An apparatus, system and method to remove purified vapor from a contaminated fluid using energy. The apparatus comprises an inlet wherein contaminated fluid flows in the apparatus through the inlet; at least two outlets wherein a first outlet exits purified vapor and a second outlet wherein contaminated fluid with a portion removed as purified vapor exits the apparatus; an energy source that causes the contaminated fluid to heat to a temperature wherein at least a portion of the contaminated fluid is converted to purified vapor; at least two different flow paths from at least one inlet to the first outlet and second outlet, the first and second flow paths flow through at least a portion of the apparatus.

A wastewater management system includes a series of water treatment modules to treat wastewater and produce reusable and/or potable water and other beneficial byproducts of the wastewater treatment process. A pretreatment module, a filtration module, an evaporator module, an odor control module, a UV-light module, an autoclave module, a sonolysis module, an ozone module and a chlorination module are combined in multiple combinations along with holding tanks, condensers, flash tanks and other components to address water purification and reclamation needs based upon specific wastewater conditions. The system captures condensate from AC systems and rainwater from rainwater gutter systems processes the water to produce reusable and/or potable water with or without re-mineralization. Any CO.sub.2 produced by the water treatment system is captured and processed using naturally-occurring flora. The wastewater treatment system includes multiple closed-loop subsystems to minimize energy usage and maximize water purification and reclamation for reuse.

A hot water and distillation apparatus configured to simultaneously produce distilled water and hot water is disclosed. The hot water and distillation apparatus comprises a hot water tank, a condensation and evaporation chamber, an (feed water) evaporation tray provided in the condensation and evaporation chamber, a heat source thermally connected to the evaporation tray. The hot water and distillation apparatus is configured to condensate evaporated feed water from the evaporation tray by means of heat exchange between the hot water tank and a condensation surface. The condensation surface is provided at the outside surface of the hot water tank. The heat source is thermally connected to the evaporation tray. The hot water and distillation apparatus comprises a distillate collection member configured to collect distillate. The hot water tank, the evaporation tray and the distillate collection member are provided in the condensation and evaporation chamber.

A multi-effect system and a multi-effect method for desalination are provided. The method comprises flowing saline water over a thermally conductive plate of a first evaporation chamber; heating the thermally conductive plate to evaporate the saline water, resulting in vapor; removing the vapor from the first evaporation chamber; compressing, using a compressor, the vapor, thereby creating compressed vapor; pumping the compressed vapor into a first condensation chamber; condensing the compressed vapor in the first condensation chamber, resulting in fresh water. The method further comprises heating, by heat released by the condensing of the compressed vapor, a second thermally conductive plate forming a top of the first condensation chamber and a bottom surface of a next evaporation chamber in a next desalination chamber in the vertical stack of desalination chambers.

Processes and systems suitable for purifying or otherwise treating liquids to remove contaminants therein, including but not limited to contaminated water, to permit reclaiming, recycling, and reuse of the liquids. Such a process and system entails the use of a cascading distillation system that evaporates a liquid from the feedstock and then condenses and collects a more purified form of the liquid. The cascading distillation system can be operated to selectively process the feedstock through any of a series of vessels at which different amounts and/or contaminants may be removed from the feedstock.

A process for treating waste fluid generated during a petrochemical process. The process comprises: subjecting at least one first water-based wastewater stream to at least one freeze concentration stage so as to produce a third clean water stream and a fourth concentrated water-based wastewater stream, subjecting at least one second organic fluid-based waste fluid stream to at least one separation stage so as to produce a fifth purified product stream and a sixth concentrated organic fluid-based waste fluid stream, forwarding the fourth concentrated water-based wastewater stream and the sixth concentrated organic fluid-based waste fluid stream to an incinerator, and incinerating the streams in the incinerator. The process is controlled such that incineration of the sixth concentrated organic fluid-based waste fluid stream generates at least 70% of an energy necessary to incinerate the fourth concentrated water-based wastewater stream.

A sewage treatment machine comprising: a closed container inside which the liquid to be treated is brought to boil; a vacuum-generating apparatus, which is adapted to maintain the inside of the closed container at a given pressure having a value lower than the environmental/external pressure; a heat-pump assembly which is associated to the closed container so as to be able to transfer heat to the liquid present on the bottom of the closed container, thus to bring said liquid to boil, and simultaneously remove heat from the vapours that reach the top of the closed container, thus to condense the vapour and obtain a distilled liquid, and which contains a refrigerant fluid comprising one or more gases of the family of the hydrofluoroolefins in a percentage greater than 3%.

Drying the effluent from the trinitrotoluene (TNT) purification process, known as red water, is described that uses spray drying in an efficient, improved, and safe manner. The characteristics of the obtained powder, the use thereof, and a packaged product containing said powder are further described. The proposed technique provides the use of lower temperatures at liquid incineration (<300° C. compared to 1000° C.), and also the fact that the main target material is not broken down, thereby not generating toxic fumes, and enabling the dry powder to be used for other applications.

A membrane for water collection may include a sheet having a top surface and a bottom surface, and a plurality of conical structures disposed on the top surface of the sheet, the conical structures comprising a hydrogel material. Each conical structure of the plurality of conical structures may have a height of 1 mm to 50 mm, wherein height is measured from the top surface of the sheet to an apex of a conical structure. Each conical structure of the plurality of conical structures may have an apex angle of 10 to 60 degrees.

A wastewater processing method includes introducing wastewater into an upper region of a chamber. The chamber remains at substantially atmospheric pressure. A portion of the wastewater in the chamber is vaporized. Flame is introduced into the chamber and provides for the ignition of a volatile organic compound. The vaporized portion of the wastewater is vented to the atmosphere.
