The present invention relates to an effluent liquid evaporator (100) to treat wastewater by increasing the evaporation rate with easy and automatic cleaning in an economical manner. The effluent liquid evaporator (100) comprises a pan module (101), a fan module (102), a set of sensors (103) and an injection unit (104). The injection unit (104) is configured to inject a controlled amount of effluent in said pan module (101). The pan module (101) include a plurality of stack of pans (105) to retains the desired amount of effluent to be heated via solar energy which results in evaporation of the effluent. The fan module (102) provides a direct and balanced airflow and facilitates rapid evaporation leaving behind a residue. The set of sensors (103) are configured to perform closing and opening operation on a set of vents for mixing fresh air with a humid air for increasing an evaporation rate of the pre-defined amount of effluent.

Techniques are described herein for using a high-pressure reactor to separate clean water from dirty water without filtration and to extract and concentrate contaminants from dirty water for use as a fuel. In particular, techniques and systems are described for separating water from hydrocarbon contaminates, other BTU-laden compounds, and dissolved minerals, while also boiling water and condensing the resulting steam into distilled water. In addition, system in which the described techniques are performed can be used as a high-pressure pump for moving the separated hydrocarbon contaminates forward into other processes, such as a high-pressure reactor or incinerator.

The present disclosure relates to nuclear chemical, particularly radiochemical, technologies at different stages of the nuclear fuel cycle, such as the production of purified nuclear materials (uranium, zirconium) or the reprocessing of spent nuclear fuel from nuclear power stations, in which extraction processes and operations for purifying nuclear materials are used. An example method, which includes the partial decomposition of nitric acid during continuous evaporation while a solution containing a reducing agent is fed into the bottom part of an evaporator having a circulating bottoms solution, consists in that the process is carried out such that the solution is kept in the bottom part of the evaporator for more than 2 hours under the addition of an aqueous solution of formaldehyde and formic acid (hereinafter the mixture) or a solution of formic acid after the process has been started using the mixture.

An evaporator is provided for evaporating water from an ambient body of water having a water surface. The evaporator includes a housing that has a proximal end proximate to the water surface, a distal end distal to the water surface, and a housing air flow channel directed toward the water surface. The housing is disposed on a support, such as a float assembly, that positions the housing above the water surface. The evaporator also includes an air flow induction device, preferably an impeller, disposed to direct an air flow stream from the distal end toward the proximal end through the housing air flow channel and toward the water surface so that the air contacts the water. The impeller preferably is made of a fiberglass material. The support preferably includes at least one float assembly air flow channel that receives the air flow stream from the housing and directs it outwardly from the evaporator. Water injection devices such as spray nozzles or atomizing nozzles preferably are disposed in the float assembly channel or channels to inject the water into the air flow stream.
