The final solution is a vacuum evaporation system. Vacuum evaporation is the process of causing the pressure in a liquid-filled container to be reduced below the vapor pressure of the liquid, causing the liquid to evaporate at a lower temperature than normal.
Although the process can be applied to any type of liquid at any vapor pressure, it is generally used to describe the boiling of water by lowering the container’s internal pressure below standard atmospheric pressure and causing the water to boil at room temperature.
Our prototype consists of a hermetically sealed chamber that will store the water to be treated. In the following image, you can see a schematic of how our prototype works.
On the right side enter the liquid waste to be treated. When the chamber is full of liquid, the vacuum pump located on the left side is activated and has the effect of removing all air from inside the chamber. Reaching the pressure of -1 bar the liquid will start to evaporate thus giving the residue separation.
This method is not innovative, but its application in this type of solution. We believe that our solution can also be applied to other needs, for example, water desalination in countries with poor access to clean water.
