Water to be desalinated or otherwise purified is enriched by having hydrate-forming substance dissolved into it, without causing hydrate to form. Hydrate kernels are brought into contact with the enriched water to be treated, and the hydrate kernels grow outwardly into the water to be treated by incorporating dissolved molecules of the hydrate-forming substance and water from the water to be treated. Thus, substantially solid, generally spherical hydrate masses, which are preferred for hydrate-based desalination or purification, can be formed. Hydrate-forming substances can be dissolved into the water to be treated under conditions not conducive to formation of hydrate, such that hydrate does not form, using vigorous means. Hydrate-forming substance is also preferably dissolved into the water to be treated under conditions suitable for hydrate to form, but without causing hydrate to form, e.g., by being infused into the water to be treated using infusion membranes.

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.
