A method for circulating hot air in a solar desalination system includes providing a desalination structure having an air flow path defined between an external surface layer and an internal surface layer. A return flow conduit provides an internal fluid flow path. Saline water is pumped through a center column in a direction from the base towards the peak. The saline water is delivered through a nozzle that extends through a sidewall of the center column to provide a mist within the desalination structure exterior of the center column. An air flow within the air flow path is heated to form a hot air supply. The mist is heated with the hot air supply to form an evaporated fluid. A diverted portion of the hot air supply is delivered into the return flow conduit and mixed with an ambient air to form and heat the air flow.

Drying the effluent from the trinitrotoluene (TNT) purification process, known as red water, is described that uses spray drying in an efficient, improved, and safe manner. The characteristics of the obtained powder, the use thereof, and a packaged product containing said powder are further described. The proposed technique provides the use of lower temperatures at liquid incineration (<300° C. compared to 1000° C.), and also the fact that the main target material is not broken down, thereby not generating toxic fumes, and enabling the dry powder to be used for other applications.

A wastewater processing method includes introducing wastewater into an upper region of a chamber. The chamber remains at substantially atmospheric pressure. A portion of the wastewater in the chamber is vaporized. Flame is introduced into the chamber and provides for the ignition of a volatile organic compound. The vaporized portion of the wastewater is vented to the atmosphere.

An evaporation system for spray evaporating undesired water comprising: a first pump, a container comprising a sump, a second pump, a spray manifold comprising a spray nozzle, a packing system disposed within the container, a third pump, and an air system comprising an air blower and an air preheater is disclosed. An outlet of a water inlet is connected to an inlet of the first pump. A first portion of a ceiling of the container is constituted by a demister element such that the first portion of the ceiling is entirely configured as an outlet for evaporated water. A second portion of the ceiling is adjacent to an upper edge of a wall of the container. An outlet of the first pump is connected to an inlet of the container. An inlet of a draw line is disposed in the sump; and an outlet of the draw line is connected to an inlet of the second pump. An outlet of the second pump is connected to an inlet of the spray manifold. The spray nozzle discharges water droplets onto the packing system. An inlet of the third pump is connected to an outlet of the sump. An outlet of the third pump is connected to a discharge outlet. The air system is disposed through the wall of the container; and the air system discharges air flow counter to and/or crossways to the water droplets from the spray nozzle. A method of using the evaporation system is also disclosed.
