Apparatus for purifying a liquid, which comprises a container housing multiple closed cells, each delimited by an anionic membrane and by a cationic membrane, and multiple open cells, susceptible of being traversed by a liquid to be treated and each interposed between two adjacent closed cells. The apparatus also comprises two electrodes which are supplied with supply voltages with reversed polarities in order to push the ionized particles of the liquid into the closed cells during an operating phase, and in order to bring the ionized particles back into the open cells during a regeneration phase. The apparatus also comprises a polymer substance having functional groups with non-zero electric charge, which is contained inside the closed cells in order to create chemical bonds with the ionized particles of the liquid that enter therein.

A desalination system includes a watertight tank built into a barge to house reverse-osmosis tubes and flooded with cooling water or fluid a closed-loop water or a fluid circulation system that circulates water or fluid inside the watertight tank to cool the reverse-osmosis tubes and transfer the heat to a seawater radiator mounted on the exterior of the barge to cool the cooling water or fluid; a reverse-osmosis system consisting of a seawater feed pump sucking in seawater through wedge wire screens attached to an inlet or inlets in the hull of the barge, and pumping that water into a plurality of reverse-osmosis tubes housed within the watertight tank and configured to process the seawater passing through the reverse-osmosis membrane to freshwater water stream and a brine water stream; and a high-density polyethylene (HDPE) pipeline.

According to one embodiment, a method, computer system, and computer program product for manufacturing a semi-permeable membrane for purifying a fluid through reverse osmosis is provided. The present invention may include calculating a shear stress exerted by the simulated fluid on semi-permeable membrane configurations; generating a membrane design for the semi-permeable membrane based on the modeling, wherein the membrane design comprises a material selected based on the calculated shear stress; and manufacturing a semi-permeable membrane of the selected material using a 3D printer, based on the membrane design.

Embodiments of an apparatus and method for the removal of moisture or liquid from a moisture-containing media include an evaporative layer, a containment structure with an internal atmosphere at least partially separated from an external atmosphere, a CPU, an energy source, a tunable output element, a wicking layer and an input element operably connected to the CPU and/or energy source. A method includes collecting a moisture-containing media in a containment structure; removing moisture or liquid from the media using an evaporative layer; adjusting a tunable element based on an evaporative condition; and increasing a rate of moisture or liquid evaporation from the media and/or the evaporative layer. An apparatus includes an evaporative layer configured to contain a moisture-containing media; an air inlet; and a containment structure mounted on a mobile vehicle, wherein the air inlet directs vehicle motion generated air adjacent to or impinging with an evaporative layer.
