Ion Exchange’s SWRO plant

Ion Exchange (India) Ltd was awarded a prestigious र 126 crore contract to set up a Sea Water Reverse Osmosis (SWRO) plant for NTPC-Tamil Nadu Energy Company Ltd (NTECL), a joint venture between public sector firm National Thermal Power Corporation (NTPC) and Tamil Nadu Electricity Board (TNEB).

The 3x275m3/h SWRO plant for the 3x500MW thermal power plant at Vallur near Chennai will treat processed sea water to give demineralised water for use in the boiler drum for steam generation. Its key features include salt rejection ranging from 90-98% and product recovery ranging from 50-80% based on feed water composition. A small part of the reverse osmosis water will also be used as drinking water.
