This disclosure concerns a system and a method for removing dissolved solids from liquids. Specific implementations concern desalinating water. The system may comprise a blower, such as a thermal fan/compressor, configured to atomize a solid-bearing liquid to produce a hot, humid gas containing dissolved solids; a gas-solid separator configured to receive hot, humid gas containing entrained dissolved solids from the blower to separate the solids from the humid gas and to transmit the humid gas with solids removed through an exit port; a heater configured to heat the hot, humid gas received from the exit port of the gas-solid separator; and a condenser configured to receive heated humid gas from the heater and to condense solids-free liquid therefrom. The thermal fan/compressor may comprise a plurality of nozzles with outlets positioned adjacent atomization apertures across which a solid-bearing liquid flows and through which gas exiting the nozzles passes.

A system for desalination of salt water using solar energy. The system includes an inner channel for flow of salt water there through, the inner channel having a cover thereover that is water vapor impermeable yet UV transparent or transmissive. A collection channel for collecting clean water extends along the inner channel. By having the inlet of salt water to the inner channel elevated in relation to the outlet of salt water from the inner channel, the salt water flow naturally through the channel. A solar-powered pump can be used to provide the salt water to the inlet.

The hydrogen-powered desalination plant is a multi-stage flash desalination system using hydrogen fuel to power the top brine heater of the plant. The hydrogen-powered desalination plant includes a plurality of flash distillation stages, which each include a flash chamber and a condenser. The top brine heater in the hydrogen-powered desalination plant is powered by the carbon-free combustion of hydrogen gas with oxygen gas. The combustion of the hydrogen gas with the oxygen gas creates a flame, which is used directly to generate steam from atomized seawater, any seawater not converted to steam being collected as preheated brine and passed to the multi-stage flash desalination system for successive stages of flash distillation. Preferably, the flame is generated as a vortex.

A desalination system includes a water tank, a water-repellent particle layer located at a lower portion of the tank and composed of water-repellent particles, and a devolatilizing layer located below the water-repellent particle layer. Liquid is introduced to the tank, the introduced liquid is heated to be evaporated into water vapor, and the water vapor passes through the water-repellent particle layer and is liquefied at the devolatilizing layer, so that fresh water is obtained from the liquid. The desalination system further includes a liquid level controller for determining a level of the liquid introduced to the tank in accordance with information on relationship between information corresponding to an amount of the liquid introduced to the tank and a surface level of the liquid in the tank, and an introduced amount controller for adjusting the amount of the liquid introduced to the tank in accordance with the determined liquid surface level.

A device for purifying water by solar power is described. The device has bottom and top sections, each being half-cylinders contacting one another along a flat edge to provide an elongated cylinder. The bottom section has an evacuated area with an optically transparent bottom surface that light can pass through to heat a liquid tray in the top section. A side-gutter directs water that condenses on an interior surface of the top section to an output port for collection.
