A method may include providing a humidification-dehumidification unit proximate one or more abandoned wells, circulating a water feed through the one or more abandoned wells, using geothermal heat in the one or more abandoned wells to heat the water feed, directing the heated water feed to the humidification-dehumidification unit, and treating the heated water feed in the humidification-dehumidification unit to provide purified water.

A small processor produces potable water from contaminated water. Its components mount in a hermetically sealed housing, which include a boiler-condenser assembly and a compressor unit. Contaminated water is injected onto one or more aluminum shells' inside surface of the boiler-condenser assembly. Shell rotation enhances boiling heat transfer by causing the water to form thin films on the shells' inside surface. Shell rotation also enhances condensing heat transfer by assisting in removing the purified condensate from the shells' outer surface. The change of phase heat of condensation energy from vapor to liquid transfers through the shells to the boilers to cause boiling. Vapor boiled inside the boiler chambers flows toward the compressor, which raises the vapor's pressure and temperature to drive the process. Shell rotation causes centrifugal force that holds and directs concentrated un-boiled remaining water on the shells' inside walls towards the output pumps. Wipers mounted adjacent each shell's boiler surface smooth contaminated water. Wipers adjacent the condenser surfaces help remove condensate from that surface to present a clean condenser for improved condensation.

A multi-stage flash reversal unit includes a housing; plural stages located inside the housing; an evaporation port that receives a water feed having a first temperature; a condensation port that outputs a concentrated water feed having a second temperature, which is lower than the first temperature; and a cooling unit that cools down the concentrated water feed.

A system and apparatus for treating and disposing of produced water in conjunction with gas turbine exhaust gas, thereby avoiding problems associated with injecting produced water back into subsurface strata. The system is installed at or near the wellhead where produced water being treated is at a higher temperatures. Produced water is treated with ozone injection in a scrubber with heat applied through introduction of gas turbine exhaust gas. A wet scrubber unit with scrubber packing is used to clean emissions. A produced water pump is used to circulate produced water, and pump produced water through spray nozzles in the scrubber unit for use as the wet scrubbing agent. As produced water evaporates, evaporated salts and solids are continuously removed from the evaporator/scrubber unit by appropriate means, such as an auger system. The evaporated salts and solids are then treated via chemical stabilization in a mixing system with chemical reagents to prevent the residual form from being hazardous. The residual material is then stored and disposed of properly.

The invention relates to a system and device for desalination by liquid water jet compression, which is a phase-change desalination with a high-efficiency latent heat exchanger in which the pressure of the primary saturated vapor is increased until obtaining the secondary saturated vapor by injecting translational and rotational kinetic energy via pressurized water jets, so as to leave an unobstructed path through which the vapor flows at high speed in order to achieve a high flow rate and high efficiency.
