Embodiments of the invention provide systems and methods for water purification and desalination. The systems have a preheater, a degasser, multiple evaporation chambers with demisters, heat pipes, and a control system, wherein the control system permits continuous operation of the purification and desalination system without requiring user intervention or cleaning. The system is capable of recovering heat from each distillation stage, while removing, from a contaminated water sample, a plurality of contaminant types including: microbiological contaminants, radiological contaminants, metals, salts, volatile organics, and non-volatile organics.

This disclosure concerns a system and a method for removing dissolved solids from liquids. Specific implementations concern desalinating water. The system may comprise a blower, such as a thermal fan/compressor, configured to atomize a solid-bearing liquid to produce a hot, humid gas containing dissolved solids; a gas-solid separator configured to receive hot, humid gas containing entrained dissolved solids from the blower to separate the solids from the humid gas and to transmit the humid gas with solids removed through an exit port; a heater configured to heat the hot, humid gas received from the exit port of the gas-solid separator; and a condenser configured to receive heated humid gas from the heater and to condense solids-free liquid therefrom. The thermal fan/compressor may comprise a plurality of nozzles with outlets positioned adjacent atomization apertures across which a solid-bearing liquid flows and through which gas exiting the nozzles passes.

This method for painting a surface (S62) of a component (6) with a pattern includes at least the following steps consisting in applying a first coating product on at least a portion of the surface, automatically applying at least one portion of a mask (12) on a portion (Z62) of the surface, applying a second coating product and on the surface and removing the mask (12). Preferably, the mask (12) is at least partially automatically applied in the form of at least one layer (122, 124, 126) of non-atomized fluid, the layer being obtained by moving (A1) an applicator (16) delivering the non-atomized fluid along the portion (Z62) of the surface (S62) where the mask (12) is to be applied.

A MEG reclamation process includes the step of increasing above 2,000 ppm the divalent metal salts concentration of a rich (wet) MEG feed stream flowing into a precipitator. The increasing step includes routing a salts-saturated MEG slipstream from the flash separator it to the precipitator. The slipstream may be mixed with a fresh water feed stream, a portion of the rich MEG feed stream, or some combination of the two. The rich MEG feed stream also may be split into two streams, with a portion of the stream being heated and routed to the flash separator and the other portion being combined as above with the removed slipstream. The process can be performed on the slipstream after dilution and prior to entering the precipitator or after being loaded into the precipitator. Removal of the insoluble salts may be done in either a batch or continuous mode.

The invented system used in wet cooling tower, restore outlet fog of cooling tower into collection basin and consequently cooling water cycle. This invention consists of three main components; pump and its pertaining piping, waterfall and micron fog eliminator. In the first stage, the air containing fog is passed through a waterfall before exhausting. This action causes some portions of fog to condensate and fall down, remaining droplets of the fog grow and together with air cross the fog eliminator blades. Fog's droplets are entrapped between blades, leave the air, and restore to the tower. Therefore, humidity of exhausted air from tower will be effectively reduced.

Disclosed is an integrated liquid injection evaporation container, including a container body provided therein with a space for storing a liquid; a seal gasket configured to seal the container body from an upper end portion is provided on an upper portion of the container body, where the seal gasket is an electric material; a press cap configured to press the seal gasket tight on the container body is further provided; a first injection hole configured to inject a fluid is provided on an upper end of the container body; a second injection hole corresponding to the first injection hole is provided on the press cap. Use of the first injection hole, the second injection hole, and the seal gasket achieves the objectives of convenient liquid injection without contamination, and simple mechanical liquid injection.

A wastewater concentrator a liquid evaporator assembly, a gas-liquid separator, an exhaust assembly, and a flowback water concentrating system. The flowback water concentrating system includes a settling tank fluidly connected to the gas-liquid separator and a supernatant liquid concentration sensor for measuring a concentration of dissolved solids in the supernatant liquid in the settling tank.

A wastewater treatment system includes a circulating fluidized bed evaporator defining a longitudinal axis vertical with respect to gravity. The evaporator has a wastewater inlet to provide wastewater to the circulating fluidized bed evaporator. A heat inlet is axially below the wastewater inlet to provide heat to the circulating fluidized bed evaporator for evaporating the wastewater. An outlet is axially above the wastewater inlet and the heat inlet.
