Abstract: Water from underground and other sources of water are brackish and not suitable for human consumption. Naturally present dissolved chemicals in water make it brackish. The precipitants and dissolved chemicals need to be separated from water to make it consumable. A combination of aeration systems, filtration systems, crystallizers and hydrophobic membrane carrying filter are used to desalinate the brackish water. Solar energy and ceramic filters are used as add on to existing technology. Various heat exchange apparatus are used for energy conservation and efficient processing of water in a feasible way. The disclosure enables to purify water and provide a useful technology to eradicate water scarcity.
