    摘要： The present invention relates to treatment systems for polluted and sea water by recrystallization and may be used in everyday life, the food industry, in the catering business and healthcare.
    The system comprises at least two heat-exchange devices that contain chambers for water freezing and ice melting, cooling and heating components, a water circulation loop, a refrigerant circulation loop connected with cooling and heating components able to alternate water freezing and ice melting in the chambers of heat-exchange devices and to transfer the heat generated in the water freezing chamber into the ice melting chamber, a control and monitoring tool. Heat-exchange devices are arranged as a cascade one under another and comprise outer and inner housings as well as a cylindrical baffle, which are coaxial relatively to each other and form an annular cavity between their walls; an air supply manifold, cooling and heating components, a heating component fastened at the top of the inner housing and at least one drain nozzle. The outer housing is cylindrical or truncated cone-shaped with a cone angle directed upwards. The outer housing has an additional inner wall, the shape and height of which meet the outer housing while cooling and heating components are located between the said walls. The baffle and the housing internal wall may be connected to an electrical current source.
    The combination of sufficiently large performance and high quality of water treatment in the system allows it to use for treating initial water with a wide range of with organic and inorganic contaminants.

    摘要： A system for processing saltwater or brackish water while recovering energy otherwise wasted in electricity generation by a natural gas generator or turbine. Heat in the generator exhaust is used to directly heat and process the water in the saltwater or brackish water into high quality steam, separating the majority of salt and contaminants from the water, and leaving potable water that can be permitted and released to the environment or sold for agricultural or industrial use such as oilfield activities. The system also captures and liquefies CO2 in the generator exhaust.

    摘要： Systems and methods of performing temperature swing solvent extraction (TSSE) descaling of produced water and desalination of high-salinity brines, e.g., those having a total dissolved solids (TDS) greater than about 250,000 ppm are capable of producing descaled water products including less than about 5% weight percent TDS. The brine/produced water feedstreams and combined with a solvent having temperature-dependent water solubility at a temperature TL. Water is extracted from the feedstream into the solvent to form a water-in-solvent extract component and a raffinate component, from which a solid phase can be precipitated as more water is portioned in the solvent and basicity increases. Heating of the water-in-solvent extract component reduces the solubility of the water therein, producing a biphasic mixture of dewatered solvent and descaled water that can be separated. Because these systems and methods do not require a phase change of water, these products are achieved with significantly higher energy efficiencies when compared to evaporation-based thermal methods.
