  • Patent number: 11644409
    Abstract: Reusable network of spatially-multiplexed microfliuidic channels each including an inlet, an outlet, and a cuvette in-between. Individual channels may operationally share a main or common output channel defining the network output and optionally leading to a disposable storage volume. Alternatively, multiple channels are structured to individually lead to the storage volume. An individual cuvette is dimensioned to substantially prevent the formation of air-bubbles during the fluid sample flow through the cuvette and, therefore, to be fully filled and fully emptied. The overall channel network is configured to spatially lock the fluidic sample by pressing such sample with a second fluid against a closed to substantially immobilize it to prevent drifting due to the change in ambient conditions during the measurement. Thereafter, the fluidic sample is flushed through the now-opened valve with continually-applied pressure of the second fluid.

  • Patent number: 11383992
    Abstract: The improved water purification system includes a water purification unit having a tap water inflow port for receiving a tap water inflow from a water supply system to produce relatively purified water and a brine water outflow having impurities concentrated therein. An RO filter having an RO membrane separates relatively unfiltered water flow into purified water and the brine water outflow. A flush flow activation chamber fluidly coupled to the brine water outflow includes a plunger for substantially occluding brine water outflow through the brine outflow port when seated, and substantially permits brine water outflow to exit the purification unit through the brine outflow port when unseated. Accordingly, the activation chamber generates back pressure within the water purification system to flash flow tap water inflow into the purification unit and through the RO membrane when the plunger moves from being seated to unseated, thereby substantially refreshing said RO membrane.

Automatic fill components may be provided for automatically actuating a fluid supply valve connected to an unfiltered fluid source. As filtered fluid is withdrawn from the lower reservoir, actuation of the fluid supply valve to an open position may permit unfiltered fluid to be supplied to the upper reservoir. Supply of unfiltered fluid to the upper reservoir may be stopped upon actuation of the fluid supply valve to the closed position.

  • Publication number: 20150090659
    Abstract: An upflow continuous backwash deep bed sand filter (UCBF) having a recycle line for returning carbonaceous denitrifying bacteria attached to biomass to the influent of the UCBF. The recycle line returns the biomass to the treatment process at a location upstream of the upflow continuous backwash filter. Further, a liquid level control unit is provided that reduces fluctuations and significant drop in the liquid level upstream of the upflow continuous backwash filter, thereby avoiding or minimizing flow turbulences, air induction, and undesirable wastewater aeration resulting in the need to dose excessive carbon source to remove dissolved oxygen in the aerated wastewater.

  • Patent number: 8974677
    Abstract: Fluid processing apparatuses and systems are disclosed. In some embodiments the fluid processing apparatuses include a movable enclosure, a plurality of filter housings disposed substantially within the movable enclosure, and a stand disposed within the enclosure. The filter housings are in fluid communication with one another. Each filter housing defines an elongate path and is configured to support a respective filter along the elongate flow path to filter a substantially continuous flow of fluid. The stand supports each filter housing such that the elongate flow path of each filter housing is substantially parallel to a vertical axis, wherein each filter housing is independently rotatable, relative to the stand.

  • Patent number: 8951418
    Abstract: A method of operating hydrocyclone comprising a separation chamber which in use is arranged to generate an internal air core for affecting a material separation process, comprises measuring both a vibrational parameter of the separation chamber and a stability parameter of the internal air core during operation of the hydrocyclone. The measurements are compared against predefined corresponding parameters which are indicative of a stable operation of the hydrocyclone and an operational parameter of the hydrocyclone is adjusted dependent on the comparison.

  • Patent number: 8936720
    Abstract: The present system and method in one embodiment limit a maximum instantaneous peritoneal volume to a comfortable level, while allowing the dialysis machine to advance to fill a prescribed volume whenever the drain ends after a minimum drain percentage has been attained. If a low drain condition occurs, the nominal fill volume is lowered and a therapy cycle is added, so that a prescribed total amount of fresh therapy fluid is used during therapy, maximizing therapeutic benefit. An allowable residual volume at the end of an incomplete drain is increased, thereby lowering the probability of a subsequent low drain condition.

  • Publication number: 20140367328
    Abstract: The invention provides structures, methods, and assemblies for processing fluid entering a treatment area. The invention also provides methods, apparatuses, and additional structures that are useful for managing storm water flow and inhibiting the flow of pollutants, debris, and other contaminants into drainage systems. One or more flow diverter pans are installed at one or more inlets of a treatment area, such as a bioretention treatment area or a storm water retention and detention system. The apparatus comprises a structural framework that can include a pan placed adjacent to an inlet of the treatment area, and internal walls extending upward from the floor of the pan and at least partially framing a bypass opening adjacent to the floor. Inlet and outlet openings of the pan define a primary flow route for fluid passing through the pan and to the surface of the treatment area. Inlet and bypass openings of the pan comprise a secondary flow route for fluid passing through the tray.
