  • Patent number: 9896355
    Abstract: A waste water treatment system utilizing a series of individual modules which, when assembled, form a beginning contaminate collection chamber attached at the starting end of a main fluid treatment tank in which is housed an array of anodes and cathodes. A center contaminate collection chamber can be attached at the oppose end of the main treatment tank which provides an internal fluid pathway to allow fluid transfer from the first treatment tank into a second treatment tank. Alternatively, the center contaminate collection chamber can be used when multiples of treatment tanks are assembled to work in tandem, or an ending contaminate collection chamber can be attached to an ending treatment module to complete the expandable waste water treatment system. Expandability of the system can therefore accommodate various waste water treatment mechanisms, residence time and manner of treatment.

  • Patent number: 8968576
    Abstract: A method of treating contaminated air, gas and surfaces is accomplished through the nebulization of gas and/or liquid oxidants through a field of electromagnetic radiation or sonic waves. The contaminated gas and/or liquid streams are blended with gaseous and/or liquid oxidants by the nebulizer and directly injected in the energy field. Free radicals produced from oxidants in the presence of the energy field instantaneously oxidize a large effective surface area of the contaminated media. Surfaces are treated more efficiently with the energy field situated directly above and parallel to but not on the surface; a high-frequency energy field may be used to create a large concentration of free radicals without damaging the surface in a collimated beam of the field situated parallel to the surface. A catalyst may be employed at the tip (i.e. discharge orifices of gas and/or liquid) of the nebulizer or blended into the nebulized cloud to increase the formation of free radicals.

  • Publication number: 20100181260
    Abstract: A method and apparatus for treating water such as ballast water in ships in order to eliminate aquatic organisms in the water. The water is led under pressure through a conduit into a chamber of greater cross-section than that of the conduit so that an abrupt reduction in pressure occurs. Cavitation ensues, leading to the release of dissolved gases. Ultrasonic vibration is generated and is applied to the water, exerting a pounding effect that weakens or destroys the organisms present. Other means may be used to generate further mechanical, electrical, and chemical forces in the water which attack the organisms.

  • Patent number: 7757866
    Abstract: In an embodiment, axially-fed slurry can be continuously separated into clarified liquid, stripped gas, and thickened sludge in radial counterflow between counter-rotating coaxial centrifugal impellers. One impeller comprises an annular crossflow filter through which liquids are extracted. At the periphery of the impellers, where they are narrowly separated, the sludge is shear thickened into an extruded paste. Suspended solids in the feed pass over the surface of the rotating annular crossflow filter by the shear lift effect, and the vortex-wall interaction jets water radially inward from the periphery, dewatering the sludge. Evolved gases, oils, and fractions lighter than water flow radially inward to the impeller axis through radial vortices in a shear layer between the impellers, and are extracted through an axial exhaust conduit. Feed has long residence time so that separation is complete and continuous. Municipal wastewater, produced water, beverages, food, and scrubber sludge are discussed.

  • Publication number: 20100126942
    Abstract: The present invention is an ultrasonic device with the transmitting head located outside a housing enclosure while radial mode PZTs and tail mass are located inside the housing enclosure. The ultrasonic device and related process are useful for any process involving supplying ultrasonic energy to a liquid, including controlling algae and decontaminating liquids with multiple ultrasonic transmitters driven at variable frequencies. A broad range of algae can be successfully controlled and various liquids can be decontaminated or otherwise processed in a rapid and effective way. Each transmitter is housed in an enclosure that can float on the surface of tanks; pools, reservoirs, lakes, ponds, and water and waste-water facilities. Alternatively, the transmitters can be attached to a structure and positioned with the transmitting head immersed into the liquid. The exposed transmitting head efficiently transmits ultrasonic energy to the liquid.

  • Patent number: RE43332
    Abstract: The present invention relates to a method for disinfecting and purifying liquids and gasses comprising; a) passing said liquids or gasses through a reactor or a combination of reactors, having a truncated compounded concentrator geometry; and b) simultaneously delivering and concentrating diversified electromagnetic and acoustic energies into a specific predetermined inner space of said compounded concentrator reactor, forming a high energy density zone in said reactor or reactors over a predetermined period of time. The reactor according to the present invention is preferably a compounded parabolic concentrator or a compounded ellipsoidal concentrator. The electromagnetic energy delivered and concentrated into and inside the reactor can be of any range of the electromagnetic spectrum, such as ultra-violet, visible, infra-red, microwave etc., or combination thereof. The acoustic energy is of any suitable frequency.
