The present invention relates to water purification using solar energy. More specifically, systems and methods according to the present invention collect solar energy to heat non-potable water in a super-insulated structure. Compressed heated air is injected to evaporate water vapor out of brackish water, saltwater, or dirty water, thereby creating saturated air. The saturated air is drawn through a cooling tower and distilled water is precipitated. The systems and methods employ heat recovery and recycling processes to maximize energy efficiency.

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.

Systems and methods for disposing of produced water as steam released into the atmosphere. After wastewater is prepared for disposal by suitable filtering and/or treatment, it flows into a preheating tank where it is heated prior to disposal by liquid filled preheating coils extending from the heating tank which are heated by burner boxes. From the preheating tank, the preheated water flows into evaporation coils, where it is heated above boiling and released as steam. Water flowing into the tank passes adjacent the evaporation and preheating coils near the burner boxes. The preheating coils may contain antifreeze which can be circulated to prevent freezing of the preheat tank when not in use or to maintain the temperature of the preheat tank. The system may be moved with the preheat tank filled with preheated water to facilitate the use another location.

Selective scaling in water treatment systems in which desalination is performed is generally described. According to certain embodiments, the location of the formation of solid scale within a water treatment system is controlled by adjusting one or more system parameters, such as the temperature and/or flow velocity of a saline stream within the water treatment system.

A method is described herein, comprising vaporizing a glycol material by thermal contact with a heating medium to form a vaporized glycol stream, increasing a pressure of the vaporized glycol stream to form a pressurized glycol stream, and increasing a temperature of the heating medium by thermally contacting the heating medium with the pressurized glycol stream.

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.
