  • Patent number: 11478732
    Abstract: Systems and methods determine a filter efficiency of a fluid filter. A characteristic of fluid flow of a fluid is monitored at a first point and at a second point on a flow path of a fluid filter. A particle absorption level of the fluid filter is determined that is a difference in the characteristic of the fluid flow at the first point and the second point. The particle absorption level of the fluid filter is at a particle absorption saturation level based on the difference in the characteristic of the fluid flow at the first point and the second point. The particle absorption saturation level is an indicator that the particles retained by the fluid filter is decreased and replacement of the fluid filter is required to increase the particles retained by the fluid filter to be above the particle absorption saturation level.

  • Patent number: 9616164
    Abstract: 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.

  • Patent number: 9556039
    Abstract: There is disclosed a unique water treatment system which incorporates a unique primary valve. The primary valve comprises an interconnected first part and second part. The first part attaches to a water source and provides untreated water to water treatment units which are controlled by the second part of the primary valve. Untreated water flows to a first water treatment unit and subsequently through a valve to the second part of the primary valve and to use or to a second water treatment unit. From the second water treatment unit the water flows to the second part of the primary valve and to use. The second part of the primary valve has a unique bore and slideable shaft valve structure. The water treatment units can purify the water and/or add substances to the water.

  • Patent number: 9440169
    Abstract: A fuel filtration system includes an electric pump, a filter assembly, and conduits for fluidly connecting the pump and filter assembly in series with a fuel tank to define a kidney filtration loop. The filter assembly includes a filter assembly head, including attachment openings therethrough, and a filter exchange module, including a mounting plate having externally threaded mounting connectors extending outwardly from one face thereof and internally threaded bores opening through another face thereof. In a mounted configuration, a fuel filter is threaded onto each mounting connector such that the filter is fluidly aligned with a fuel flow opening through the mounting plate, fasteners are positioned through the attachment openings and threadably received within the bores, and fuel flow passages of the filter assembly head define a flow distribution in which one pair of filters is fluidly in parallel and another pair of filters is fluidly in series.

  • Patent number: 9364836
    Abstract: A method and apparatus for removing metallic material from a circulating well fluid stream provides a treatment vessel that is divided into first and second sections. Each of the sections includes a magnetic field that can be in the form of one or more magnets. In one embodiment, multiple magnets are provided in each of the sections. 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.

  • Patent number: 9176041
    Abstract: 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.

  • Patent number: 8980103
    Abstract: 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.
