  • Patent number: 9044747
    Abstract: An improved process for regenerating ion exchange resin, includes a regeneration step of displacing captured ions from the resin to regenerate its ion-capture functionality, followed by one or more fluid-employing post-regeneration steps such as a fluid displacement or rinse, a fluid transporting or mixing, and a rinse down to quality. To avoid problems of early leakage of weakly held ions such as boron, the post-chemical or postdisplacement steps use water that is essentially free of boron, or otherwise avoid localized contamination in the regenerated resin which is used in bottles or beds (30). A two-stage polish may be operated with modified lead/lag bottles. A detector (D) for an indicator condition (conductivity, silica breakthrough) between stages determines when to shift the lag bottle forward, and periodically both bottles are replaced.

  • Patent number: 8920658
    Abstract: Methods and apparatus for desolvating flowing liquid streams while retaining temporal resolution of dissolved substrates are disclosed. A novel small-scale self-regulating spray dryer preserves temporal resolution while desolvating a liquid chromatography eluent stream and depositing the solute onto an optical surface for infrared spectrographic analysis. The liquid eluent is pumped through a heated nebulizer to create a high-speed jet of solute containing liquid and solvent vapor. This jet is directed circumferentially inside a hot cylindrical cavity. Centrifugal force causes the larger liquid droplets to travel along the outer diameter of the cavity. The cavity surface is heated to cause the droplets to film boil. Film boiling reduces droplet contact with the cavity surface thereby retaining the solute in the droplets. The solute temperature is limited by controlling the pressure into which the solvent evaporates from the droplets.

  • Patent number: 8696981
    Abstract: The instant invention provides methods and apparatus for disinfecting a space, e.g., a hospital room, using chlorine dioxide. One aspect of the invention provides an apparatus for disinfecting a space. The apparatus includes: a chlorine dioxide gas generator; a sensor adapted and configured to measure the relative pressure inside the space and outside the space; and a computer operatively connected to the sensor and the chlorine dioxide generator, the computer adapted and configured to control the chlorine dioxide generator to operate only when the space is under negative pressure as compared to outside the space. Another aspect of the invention provides a method of disinfecting a space. The method includes: setting an apparatus as described herein in the space; and allowing the apparatus to determine if the space is under negative pressure. If the space is under negative pressure, the apparatus generates chlorine dioxide gas to disinfect the space.

  • Patent number: 8142633
    Abstract: A treatment system and method for continuous deionization of a biologically derived feed stream includes a plurality of electrodialysis units (3, 9, 10, 11, 12, 13) arranged in stages along a treatment line, and stages are controlled such that the feed stream attains a certain quality before entering the next stage. The feed and concentrate streams move in generally opposite sense along the line, matching fluid characteristics of dilute and concentrate cells. The treatment line has two or more stages. Systems may have phased staging operations, and cell constructions may adapt the electrodialysis units for enhanced processing of difficult process fluids. A controller sets operating potentials in different electrical stages, and simple control parameters optimize ion removal and current efficiency without polarization of the fluid. The invention also includes phased staging of reversal operation, and cell constructions or fillings that adapt the treatment cells for enhanced processing.

  • Patent number: 7794577
    Abstract: A spacer element (1) is disclosed having an integral screen for use in filled cell electrodialysis. The spacer (1) has a continuous portion (2) impermeable to flow and a screen (3) which spans a centrally-located flow treatment region that contains active treatment material, such as ion exchange beads. The screen (3) may perform a structural function, allowing operation at elevated pressure, and may also define a minimum gap between adjacent membranes and enhance mixing along the flow path and at cell boundaries. The spacer element (1) may be configured to enhance hydraulic filling of the cells, and cell architecture is readily implemented in a wide range of useful flow path geometries utilizing the screen spacer element (1).

  • Patent number: 7410581
    Abstract: A cross flow filtration apparatus for nanofiltration or reverse osmosis has pressure vessels with a plurality of filter cartridges in each vessel. A feed port is provided at an intermediate position on the side of the vessel, and two permeate flows or branches exit opposite ends of the vessel, and the first branch has a characteristically high “upstream” flux and quality, while the second is of lesser flux and/or quality. The system provides a high degree of moduarity, enhancing flux or yield at a reduced driving pressure or overall pressure drop. Centered or off-center port, and a stop or valve in the permeate stream may apportion flows between the two outlets. Staged systems may employ a first stage bypass to achieve a target quality with increased yield. A flow divider or adaptor permits the cartridges to fit and seal in the vessel and an installation tool or sleeve may facilitate installation or replacement of cartridges having a directional perimeter seal.
