A device for monitoring evaporation capacity of a water surface evaporator in a process includes a water surface evaporator and a rain collector, the rain collector and the water surface evaporator having a same size of orifice area, height, and contour profile of a monitoring device. One side of the water surface evaporator is connected with a first measuring well through a pipeline, and another side of the water surface evaporator is connected with a first electromagnetic flowmeter, a water supplementing electromagnetic valve and an overflow electromagnetic valve through a water pipe. The water supplementing electromagnetic valve is connected with a water supplementing barrel through a water supplementing pipe. A water collecting barrel is installed below the special rain collector. A second magnetostrictive water level meter, a starting drainage switch and a stopping drainage switch are installed in the second measuring well.

A method and system of providing ultrapure water for semiconductor fabrication operations is provided. The water is treated by utilizing a free radical scavenging system. The free radical scavenging system can utilize actinic radiation with a free radical precursor compound, such as ammonium persulfate. The ultrapure water may be further treated by utilizing ion exchange media and degasification apparatus. A control system can be utilized to regulate a continuously variable intensity of the actinic radiation.

Disclosed is a system and method for cooperatively treating water and gas to reduce pollutants and carbon emission. The system includes a flue gas pre-treatment unit, a wastewater pre-treatment unit, a gas-water cooperative cleaning unit, a remaining water treatment unit, and a circulating cooling evaporation unit.

A method for obtaining pure drinking water from dewatered biological products is described. The process is carried out in a hermetic dewatering chamber isolated from the ambient atmosphere and in parallel with a process during which dried products are placed on drying trays. All the process parameters, such as temperature, humidity, and appropriate pressure inside the chamber, are controlled. The vapor generated during the product dewatering process, released from the products, is continuously removed from the dewatering chamber through the upper opening, exits through the outflow channel, and enters through the condenser. The process of obtaining clean drinking water is carried out outside the chamber and is conducted in several stages: vapor passes through disinfectant grids, vapor flows to a condenser cooled with ice water, and the vapor condenses on densely arranged lamellas. The condensate is then pumped to a discharge tub.

A method of producing water supersaturated with a gas includes drawing water from a water supply; filtering the water; purifying the water; disinfecting the water and neutralizing remaining biocontaminants; filtering the water to remove the neutralized biocontaminants; mineralizing the water; supersaturating the water with nanobubbles of a gas; and storing the water. A system for producing the supersaturated water includes a filter; a purification unit connected to an outlet of the filter; an ultraviolet treatment reservoir connected to an outlet of the purification unit; a second filter connected to an outlet of the UV treatment reservoir; a minerals addition unit connected to an outlet of the second filter; and a nanobubble generator connected to an outlet of the minerals addition unit. The water can be economically supersaturated at levels higher than 120%.

Multi-chamber Compressor (6, 206, 506) of Mechanical Vapor re-Compression (MVC) and water treatment methods, the compressor bearing independent compression chambers of positive displacement, for heat-pumps, of two main variants: a) reciprocating-rotary motion (6, 206) wherein the compression chambers (7V) are radially arranged cylindrical sectors based on concentric circular sectors of the same angle, with, pistons of radially arranged vanes (20, 220) of respective surface and with the plane of the vanes passing through the axis of the common rotor (14) and the shaft (16) and b) reciprocating-linear motion (506) wherein the compression chambers (52v) are in series arranged cylinders with pistons/vanes (50v) of corresponding circular surfaces and with the plane of the vanes perpendicular to the common shaft (51). In both cases, the shaft (16, 51) and the motor are common to all the vanes (20v, 50v), which follow identical strokes. The surfaces of the vanes (20v, 50v), as well as of the compression chambers (7V, 52v), differ from each other, since each compression chamber (7V, 52v) has its own and independent pair of evaporation (ev, dv, Lv, by) and heat-exchanger chambers/areas (Cv/eCv, 32v/33v, 132v, 54v/53v), said compression chamber exclusively sucks from, compresses and discharges to, and the fluids/vapors being dispensed, are under different thermodynamic state conditions. The stages are independent from each other, the medium-vapor providing the energy of evaporation is produced in the stage itself, and flow rate and compression ratio CR are independently controlled and adjusted in each stage.
