An optimal or peak time is observed for each peritoneal dialysis therapy outcome, such as ultrafiltrate volume rate, urea clearance (Kt/V), and creatinine clearance, while minimizing hydrocarbon absorption. These values and input parameters can be used to tailor the peritoneal dialysis dwell time for each patient, estimating the peak dwell time that will yield the best therapy outcome for each patient.Type: GrantFiled: April 28, 2009Date of Patent: May 24, 2016Assignees: Baxter International Inc., Baxter Healthcare S.A.Inventors: Ying-Cheng Lo, Alp Akonur, Isaac Martis

Patent number: 8980091Abstract: A method and system for controlling dissolved oxygen levels in a secondary treatment system of a wastewater treatment facility that can employ a membrane bioreactor in which oxygen introduction into mixed liquor is controlled to prevent bulking and minimize generation of extra cellular polymeric substances. The control is exercised by insuring that dissolved oxygen levels within the mixed liquor do not fall below a minimum system level at which microorganism stress would occur. This is done by setting a minimum dissolved oxygen level control point equal to a sum of the minimum system level and an adjustment factor determined on the basis of oxygen uptake rate and time delays inherent in sensing oxygen levels and changes thereof within the mixed liquor. The minimum system dissolved oxygen level can be continually calculated on the basis of an inferred food to mass ratio that would vary with sensed mixed liquor suspended solids.Type: GrantFiled: May 7, 2013Date of Patent: March 17, 2015Assignee: Praxair Technology, Inc.Inventor: Malcolm E.

Patent number: 8980092Abstract: A system and method includes an aeration subsystem that excites enzymes in the liquid waste passing through the septic system. The aeration subsystem includes a compressor section that compresses the liquid waste. The method includes mixing enzymes into the fluid waste material, compressing the fluid waste material with the compressor, injecting air into the compressed fluid waste material, and determining whether the fluid waste material is at a desired cleanliness, and if not, recirculating the fluid waste material through the compressor.Type: GrantFiled: December 10, 2013Date of Patent: March 17, 2015Inventors: Kenneth J. Kistner, Carolyn R. Kistner

Publication number: 20150068983Abstract: Disinfection device for installation into a water dispenser having an accumulating reservoir for drinking water filled from an external source of drinking water, including a flow-through ozone-air mixture generator provided with an air pump for external air delivery via an air filter to the ozone-air mixture generator. An output of the ozone-air mixture generator is connected with a delivery pipeline for delivery of ozone-air mixture or air inside the delivery pipeline. An electromechanical ultrasonic frequency irradiator is mounted on the delivery pipeline to generate ultrasonic oscillations in the pipeline walls and in water filling the pipeline, and a program control unit controls operation of the ozone-air mixture generator, air pump and electromechanical irradiator for disinfection and cleaning of inner surfaces of the pipeline and water therein. A method for the disinfection of water dispensers is also disclosed.Type: ApplicationFiled: April 9, 2013Publication date: March 12, 2015Applicant: SCANDINAVIAN INNOVATION GROUP OYInventor: Andrzej Pawlow

Patent number: 8968569Abstract: A method of wastewater reutilization by which reusable water can be stably obtained from a wastewater. Ozone is added to a wastewater, such as water resulting from sewage treatment, in such a small amount as to result in a residual ozone concentration as measured before membrane filtration of 0.01-1.0 mg/L. Ozone is thus brought into contact with fine solids contained in the wastewater to alter the surface properties of the fine solids so that the solids are easily to coagulate. Thereafter, a coagulant, e.g., PACl, is added from a coagulant addition device (3). The fine solids are coagulated in a coagulation tank (5) or a line mixer and the resultant water is subjected to membrane filtration with an ozone-resistant separation membrane (6) such as ceramic membrane. Thus, reusable water is obtained which has a residual ozone concentration, as measured after filtration through the membrane, less than 0.5 mg/L.Type: GrantFiled: December 24, 2008Date of Patent: March 3, 2015Assignee: Metawater Co., Ltd.Inventors: Shigehiro Suzuki, Motoharu Noguchi, Hideki Kozono

Patent number: 8968580Abstract: A pumpbox apparatus includes a reservoir volume having a first inlet for receiving a feedstock stream and a second inlet for receiving a water stream, the reservoir volume being in communication with a discharge outlet disposed to discharge accumulated liquid from the reservoir volume. The reservoir volume is operable to accumulate the feedstock stream and the water stream in the reservoir volume while withdrawing a discharge stream through the discharge outlet to cause a flow of liquid through the pumpbox. The first inlet defines a first flow velocity region between the first inlet and the second inlet and a second flow velocity region between the second inlet and the discharge outlet. The first flow velocity is lower than the second flow velocity to facilitate flotation of a low specific gravity portion of the feedstock through the first region toward an upper surface of the liquid accumulated in the reservoir volume.Type: GrantFiled: December 15, 2010Date of Patent: March 3, 2015Assignee: Suncor Energy Inc.Inventors: Thomas Charles Hann, William Nicholas Garner

Patent number: RE45415Abstract: An oxygen emitter which is an electrolytic cell is disclosed. When the anode and cathode are separated by a critical distance, very small microbubbles and nanobubbles of oxygen are generated. The very small oxygen bubbles remain in suspension, forming a solution supersaturated in oxygen. A flow-through model for oxygenating flowing water is disclosed. The use of supersaturated water for enhancing the growth of plants is disclosed. Methods for applying supersaturated water to plants manually, by drip irrigation or in hydroponic culture are described. The treatment of waste water by raising the dissolved oxygen with the use of an oxygen emitter is disclosed.Type: GrantFiled: September 28, 2011Date of Patent: March 17, 2015Assignee: Oxygenator Water Technologies, Inc.Inventor: James Andrew Senkiw
