APPARATUS AND PROCESS FOR DESALINATION OF BRACKISH WATER USING PRESSURE RETARDED OSMOSIS

摘要

Water from underground and other sources is 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. Pressure retarded osmosis process using an apparatus is also used to further purify water. 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.
