Scarcity of potable water becomes a challenge: Desalination is a viable option

G.N. Tiwari

The basic needs for survival of human being on the planet are clean air, potable water and healthy food. The potable water is most second important need for human being. In present scenario, in addition to these basic needs, clean energy is also important. The influence of these basic needs on our life on the planet earth is immense. However, potable water on the planet earth including underground, surface and atmospheric moisture is less than 1%. Further, the potable water has been polluted badly in the past due to industrialization, fast growth in agriculture and population all over the world. So, the scarcity of potable water becomes a challenge today. To solve these problems, there are two methods of purifying the polluted underground and surface water, namely (i) conventional methods (reverse osmosis, flash distillation, membrane technology, etc.) which is very energy (fossil fuels) intensive, and (ii) solar distillation needs no energy/fossil fuels. In this scenario, passive and active solar distillation will play an important role to solve current problem of potable water.  Further, there is strong need to develop self-sustained active solar distillation systems if possible to meet the requirement of potable/distilled water. There is a lot of scope to carry out research in these areas...
