of oil and gases from water streams before the water is returned to the sea.Type: GrantFiled: May 7, 2009Date of Patent: February 21, 2012Assignee: Schlumberger Norge ASInventor: Stein Egil Oserød

The ball is configured to lift between the lower face and the upper face in response to an air pressure differential acting on the ball. This opens the valve to purge air trapped in the housing. The ball is further configured to close the valve by sealing against the valve outlet in the upper face in response to a pressure differential across the ball created by unfiltered fuel entering the valve.Type: GrantFiled: February 17, 2009Date of Patent: May 10, 2011Assignee: Parker Hannifin (UK) LimitedInventors: Phil Core, James Ashton, Steven Wilson

Publication number: 20110100924Abstract: A compact and portable liquid concentrator and contaminant scrubber includes a gas inlet, a gas exit and a flow corridor connecting the gas inlet and the gas exit, wherein the flow corridor includes a narrowed portion that accelerates the gas through the flow corridor. A liquid inlet injects liquid into the gas stream at a point prior to the narrowed portion so that the gas-liquid mixture is thoroughly mixed within the flow corridor, causing a portion of the liquid to be evaporated. A demister or fluid scrubber downstream of the narrowed portion removes entrained liquid droplets from the gas stream and re-circulates the removed liquid to the liquid inlet through a re-circulating circuit. A reagent may be mixed with the liquid to react with contaminants in the liquid.Type: ApplicationFiled: November 3, 2010Publication date: May 5, 2011Applicant: HEARTLAND TECHNOLOGY PARTNERS LLCInventors: Bernard F.

Publication number: 20110100911Abstract: In a sewage treatment system, microconstituents, including personal care products and pharmaceutical materials, often difficult to degrade biologically, are removed by supersaturating the untreated wastewater feed with ozone. This breaks down refractory microconstituents into more readily biodegradable materials, subsequently treated preferably in an activated sludge membrane bioreactor process. The oxygen biproduct of ozonation is utilized by feeding the oxygen into an aerobic part of the plant to meet a portion of the biological demand, thereby increasing efficiency of ozone use in the process.Type: ApplicationFiled: November 2, 2009Publication date: May 5, 2011Inventor: Dennis Livingston

Publication number: 20110100932Abstract: A method for handling separation media slurry in a tank, before transferring the separation media slurry to a column or a container. The method comprises the steps of: —blowing gas from the bottom of the tank into the sedimented media in the tank and thereby the sedimented media starts to re-suspend; —starting an impeller (7) provided in the tank in order to stir said media slurry that already has started to re-suspend.Type: ApplicationFiled: June 4, 2009Publication date: May 5, 2011Applicant: GE HEALTHCARE BIO-SCIENCE ABInventors: Tom Lonnqvist, Roger Nordberg, Joakim Lundkvist

Publication number: 20110092875Abstract: A device for degassing gas bubbles out of a liquid comprises a housing having a liquid inlet, a liquid outlet and a gas bubble outlet. The housing includes a spiral wall defining a spiral flow path for the liquid and a hydrophobic membrane above the spiral wall and between the spiral wall and the gas bubble outlet. The spiral wall forces inward liquid entering the housing through the inlet into a spiral flow along the spiral flow path, and causes an upward flow of the gas bubbles toward the hydrophobic membrane. A method for degassing gas bubbles out of a liquid, e.g., blood, e.g., during hemodialysis, hemofiltration and hemodiafiltration, and use of such a degassing device in an extracorporeal circuit for degassing gas bubbles out of liquid, e.g., blood, e.g., during hemodialysis, hemofiltration and hemodiafiltration, are disclosed.Type: ApplicationFiled: April 28, 2009Publication date: April 21, 2011Applicant: GAMBRO LUNDIA ABInventor: Christof Beck

Patent number: 7922897Abstract: A fluidized bed reactor for removing phosphorus and nitrogen from wastewater has a column comprising a number of sections. The diameter of the column changes stepwise between the sections. A flow velocity in excess of 100 cm/min is maintained in a lowermost one of the sections and lower flow velocities are maintained in subsequent sections. A struvite supersaturation ratio is controlled in part by recycling wastewater from an outlet of the column. Struvite pellets are removed periodically from the bottom of the column.Type: GrantFiled: October 13, 2009Date of Patent: April 12, 2011Assignee: The University of British ColumbiaInventors: Fred A.
