System for the purification of water by cold evaporation through fractionated surfaces

A cold evaporation water purification system using fractionated surfaces, comprising:

• an evaporation mesh configured to carry out a mass transfer, comprising a plurality of cells in a concentration between 2000 and 3000 cells per m2;
• a rotating element conformed by a cylinder with a shaft and two side caps, wherein said rotating element is configured to be coupled to the evaporation mesh on the cylinder;
• a plastic tub comprising a water mirror therein, which is configured to receive the rotating element and evaporation mesh coupled thereto, so that a part is submerged within the water mirror thus forming an aerobic area and an anaerobic area in the rotating element, so that when the element rotates water is hauled from an anaerobic area to an aerobic area for purification;
• wherein when the rotating element and the evaporation mesh are submerged and then emerged from the water mirror, a set of elongations of aqueous components of the water is generated in each of the cells of the mesh, coating a space of the cell, forming a thin film, decreasing an evaporation coefficient of the water, and causing an elongation of the aqueous components along a geometry of the cell;
• and
• further including an air flow turbine generating an air flow with a speed that has energy necessary to break surface tension of the water and the thin film formed, fractionating said thin film and generating cold vapor wherein solids suspended in the water are decanted in the plastic tub, and to transport said generated cold vapor;
• and
• a condensation element located adjacent to the tub and the rotating element, the condensation element being a fin and tube condenser, with a primary and secondary area, wherein a cooling water circulates with a Delta T of between 15 and 30° C., which is configured to receive and condense the cold vapor transported by the air flow, and thus recover pure water;
• wherein the plurality of the cells is housed in the rotating element in a form of a spiral.
