Rose, only way is to extract water from the salts through solar evaporation. Unfortunately, this is not cheap. I have installed systems using pervaporation using solar thermal heat and hydrophobic membranes that work on a very simple principle of vapor pressure differential across a membrane that only allows vapor to pass, no water. Another way that has been accomplished is through "pouches" of Forward Osmosis. Concentrated sugar solutions are diluted through the membranes via the osmotic pressure created by the sugar solution. Unfortunately, you get a "gatorade" as a drink, not a glass of pure water. It would be nice to discuss how much money, what capacity, etc.

Dear Juzer, thanks for responding. We are looking for something cheap that the villagers can afford. This is a common problem in a number of villages being served by drilled boreholes. How much are you talking about on the higher side?
