A desalination device includes a sealed desalination chamber with two compartments, an evaporator space that contains saline water, and a condenser space that contains fresh water, a saline water distribution mechanism that directs the saline water into the evaporator space, a vapor compressor that directs a stream of pressurized freshwater vapor into the condenser space, and an integrated regenerative boundary between the evaporator space and the condenser space that has two sides, an evaporation surface and a condensation surface, enabling the pressurized freshwater vapor to condense on the condensation surface to generate freshwater, and where the latent heat of the condensation process transfers across the integrated regenerative boundary into the evaporator space and evaporates a portion of the saline water to produce freshwater vapor.

A solar distillation system includes at least one solar panel to reflect sunlight, and a distillation tube adjacent the at least one solar panel. The distillation tube is to receive brine to be processed into fresh water. The brine is to flow through the distillation tube and is heated by the reflected sunlight. A first supplemental distillation unit is connected to a first end of the distillation tube and has a curved surface perpendicular to the distillation tube to receive the reflected sunlight. A second supplemental distillation unit is connected to a second end of the distillation tube and has a curved surface perpendicular to the distillation tube to receive the reflected sunlight. The first and second supplemental distillation units each include sprayers to spray brine onto the respective curved surfaces to be further processed into fresh water.

The invention is a high-salt waste water air powered low temperature evaporating device and method of use. A tray is mounted on a lifting platform; an air inlet and a water inlet are on the tray. Air distributing pipes are arranged at the center of the nested column tubes (33). A groove (4) is installed at the top of the tray, and mounting points are accompanied by multiple nested column tubes (33). The nested column tubes (33) are connected with the air inlet. An atomizer is arranged inside the air distributing pipes; and the atomizer is connected with the water distributing pipes. Using air power evaporates concentrated waste water multiple times so that the salt in the wastewater reaches saturated concentration, and therefore, the wastewater temperature is reduced, salt is crystallized and separated out, liquid is continuously evaporated, and the wastewater can be completely treated.

Certain embodiments may provide a method for controlling a desalination system. The method may include performing a desalination procedure with salt-water in a desalination compartment of the desalination system. The method may also include extracting brine and freshwater from the desalination procedure. The method may further include directing the brine to a brine treatment compartment of the desalination system, and the freshwater to a firewater container. In addition, the method may include performing a brine treatment procedure in the brine treatment compartment. Further, the method may include collecting concentrated brine from the brine treatment compartment.

The present disclosure is drawn to systems and methods of treating or utilizing water, including water for cooling applications, using evaporation panels, evaporation panel systems, and evaporation panel assemblies. For example, the system can include an evaporation panel fluidly coupable to a body of water. The system can also include a fluid directing assembly to recirculate water from the body of water to an upper portion of the evaporation panel, wherein as water cascades down the evaporation panel and evaporates, evaporative cooling occurs. The system can further include a fan directed at the evaporation panel to push airflow through a plurality of open spaces of the evaporation panel, thereby generating humidified cooled airflow therefrom.

A hybrid process and system for separating water from an inlet brine solution is disclosed. The hybrid process couples at least two different separation processes/systems. The inlet brine solution is fed into a first separation process, which produces a water distillate and a brine concentrate. The brine concentrate from the first separation process is then fed into the second separation process to further recover additional water. The excess heat from the second separation process is supplied to the first separation process.

A floatable interfacial solar-driven evaporation structure includes a water impervious thermal insulation layer adapted to float on a body of water, a porous absorber layer on the water impervious thermal insulation layer, and an interlocked non-woven cotton fiber layer having a portion thereof between the water impervious insulation layer and the porous absorber layer and one or more additional portions configured to extend to the body of water to act as a capillary-driven pump to transport water from the body of water to the porous absorber layer. An ultra-black photothermal paint covers the exposed upper surface of the porous absorber layer to convert solar radiation impinging on the ultra-black photothermal paint into heat for use in generating water vapor from water in the porous absorber layer.
