    Abstract: The invention relates to a method of performing an optical or electrical measurement in a sample of a disperse fluid, the sample comprising particles and a fluid. The method comprises the steps of: a) positioning the sample in a microfluidic cavity having a resonance frequency, b) subjecting the sample, in the cavity, to an acoustic standing wave configured for causing the particles to congregate in at least one first region of the cavity, thereby causing the fluid to occupy at least one second region of the cavity, wherein the frequency of the acoustic standing wave is varied between a frequency below the resonance frequency and a frequency above the resonance frequency, and c) performing an optical or electrical measurement in the fluid in at least one of the at least one second region of the cavity. Varying the frequency ensures reproducible results. The invention also relates to a system therefore and a method and system for measuring hematocrit.

  • Patent number: 9023214
    Abstract: The invention provides a method and apparatus for creating plasma particles and applying the plasma particles to a liquid. Liquid feedstock (e.g., water and/or hydrocarbons mixed with biomass) is pumped through a pipeline; the single-phase stream is then transformed into a biphasic liquid-and-gas stream inside a chamber. The transformation is achieved by transitioning the stream from a high pressure zone to a lower-pressure zone. The pressure drop may occur when the stream further passes through a device for atomizing liquid. Inside the chamber, an electric field is generated with an intensity level that exceeds the threshold of breakdown voltage of the biphasic medium leading to a generation of a plasma state. Furthermore, the invention provides an energy-efficient highly adaptable and versatile method and apparatus for sanitizing water using plasma particles to inactivate biological agents contaminating water.

    Abstract: An apparatus for providing metal ions to a fluid waste stream includes a housing having an inlet port and an outlet port through which the fluid waste stream enters and exits the housing. Within the housing and between the inlet and outlet ports is an electrode assembly that includes first electrode ring assemblies and second electrode ring assemblies. Each first electrode ring assembly includes a first tubular section formed of electrically insulative material and has an interior through which the fluid waste stream flows. One or more first electrode plates span the interior of the first tubular section and contact the fluid waste stream. Each second electrode ring assembly includes a second tubular section formed of electrically insulative material and has an interior through which the fluid waste stream flows. One or more second electrode plates span the interior of the second tubular section and contact the fluid waste stream.

  • Patent number: 8992848
    Abstract: The present invention relates to a delivery apparatus for delivering electromagnetic energy into a solution. The delivery apparatus comprises a coil means arranged within an outer housing for delivering a magnetic field into the solution, a voltage assembly means coupled to the coil means for delivering an electric field into the solution, and connection means for delivering an electromagnetic signal to the coil from electromagnetic signal generation circuitry contained within the housing. The arrangement of the present invention confers significant physical stability on the delivery apparatus and ensures that heat generated by heat generating components of the apparatus is conducted away from the electromagnetic signal generation circuitry so that the apparatus can be operated continuously.

  • Patent number: 8906242
    Abstract: Disclosed is an improved water treatment apparatus. The treatment apparatus is pressurized and operates on a continuous flow of fluids which are subjected to hydrodynamic waves, acoustic ultrasonic waves in combination with injected ozone. The treatment tank includes a tangential inlet that induces a rotating flow into the tank thereby increasing the mixing of the ozone within the effluent. The ozonated fluid is further electro chemically treated with DC current. The treatment tank provides a cost efficient and environmentally friendly process and apparatus for cleaning and recycling fluids as contaminated as frac water, used to stimulate gas production from shale formations, as well as other types of fluids having various levels of contaminants such as aerobic and anaerobic bacteria and suspended solids.

    Abstract: The filtration membrane (102) includes an ozone producing circuit (120) having a plurality of electrically conductive lines (122, 124) disposed directly upon an active surface (102a) of the filtration membrane (102). The electrically conductive lines (122, 124) form spaced-apart and interleaved anodes (122) and cathodes (124). Ozone and other mixed oxidants coming from the ozone producing circuit (120) will prevent and/or remove biofilm formations on the active surface (102a) without the need of an outside source of gas. They can also remove at least some undesirable dissolved gases from the liquid being purified.

  • Patent number: 8865003
    Abstract: A method for separating, or removing, particulate material, e.g., blood cells, from a sample of fluid, e.g., whole blood of a patient, in which the particulate material is suspended. In the case of separating blood cells from blood plasma or blood serum, the resulting samples of blood plasma or blood serum can be used for in vitro diagnostic applications. In normal practice, a whole blood sample of a patient are provided and then introduced into an apparatus that contains a flow channel. An acoustic field, which contains acoustic standing waves from external ultrasonic transducers, is located within the flow channel. Laminar flow is maintained in the flow channel. Blood cells and platelets are separated from blood plasma or blood serum at the end of the flow channel and collected. The method described herein allows fluid components to differentially migrate to areas of preferred acoustic interaction.
