  • Patent number: 11058975
    Abstract: A filtering apparatus has filtering elements (11) in a filter housing (1), a filter inlet (7) and a filter outlet (9). During filtration, one of the filter elements (11) can be back-flushed by a back-flushing device (45, 49), having a pressure control device (19). The pressure control device has a hydraulic accumulator (19), with a fluid chamber (47) fillable during filtration with clean fluid and connectable for back-flushing via a back-flushing guide (45) to the clean side (29) of the filtering element (11) to be cleaned. For back-flushing, a further fluid chamber (48) of the hydraulic accumulator (19) is subjected to gas pressure. By resultant movement of a separator (59) of the hydraulic accumulator (19), the filling amount of the clean fluid is dispensed for the back-flushing.

  • Patent number: 10967298
    Abstract: An acoustic standing wave is utilized to separate components from a multi-component fluid, such as oil from an oil-water mixture, or cells entrained in a fluid, in a fluid flow scheme with an acoustophoresis device. For example, the flow scheme and device allows for trapping of the oil as the oil coalesces, agglomerates, and becomes more buoyant than the water. A driver and controller for the acoustophoretic device accommodate variable loading as the components are separated, thereby improving separation efficiency.

    Abstract: A composition and method of inhibiting corrosion and white rust on metal components in a water system. The composition preferably comprises an amino-acid based polymer (most preferably a polyaspartic acid or a salt thereof), hydroxyphosphonoacetic acid, and a second phosphonic acid (preferably a phosphonocarboxylic acid), and does not require the use of regulated metals. The composition is effective even in the presence of biocides. A preferred method of inhibiting white rust comprises adding an amino-acid based polymer or hydroxyphosphonoacetic acid or both to the water system. A preferred method of inhibiting corrosion or white rust comprises adding an amino-acid based polymer, hydroxyphosphonoacetic acid, and a phosphonocarboxylic acid to the water system. Preferably the active concentrations are at least 3 ppm each of the amino-acid based polymer and hydroxyphosphonoacetic acid when added to a volume of water in the water system.

  • Patent number: 10345127
    Abstract: A cassette module for a differential flowmeter has a first channel and a second channel which carry fluid during operation of the differential flowmeter and are permeated by a magnetic field during operation of the differential flowmeter, each having an electrode pair arranged on the first channel and on the second channel. A flow difference between the first fluid-carrying channel and the second fluid-carrying channel can be determined by comparing the signals on the first electrode pair and on the second electrode pair. The first channel has an additional section that is permeated by the magnetic field during operation. Another electrode pair is arranged in the additional section, so that a change in the measurement conditions can be detected by comparing the signal on the first electrode pair and on the additional electrode pair.

  • Patent number: 10252920
    Abstract: Data relating to fluid dynamics is obtained using a flow field sensor that measures acceleration and angular velocity of the sensor on three axes. Ballast control allows the sensor to obtain neutral buoyancy within the fluid. The sensor is effective in opaque fluids and closed containers as data is stored in a removable memory. Froth flotation systems are among the applications for the sensor. The small size, the geometry, and the center of mass of the sensor allow it to follow the flow field in a vessel without material disruption of the flow field or weight-induced angular displacement.

  • Patent number: 10087087
    Abstract: A water distribution system having a dual use water treatment unit. The same water treatment unit can be used to treat water supplied from a fill port to a storage tank during a fill operation, as well as water leaving the storage tank for supply to one or more points of water use during a supply operation. When a diverter valve is in a fill position, water supplied to the fill port can flow through the diverter valve and to the water treatment unit for treatment then to the storage tank for storage. When the diverter valve is in a supply position, the water from the storage tank can be delivered using means for pressurizing water to the same treatment unit for treatment, then through the diverter valve and to a point of water use device.
