Abstract: Rapid evaporation of water for desalination and dewatering using nanobubbles and micro-droplets is disclosed. Warm nanobubbles of air are injected into seawater or another water source to be treated, and the normal stasis of the nanobubbles is disrupted with ultrasonic energy. The nanobubbles implode and violently recombine into microbubbles. Energized by the effects of the nanobubble state change, these energetic, relatively high surface area microbubbles bubbles quickly rise to the surface of the water, creating an aerosol of micro-water droplets above the surface that is drawn into a dry, warm stream of air and rapidly evaporates, precipitating out salt crystals. The air is then cooled with a chiller, condensing the moisture in the air into fresh water.

Abstract: The technology disclosed is a two stage Indirect/Direct Evaporative Cooling (IDEC) cycle whose novel closed loop topology compels system convergence to a stable operating state, wherein air cooling takes place mostly in the indirect stage. The direct stage then serves principally as a water chiller for that process.

Abstract: A water hydration system for disposing of the water content of production fluid generated by a hydrocarbon well. The production water is processed to remove particulate matter, and then to separate the water from crude oil. The water is heated and pressurized and passed through a nozzle to produce a spray which flashes into steam in a duct carrying fresh air. The water vapor hydrates the air that is forced through the duct by a high capacity fan which blows the hydrated air into the atmosphere.

Abstract: The present invention is a wastewater treatment system utilizing a recirculating filter system comprising sand, gravel, or synthetic media. Septic effluent is continuously, or approximately continuously, dosed under pressure to the treatment media through pressure compensating drip irrigation emitters. The dosed effluent is treated and dispersed into a dispersal field using double coiled distribution lines that can alternate flow through emitters to rest the dispersal field. The double coil dispersal lines allow more emitters per unit area allowing treatment of the effluent more slowly and effectively.

Abstract: A hydro-thermal exchange unit (HTEU) for desalinating feed water in accordance with a humidification-dehumidification includes feed water, fresh water and gas conduit circuits for transporting feed water, fresh water, and gas, respectively. The unit also includes an evaporator through which a portion of the feed water conduit and the gas conduit pass. The evaporator causes evaporation of a portion of the feed water to produce vapor that is transported through the gas conduit. The unit also includes a condenser through which a portion of the gas conduit and the fresh water conduit pass. The condenser has input and output ports for coupling the gas and fresh water conduit circuits. The condenser extracts moisture from the vapor transported therethrough by the gas conduit. The extracted moisture is discharged through the fresh water conduit.

Abstract: A multi-stage bubble-column vapor mixture condenser comprises at least a first stage and a second stage. Each stage includes a carrier-gas inlet and a carrier-gas outlet, as well as a condenser chamber containing a condensing bath in fluid communication with the carrier-gas inlet and the carrier-gas outlet. The carrier-gas inlet is positioned to bubble carrier gas from the carrier-gas inlet up through the condensing bath, overcoming a hydrostatic head of the condensing bath. The carrier-gas outlet is positioned with an opening for carrier-gas extraction above the condensing bath, wherein the first-stage carrier-gas outlet is in fluid communication with the carrier-gas inlet of the second stage to facilitate flow of the carrier gas through the condensing bath in the condenser chamber of the first stage and then through the condensing bath in the condenser chamber of the second stage.

Abstract: The desalination system is a multi-stage flash desalination (MSF) system. Each stage has a P-shaped chamber having a flashing section extending vertically, a condensing section extending horizontally to overlay the flashing section of the next succeeding stage, and a demister (a device to separate liquid droplets entrained in vapor) separating the flashing section and the condensing section. One or more heat pipes extend between the condensing section of each stage and the flashing section of the next succeeding stage in order to transfer heat released by the condensing vapor in one section to the colder flashing section of the next succeeding chamber. The system includes a seawater-cooled condenser in the last stage to recover fresh water from the water vapor. The system may be modified by replacing or supplementing the condenser in the last stage with a thermal vapor compressor (TVC) to transfer vapor to the first stage.

Abstract: A phase shifting component of a waveguide comparator subsystem can effect a relative phase shift that advances an input signal A relative to an input signal B. A comparator component can then split those signals such that a first part of signal A and a second part of signal B are combined at a difference port, and a first part of signal B and a second part of signal A are combined at a sum port. The comparator can delay the phase of the second parts of the signals such that, with the relative phase shift of the phase shifting component, the first part of signal A and the second part of signal B are one-hundred eighty degrees (180°) out of phase at the difference port, and the second part of signal A and the first part of signal B are in phase at the sum port.
