Abstract: A closed system for continuous removal of ethanol and other compounds in an aqueous solution includes a centrifuge for removing debris for providing a filtered aqueous solution. A transfer pump and flow control valve control the flow and pressure of the filtered solution. A vacuum pump provides a negative pressure within a boil chamber. An internal heating element within the boil chamber receives the filtered solution preheated by a closed loop heater for maintaining the internal boil chamber temperature. An internal up-spray header sprays droplets of the filtered solution in the boil chamber for controlling the surface area and contact time of the droplets within the boil chamber. The heated vacuum environment within the boil chamber results in the ethanol within the sprayed droplets and a stream of centrifuge off-gas, to be extracted as a vapor and prevent recombination with the filtered solution. A condenser condenses the vapor to liquid ethanol.

Abstract: A multi-phase separation system utilized to remove contaminants from fluids includes a pre-filtering module for filtering a contaminated fluid to provide a filtered contaminated fluid. A condenser module receives the filtered contaminated fluid and a contaminated gas phase for condensing the contaminated gas phase to a contaminated liquid. A phase reaction chamber converts the filtered contaminated fluid to a contaminated mist wherein the mist is subjected to a low energy, high vacuum environment for providing a first change of phase by separating into a contaminated gas phase and a liquid mist phase. The contaminated gas phase is carried out of the phase reaction chamber by a carrier air. A vacuum pump provides the low energy, high vacuum environment in the phase reaction chamber and delivers the contaminated gas phase to the condenser module for condensation providing a second change of phase.

Abstract: A saltwater intrusion prevention system for use at an interface between a fresh water body and a saltwater body includes a water recovery subsystem for recovering fresh water from a fresh water body. A retention reservoir in fluid communication with the water recovery subsystem receives and redirects the recovered fresh water. A saltwater intrusion barrier subsystem in fluid communication with the retention reservoir is positioned at an interface of the fresh water body and the saltwater body. The saltwater intrusion barrier subsystem includes a plurality of submerged return discharge ports for vertically ejecting the recovered fresh water for providing hydraulic mounding zone, and a fine air bubbler header for creating a mixing zone. The hydraulic mounding zone and the mixing zone increase the density of the fresh water for offsetting saltwater from the saltwater body.

Abstract: An ultrasonic device for detecting the presence of air in the fluid line of an IV infusion device comprises a transmitter and a receiver which are positioned to pinchingly engage a portion of the fluid line therebetween. Both the transmitter and receiver have convex-shaped lenses which contact and cause a slight indentation of the tube for enhanced coupling therebetween. The device may also have a pair of diametrically opposed pedestals which contact and engage the tube from a direction substantially at right angles to the axis defined by the transmitter and receiver. These pedestals help hold the tube between the transmitter and receiver. The device also includes self-testing electronic componentry which compares the transmitter-off output with the transmitter-on output to determine whether operation is normal or should be stopped because either there is air in the line or the electronic circuitry is faulty.
