Patent number: 6790352Abstract: An apparatus for treating water contaminated with metal sulfates and sulfuric acid such as acid mine drainage (AMD) which in part recycles high pH effluent from later steps in the process back to the earlier steps of the process. The recycled high pH effluent added with magnesium hydroxide to the entering AMD generates precipitates separable from the stream to leave sulfate ladened water. A tangential filtering process is used to separate the sulfate ladened water into one stream of pure water and a second stream containing sulfate. One portion of the second stream is treated with ammonia to yield a cake of ammonia sulfate and aqueous ammonia. Ca(OH)2 is added to another portion of the second stream to produce calcium sulfate cake and the high pH effluent that is recycled back to the first step in the cycle.Type: GrantFiled: July 13, 2000Date of Patent: September 14, 2004Inventors: Stephen Ray Wurzburger, J.

Patent number: 6517719Abstract: A storage tank includes an oil and water separator in which the frontal area of the coalescers is increased relative to known arrangements of coalescers in oil and water separators. By arranging the coalescers such that the surface area of the coalescers is increased, the efficiency of the coalescers is increased. In some preferred embodiments, the coalescers are arranged in a bank with free flow fluid paths between the coalescers in the bank, each of the paths being closed by a baffle on one end and open on an opposite end, and the baffles are arranged such that the open and closed ends of paths alternate. In other preferred embodiments, the coalescers are arranged in a tubular fashion and fluid flows from the outside surface of the tube through the coalescers and out a central path.Type: GrantFiled: November 28, 2000Date of Patent: February 11, 2003Assignee: Xerxes CorporationInventor: John Burwell

Publication number: 20030019800Abstract: A self-cleaning pre-filter system generally comprises a system inlet; a sediment filter having a filter inlet in selective fluid communication with the system inlet, a selectively openable drain port and a filter outlet, separated from the filter inlet and the drain port by a filter screen; a pressure accumulator having a first chamber in open fluid communication with the filter outlet and having a sealed second chamber containing a compressible medium, the first chamber and the second chamber being separated one from the other by a flexible diaphragm; and a system outlet in selective fluid communication with the filter outlet and the first chamber. A controller operates valves to periodically back flush the sediment filter utilizing energy stored in the pressure accumulator. Any detritus removed from the filter screen during the back flush process is immediately discharged from the system through the drain port.Type: ApplicationFiled: July 25, 2001Publication date: January 30, 2003Applicant: LANCER PARTNERSHIP, LTD.Inventors: Michael T.

Publication number: 20030010719Abstract: A method and device for renal replacement therapy is described that sterile-filters solution that can subsequently be used as a replacement fluid in the same unit. The devices and methods include a pump that can be reversed from its normal forward-pumping direction to sterilize a container of replacement fluid to produce sterile replacement fluid. The sterile replacement fluid is captured in a fluid bag. Upon sterilization of the contents of the container, the pump switches to run in its normal forward-pumping direction. The sterile replacement fluid produced by the previous process is now injected into a patient to perform renal replacement therapy. The waste produced during the renal replacement therapy can be trapped in the container that previously held the non-sterile solution. Systems for sterile filtration and subsequent renal replacement therapy that include pre-connected, sterilized, disposable kits for fluid management and batch collection of sterilized fluid are also described.Type: ApplicationFiled: July 12, 2001Publication date: January 16, 2003Applicant: NxStage Medical, Inc.Inventors: James M.

Publication number: 20030010717Abstract: Systems and methods handle air and rinsing fluid during fluid processing. The systems and methods eliminate air from a fluid processing system prior to, during, and after use. The systems and methods provide a connector assembly for establishing fluid flow from a fluid source. The connector assembly has discrete first and second passages that prevent communication between the fluid in first passage and the fluid in the second passage. Prior to system use, the connector assembly may be utilized in a priming function to remove residual air from a fluid circuit prior to use. The connector assembly may also be utilized after use to perform a rinse-back function. The rinse-back function serves to remove residual fluid from the system after use. The connector assembly can comprise two, single lumen connectors or one connector with two lumens.Type: ApplicationFiled: July 13, 2001Publication date: January 16, 2003Applicant: NX Stage Medical, Inc.Inventors: James M.

Patent number: 6506298Abstract: A biofiltering system for treating wastewater effluent (e.g. from a septic tank) through a bed of peat 16 overlying an effluent absorption area 12 and into the earth beneath 14. The bed of peat has a predetermined biofiltering capacity. A fluid flow regulator 18 upstream from the peat is adapted to allow the effluent to flow at a rate greater than the peat bed biofiltering capacity. However, a distribution system arranged over the peat is configured such that wastewater received from the fluid flow regulator flows through the peat bed at a rate no greater than the peat bed biofiltering capacity. The distribution system 20 includes a plurality of spaced-apart, elongated distribution conduits 72 having discharge orifices 74 spaced longitudinally therealong. The biofiltering system allows large quantities of wastewater to be efficiently treated irrespective of the flow rate thereof.Type: GrantFiled: April 10, 2001Date of Patent: January 14, 2003Assignee: Berger Group Ltd.Inventor: Belhumeur Albert

Patent number: 6495039Abstract: An in-line biological liquid filtration system and method comprises a collection container for receiving biological liquid. A filter is located downstream of the collection container and in fluid flow communication therewith. A storage container for receiving filtered biological liquid is located downstream of the filter and the storage container is in fluid flow communication with the filter and with the collection container. An additive solution is located in the storage container. At least one automatic control member automatically restricts a flow of biological liquid or additive solution when flowing the liquid or solution between the collection container and the storage container.Type: GrantFiled: June 27, 2000Date of Patent: December 17, 2002Assignee: Whatman Hemasure, Inc.Inventors: Eric K.

Patent number: 6488860Abstract: The invention relates to a device and a method for separating whole blood into blood components. The device has a collecting container for collecting whole blood, a primary container, and one or a plurality of satellite containers downstream from the primary container. The collecting container is connected to the primary container via a branch line containing a leucocyte filter. In addition, a bypass line is provided between the collecting container and the primary container for creating a fluid connection that circumvents the leucocyte filter. The primary container is also connected, via an additive line, to an additive container containing an additive agent for storing a blood component. The method involves collecting the donor's whole blood in the collecting container and conveying it, via the bypass line, into the primary container. The whole blood located in the primary container is then separated by centrifuigation into an erythrocyte layer and a mixed layer of blood plasma and thrombocytes.Type: GrantFiled: March 24, 1998Date of Patent: December 3, 2002Assignee: Fresenius AGInventors: Giorgio Mari, Paolo Verri
