    摘要: A groundwater remediation system includes a capillary media supported and positioned such that it is partially submerged into a groundwater source to be remediated. Groundwater is drawn into the submerged portion of the capillary media and further into the non-submerged portion of the capillary material via natural capillary action. As the water evaporates from the non-submerged portion of the capillary media, the dissolved solids within the water precipitate onto the media leaving the precipitated solids for reclamation or disposal and allowing the cleaned water vapor to disperse into the ambient air. In some embodiments, heat may be added to the media, water, or air to accelerate the evaporative process.

    摘要: A system and method for decontaminating a fluid and recovered vapor, particularly processing and recycling water used in an oil zone steam process, utilizing a vaporizer-desalination unit to separate a contaminated water flow into a contaminated disposal flow and a clean water vapor flow. The contaminated water flow is recovered after separation from a combined oil and water flow from an oil well. The clean water vapor flow is preferably passed through a steam generator to produce the steam used in the oil zone steam process. The steam is injected into the oil zone of a designated well and then extracted as the combined oil and water flow. Once primed with sufficient external water, the system and method is designed to operate continuously with minimal replenishment because of the water/vapor/steam cycle.

    摘要: Methods, systems, and techniques for desalinating a saltwater using a humidifier unit. The humidifier unit has a housing, which has a carrier gas inlet and a saltwater inlet. The humidifier unit also includes a packing, within the housing, having a surface with a critical surface tension of less than 25 mN/m according to the Zisman method. The packing is arranged to facilitate a saltwater that enters the housing through the saltwater inlet and a carrier gas that enters the housing through the carrier gas inlet to contact each other. The contact facilitates evaporation of the saltwater, which produces salt solids on at least a surface of the packing, a humidified gas and a concentrated brine.

    摘要: 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.

    摘要: A cold evaporation water purification system by through fractionated surfaces based on a physical phenomenon of liquids called adhesion principle. The liquid sticks to the contour of a solid surface, imitating its shape and thickness, this, by being rounded and thin, allows the thinning of the aqueous films, making them embrace the whole segment (contact surface) and in this way reducing enormously the energy used to carry out evaporation. The thin aqueous film will be efficiently distributed in 360 degrees of a fractionated system that is also in rotation, causing cold evaporation to be much more efficient with respect to commonly used methods. The cold evaporation water purification system by through fractionated surfaces comprises an evaporation mesh, a rotating element, a plastic tub, an air flow turbine and a condensing element.
