  • Patent number: 10954140
    Abstract: A system and method of the purification of drinking water, ethanol and alcohol beverages is based on the action of hydrodynamic cavitation processing of microbiological and chemical contaminants, micro particles and colloidal particles. The fluid flow moves at a high rate through a multi-stage cavitation device and filtration module to generate hydrodynamic cavitation features in the fluid flow. The cavitation features generate changes in the velocity, pressure, temperature, chemical composition and physical properties of the liquid. The cavitation features also prevent the deposition of contaminants upon and remove contaminants from the surface of the filter module, reduce the load on the filter elements and increase the life of the filter module.

The flow direction reverses from up before the wheel to down through a tube after the wheel. The solids are flung to the tube periphery and the fluid reverses direction to go back up to a screen before reaching the eductor suction connection.

  • Publication number: 20150021281
    Abstract: A hybrid scavenger operates downstream of a separator such as a gunbarrel separator for petroleum production. The separator may be overdriven to maximize use of a permitted reinjection rate. The hybrid scavenger then extracts water from the oil and oil from the water without having to treat the entire stream of incoming production fluids.

  • Patent number: 8919573
    Abstract: A system for purifying non-potable water to make said water potable includes an intake pump for bringing the non-potable water into the system. At least one centrifugal separator separates the non-potable water into suspended solids, saline water and oil. At least one ozone contact chamber injects ozone into a water stream being injected into at least one of the at least one of the centrifugal separators. A series of progressive filtration components are used for progressively filtering the saline water from the at least one centrifugal separator. The salinization filters then desalinate the progressively filtered saline water.

  • Publication number: 20140367348
    Abstract: Hydrodynamic separation of suspended particles using curved channels offers advantages in many applications, since it is a fast continuous flow technology that can handle neutrally and near neutrally buoyant particles without the need of a physical barrier or the addition of chemical aids. Designs are provided for a flow splitter at the end of the separation channel, to maintain smooth, counter-vortex-free laminar flow and improve particle separation efficiency while reducing clogging and fouling propensities.

  • Publication number: 20140367346
    Abstract: A reduced air hydrocyclone unit includes a hydrocyclone having a cylindrical section, a conical base having an underflow outlet formed in its apex, and an overflow outlet on an upper end of the cylindrical section. An underflow basin collects underflow material. Overflow material flows through an overflow line. An exhaust fan of the reduced air hydrocyclone unit withdraws from the overflow material in the overflow line a portion of an amount of air introduced through the apex of the hydrocyclone. A reduced air fluid system includes the reduced air hydrocyclone unit, a fluid tank in fluid communication with the overflow line of the reduced air hydrocyclone unit, and a reduced air hopper for mixing a solid material with a fluid contained in the fluid tank to form a slurry. A liquid barrier inlet of the reduced air hopper creates a liquid barrier to prevent air introduction into the slurry.

  • Patent number: 8906203
    Abstract: A system enables the use of solar heat energy together with electromagnetic energy and optionally energy produced during fermentation of organic products to produce fresh water from salt water, wastewater and water vapor contained in the atmosphere. The resulting fresh water can optionally be rendered drinkable by adding mineral salts at the desired concentration. A method and reactors combine electromagnetic and solar heating steps and optionally heat exchanges with a hot gas originating from combustion, to evaporate droplets of a spray produced from salt water or wastewater. The vapor obtained is separated from the salt particles or agglomerated impurities during evaporation using a cyclone system. The vapor can then be transported over a large distance before being condensed by bearings, in order to separate the water from any additives or impurities that may be present. Additives can be used to lower the vapor pressure of the liquid water and to facilitate droplet fractionation.
