Multi-unit, distributive, regenerable, in situ desalination method

Cultivated field water is desalinated by a series of independent units that float on the water surface, taking up the saline water with a wick, evaporating the water from the wick in desalinating relation by concentrating incident solar radiation with a combination of a lenses and cooperating mirrors onto the upper end portion of the wick while the wick lower end portion is immersed in the field water, capturing the desalinated vapor resulting by condensing within the unit and returning the condensed, desalinated water to the field, and periodically renewing the wick by rinsing the salt from it at a cleaning station beyond the field.

Fluid evaporator for an open fluid reservoir

A reservoir evaporation system for evaporating fluid from an open reservoir of effluent containing a contaminant includes a fluid evaporator, an air pump, and an air supply conduit functionally connecting the fluid evaporator with the air pump. The fluid evaporator includes a vessel adapted to be positioned in an operative position partially submerged on the top surface of the effluent in the reservoir with a lower chamber submerged in the effluent and an upper chamber extending above the top surface of the effluent. In operation, air from the air pump mixes with the effluent inside the fluid evaporator and subsequently is discharged through exhaust openings. A fluid discharge pipe can also simultaneously discharge aerated effluent back down into the reservoir. Fluid is thereby separated from the effluent in the lower chamber by evaporation in a controlled manner that minimizes spread of contaminants to surrounding environments by wind.

Liquid purification with film heating

A purification system can provide for efficient heating of liquid via film heating, which, rather than heating a large volume of liquid, can heat a thin layer of liquid thus reducing the amount of energy required to evaporate the liquid. Film heating can enable evaporation of liquids using less energy than other methods. In addition, when liquids (e.g., seawater) having dissolved solids (e.g., salts) are heated, both the liquid and the solids must be heated. As evaporation occurs, the concentration of solids increases and more energy must be supplied to the liquid in order to cause evaporation. Because purification system can heat only a layer of liquid, less energy is required to heat the solids, which can allow for higher energy efficiencies in purifying liquids. These efficiencies can lead to decreased cost of potable water. Related apparatus, systems, techniques, and articles are also described.
