Abstract:
A treatment process and a treatment system are provided for treating an aqueous saline solution. The treatment process comprises contacting an aqueous saline solution with an effective amount of a miscible organic solvent to precipitate dissolved salts and produce a mixture of precipitated solid salts and a liquid and then removing the precipitated solid salts from the liquid. The treatment process further comprises cooling the liquid to produce an organic phase comprising the miscible organic solvent and an aqueous phase comprising the miscible organic solvent and the dissolved salts and then removing the organic phase from the aqueous phase. The treatment process further comprises introducing the aqueous phase into a membrane device to remove the miscible organic solvent and the dissolved salts from the aqueous phase.

The second current collectors of a first of the plurality of capacitive electrode stacks may be connected to the first current collectors of a second of the plurality of capacitive electrode stacks.
Abstract:
The present invention relates to a freshwater separator employing a membrane distillation method, and a forward osmosis desalination system comprising the freshwater separator. More particularly, the present invention relates to a desalination system in which only a portion of a diluted draw solution is separated into gas and freshwater in a freshwater separator and the other portion of the diluted draw solution is fed directly into a forward osmosis separator, so that the efficiencies of the seawater separator and the desalination system comprising same are increased and the energy consumption is reduced.
Abstract:
Provided are a method and apparatus for producing potable water by post-processing (post-treating) desalined water obtained by desalination of seawater through distillation or reverse osmosis. The method includes a carbon dioxide absorption process (30) of excessively supplying carbon dioxide into the desalinated water to absorb the carbon dioxide, a remineralization process of passing the desalined water into which cai'bon dioxide is absorbed through a limestone filter (42) in which limestone is filled to form calcium ions and bicarbonate ions, and a cai'bon dioxide exhaust process (50) of supplying air into the desalinated water passed through the remineralization process to exhaust the carbon dioxide with the air to obtain the potable water. Therefore, a TDS concentration of the desaiinated water obtained through a distillation method or a reverse osmosis method can be effectively increased to produce potable water, alkalinity of the potable water can be increased to prevent corrosion of a water distribution system, and the potable water can be produced with a simplified apparatus and low cost.
Abstract:
There is provided a regenerative adsorption distillation system comprising a train of distillation effects in fluid communication with each other. The train of distillation effects comprises at least one intermediate effect between the first and last distillation effects of the train, each effect comprising a vessel and a condensing tube for flow of a fluid therein. The system further comprises a pair of adsorption-desorption beds in vapour communication with the last effect and at least one intermediate effect, wherein the beds contain an adsorbent that adsorbs vapour from the last effect and transmits desorbed vapour into at least one of the intermediate effect.

Abstract:
Device (300) for purifying water, comprising an elongated, hollow structure in turn comprising a first space (310), comprising a supply opening for water to be purified and a boiling device (311) for such water, arranged to heat the water to the boiling point using energy from focused sunlight which is supplied via a supply device (10) for sunlight via an optical fibre to a certain heating location in the first space; a condenser for condensing water vapour from the boiling device; and a conduit device (343) for water vapour, arranged to bring water vapour from the first space to the condenser. The invention is characterised in that a heat exchanger (333) is arranged to transfer thermal energy from either hot water vapour which has been boiled off in the boiling device or condensed water which is still warm and originates from such vapour, to water to be purified and which is to be introduced into the first space through the supply opening. The invention also relates to a method.
