Manifolds attach to an influent and to an effluent of the treatment vessel. Each manifold enables selective transfer of fluid to either of the selected sections. Similarly, discharge of circulating fluid can be from either of the sections via a discharge manifold. The treatment vessel enables continuous treatment by valving fluid flow so that only one section need be used at a time in order that the other section could be serviced for removing collected metallic material from the magnetic field or from the magnets.Type: GrantFiled: June 16, 2014Date of Patent: June 14, 2016Assignee: PETROLEUM SPECIALTY RENTAL, LLCInventors: Pat Williamson, Steve Callegari, Steve Callegari, Jr., Raphael Fontenot, Homer Boudreaux, Larry Foley

Patent number: 9248226Abstract: A device and method for detecting recirculation for an extracorporeal blood treatment apparatus and an apparatus with a device for detecting recirculation are based on targeted haemodilution by administration of a substituate bolus, causing a pressure change in venous and arterial branches of the extracorporeal circuit due to a viscosity change of flowing fluid. Recirculation is detected based on detection of the pressure change. The device includes a control unit cooperating with a device for conveying blood and a device for supplying substituate. The control unit provides an operating mode for detecting recirculation, in which blood flow rate is reduced during administration of a substituate bolus. With simultaneous substituate bolus administration and reduction of blood flow rate, the composition of fluid flow is optimized for detection of recirculation, so that fairly large pressure changes result in venous and arterial branches, thereby improving sensitivity and reliability of the measurement method.Type: GrantFiled: September 20, 2013Date of Patent: February 2, 2016Assignee: Fresenius Medical Care Deutschland GmbHInventor: Thomas Nuernberger

Patent number: 9176041Abstract: A particle quantifier includes a filter with a predetermined number of pores of a first predetermined size, a pump, and a fluid path from the pump to the filter. A pressure sensor is responsive to fluid pressure in the fluid path, and a processing module is responsive to the pressure sensor. The pressure increase of a sample fluid in the fluid path is determined as it is pumped through the filter and particles in the fluid are trapped by the filter. This pressure increase is compared with calibration data and an estimate is made concerning the concentration of particles greater than a second predetermined size present in the sample.Type: GrantFiled: June 19, 2012Date of Patent: November 3, 2015Assignee: Spectro Scientific, Inc.Inventors: Thomas G. Barraclough, Stephen D. Lawrence

Patent number: 8980103Abstract: Disclosed herein are a ballast water treatment system having a back-pressure formation unit and a control method thereof. Back pressure in a filtering unit is checked and formed during a back washing operation for a filter of a filtering unit, thus enabling efficient back washing operation. Both a method of physically filtering ballast water using the filter and a method of sterilizing ballast water using ultraviolet rays are used to treat ballast water, thus preventing secondary contamination due to byproducts, and preventing the contamination of a ballast tank. A flow rate of ballast water introduced into an ultraviolet treatment unit is controlled such that the efficiency of the ultraviolet treatment unit is not reduced, while back pressure is formed in the filtering unit, thus increasing the overall treatment efficiency of the ballast water treatment system. Further, the filtering unit or the ultraviolet treatment unit may be automatically washed.Type: GrantFiled: February 25, 2011Date of Patent: March 17, 2015Assignee: Panasia Co., Ltd.Inventors: Soo-Tae Lee, Tae-Sung Pyo, Sang-Gyu Cheon
