  • Patent number: 11866353
    Abstract: The present disclosure provides for methods and systems for separating ultrafine particulate pollutants from aqueous suspensions. The present disclosure provide for methods and systems that can reduce the amount of ultrafine particulate pollutants from aqueous solutions, for example storm water runoff, which are not readily or easily removed using current state of the art techniques. In general, methods of the present disclosure provide for removing a portion of target ultrafine particulate pollutants using magnetic nanoparticles, which form aggregates with the ultrafine particulate pollutants. After a time period a magnetic field is applied and the aggregate can be separated from the aqueous suspension. Subsequently, the aggregates can be broken down and the magnetic nanoparticles recycled or reused while the ultrafine particulate contaminants are further processed, recycled, or disposed of.

  • Patent number: 11565274
    Abstract: Provided is a magnetic separator in which even when content of a magnetic sludge in a liquid to be treated increases, recovery performance of the magnetic sludge is less likely to degrade and a malfunction of the device is less likely to occur. A part of an outer peripheral surface of a magnet drum is immersed in a flow of the liquid to be treated containing the magnetic sludge. A removing mechanism removes the magnetic sludge on the outer peripheral surface of the magnet drum from the outer peripheral surface of the magnet drum. A magnetic sludge containing information acquisition device acquires magnetic sludge containing information relating to a content of the magnetic sludge contained in the liquid to be treated. A control device changes a magnetic sludge removal capability of the magnet drum depending on the magnetic sludge containing information acquired by the magnetic sludge containing information acquisition device.

  • Patent number: 10724930
    Abstract: Sandwich separation is based on forming a sandwich complex with a magnetic bead, buoyant bead, and a target. Once a sandwich formation is created, the sandwich can be separated using its dual physical properties, namely magnetism and buoyancy. Sandwich separation is highly specific, allows for removal of the beads that do not have any attached target, and reduces the number of background beads. Sandwich separation can also be used to allow for target detection in raw specimen. Also, improvement of detection capability is accomplished by performing AMBR measurements on a solid interface, where the rotational period speeds up and allows for dramatically reduced time-to-result.

  • Patent number: 10702811
    Abstract: A filter device for fluids includes a housing (1) accommodating a filter element (5). The housing has an inlet (47) for the supply of fluid to be purified to a non-filtrate chamber (49) of the housing (1) and has an outlet 42 for the filtrate. The non-filtrate chamber is separated from a filtrate chamber (46) of the housing (1) by the filter medium (33). A magnetic field-generator unit (57) is arranged inside the non-filtrate chamber (49). An adhering surface a sleeve or casing (51) attracts ferromagnetic particles by a magnetic force effect. In the non-filtrate chamber (49), the sleeve (51) extends outside of the respective filter element (5) parallel to the inlet (47) and transversely to the outlet (42). The non-filtrate chamber (49) at least partially encompasses the outlet (42) at the point of transition to the filtrate chamber (46).

  • Patent number: 10670436
    Abstract: Provided here are systems and methods to determine the flow rate of fluids that have magnetizable components. One such flow rate measurement apparatus contains a magnetization unit that magnetizes fractions of magnetizable components present in the fluid; a magnetic field detector with a probe to detect the magnetic field associated with the magnetized fractions of the fluid; and a processing circuitry to determine velocity of the fluid from time taken for the magnetized fractions to travel from the magnetization unit to the magnetic field detector and the distance between the magnetization unit and the magnetic field detector. Flow rate of the fluid is then subsequently determined from the velocity and the cross-sectional area of the conduit of the flow measurement apparatus. Various other embodiments may be disclosed and claimed.

  • Patent number: 10618828
    Abstract: An apparatus for reducing and inhibiting scale formation in water conduits is disclosed. The scale reducing apparatus has at least two stages, each stage containing one or more conduits therein surrounded by magnets. The magnets form a strong, substantially uniform magnetic field in the conduit(s) which is substantially perpendicular to the flow of water therein. Dissolved ions in the water interact with the magnetic field and may as a result be forced into contact with one another to form one or more non-dissolvable solids. The reduction in dissolved ions reduces and/or inhibits the formation of scale in the water supply lines of a structure, thus increasing the life of the conduits, appliances, and other structures where scale may form.

  • Patent number: 10613104
    Abstract: An assay to determine anticoagulants in a blood or blood plasma sample, wherein the assay comprises analyses with at least two wet chemistry prothrombine time (PT) methods. The assay comprises measuring PT in a first reaction mixture with a first PT method and measuring PT in a second reaction mixture with a second PT method, wherein the concentration of blood or blood plasma in the second reaction mixture differs from the concentration of blood or blood plasma in the first reaction mixture. The PT methods are calibrated to give the same or approximately the same PT results for reference samples which lack anticoagulants of interest for the assay. Further, calculating a difference in PT from the measurements, wherein if the difference in PT is 1) significant, this is indicative of a presence of anticoagulants in the sample, or 2) non-significant, this is indicative of an absence of anti-coagulants above detectable level in the sample.
