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 water vapor distillation system. The system includes a water vapor distillation device configured to receive a volume of source water from a fluid source and produce distillate, the device comprising: a concentrate flow path comprising a concentrate output; a distillate flow path comprising a distillate output; at least one source proportioning valve; a first heat exchanger comprising at least a portion of the distillate flow path; a second heat exchanger including at least a portion of the concentrate flow path, wherein the first heat exchanger and the second heat exchanger in fluid flow communication with the fluid source; a distillate sensor assembly in communication with the distillate flow path and located downstream the first heat exchanger, the distillate sensor assembly configured to generate a distillate temperature measurement; and a controller configured to control the source proportioning valves, the controller configured to: receive the distillate temperature measurement; determine the difference between a first target temperature and the distillate temperature measurement; and split the source water from the fluid source between the first heat exchanger and the second heat exchanger based on the difference between the first target temperature and the distillate temperature measurement.

A process for treating a fluid includes: a step of introducing fluid to treat into a chamber of a dryer, a step of drying the fluid in the chamber including a first phase during which a weight of the chamber reduces and when the weight of the chamber reaches a lower threshold or a rate of variation of the weight of the chamber is less than a first predefined value, the drying step includes a step of complementary filling of the chamber until the weight of the chamber reaches an upper threshold and a second phase during which the weight of the chamber decreases and when the rate of variation of the weight is less than a second predefined value, the process includes a step of extracting a solid residue in powder form. The invention also concerns an installation for implementing the process.

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%.

Seawater desalination equipment includes a gas generation unit for generating gas from seawater by evaporating the seawater, a condensation unit for receiving and condensing the gas to generate freshwater, a cooling unit, a gas storage unit connected to the condensation unit and storing gas that has passed through the condensation unit, a vacuum pump, and a control unit for operating the vacuum pump that is configured to discharge the gas stored in the gas storage unit to an outside area when an internal gas pressure difference between the condensation unit and the gas storage unit is within a predetermined range. The condensation unit includes a condensation pipe having a zigzag shape and through which the gas passes. The cooling unit supplies the seawater to the outer surface of the condensation pipe to lower a temperature of the condensation pipe by evaporating the seawater.
