  • Patent number: 9944541
    Abstract: Techniques for depleting target organisms in water include a waterproof transducer configured for ensonifying a container of water with low intensity sound at one or more ultrasound frequencies for a duration sufficient to prevent maturation of at least 90% of the target organism. In some cases the target organism is mosquito larvae. For example, a portable system for depleting target organisms in water includes a control system and a plurality of waterproof transducers. The system is configured for ensonifying a surface layer of water in an acoustic frequency range from about 40 kilohertz to about 100 kilohertz and in a power concentration range from about 35 milliwatts per milliliter to 100 milliwatts per milliliter for a duration in a range from about 1 to about 100 seconds.

  • Patent number: 9902630
    Abstract: It is to be understood that embodiments of the present invention provide apparatus and a method for pumping a liquid, for example to recirculate liquid in a liquid storage tank by means of a gas lift pump. A perforated extension at the top of a gas lift allows the apparatus to be used in circumstances where the depth of liquid in the tank may vary over a wide range. Gases other than air may be used in the gas lift, so as to change the acidity and the concentrations of dissolved gases, particularly oxygen, in the liquid. The gas may be introduced into the gas lift through a whistle that generates intense sound waves and couples them into the liquid. These features when used in combination have particular application against invasive species in the ballast water of ocean-going tankers.

  • Patent number: 9834464
    Abstract: A recursive fractal system provides low cost, high throughput removal of contaminants, selected compounds, and elements from a flowable medium. This includes low energy desalination of saltwater, and removal contaminants from waste water. A series of concatenated, self-similar, co-axially aligned fractal stages are provided for defining a flow path for receiving the flowable medium, such as salt water. The configuration of self similar fractal stages as a succession of venturis recursively accelerates and separates flow vectors at each stage without the need for pumping. The series of venturis have been found to accelerate the water to such an extent that an electro hydrodynamic field interaction is magnified at each successive stage, such that contaminants, heavy metals, salt, or other selected compounds are aggregated by an electromagnetic field signature, separated and extracted from the flowable medium.

  • Patent number: 9745548
    Abstract: Methods are disclosed for separating beads and cells from a host fluid. The method includes flowing a mixture containing the host fluid, the beads, and the cells through an acoustophoretic device having an ultrasonic transducer including a piezoelectric material driven by a drive signal to create a multi-dimensional acoustic standing wave. A drive signal is sent to drive the at least one ultrasonic transducer to create the multi-dimensional acoustic standing wave. A recirculating fluid stream having a tangential flow path is located substantially tangential to the standing wave and separated therefrom by an interface region. A portion of the cells pass through the standing wave, and the beads are held back from the standing wave in the recirculating fluid stream at the interface region. Also disclosed is an acoustophoretic device having a coolant inlet adapted to permit the ingress of a cooling fluid into the device for cooling the transducer.
