TIME FOR INDIAN VILLAGES TO CONVERT SALTY WATER TO POTABLE WATER THROUGH SOLAR TECHNOLOGY: It must be known to all that there is more salty ground water than fresh, drinkable ground water around the world. In fact estimation says, 60 % of India is dominated by salty water and much of that area is not served by an electric grid that could run conventional reverse-osmosis desalination plants. Lack of drinking water is basically a problem of rural India. Hence having an aim to facilitate potable drinking water to the village mass researcher of Massachusetts Institute of Technology (MIT) has revealed that Indian villages could use Solar Power technology to turn salty water into potable water through a Solar powered desalination technology called electro-dialysis which could provide enough clean, palatable drinking water to the villagers. The factors that point to the choice of electro-dialysis in India include both relatively low levels of salinity, ranging from 500 to 3,000 milligrams per liter, compared with seawater at about 35,000 mg/L; as well as the regions lack of electrical power. Such moderately salty water is not directly toxic, but it can have long-term effects on health, and its unpleasant taste can cause people to turn to other, dirtier water sources. While many homes in India currently use individual, home-based filtration systems to treat their water, however, MIT graduate student Natasha Wright and Amos Winter concluded that village-scale systems would be more effective, both because fewer people would be left out of access to clean water, and because home-based systems are much harder to monitor to ensure effective water treatment. Researchers plan to put together a working prototype for field evaluations in India in January. While this approach was initially conceived for village-scale, self-contained systems, researchers said that the same technology could also be useful for applications such as disaster relief, and for military use in remote locations.
