Abstract: |
Distillation is one of many processes available for water purification, and sunlight is one of several forms of heat energy that can be used to power that process. Sunlight has the advantage of zero fuel cost. To dispel a common belief, it is not necessary to boil water to distil it. Simply elevating its temperature, short of boiling, will adequately increase the evaporation rate.
Solar distillation systems can be small or large. These solar energy distilling plants are relatively inexpensive, low-technology systems.
Solar distillation of potable water from saline (salty) water has been practiced for many years where fresh water is scare. In order to increase the output rate of the purified water, we use a vacuum pump, which is used to increase the efficiency. Vacuum pump is used to reduce the working pressure which result in the boiling of water at a lower temperature.
In this design we have incorporated a pump which is a simple vacuum pump to reduce air pressure inside the distillation chamber. We need to operate the pump to reduce the pressure to the minimum value and then leave it in the sun for distillation.
