The second seawater reverse osmosis (RO) plant to provide drinking water for the city of Chennai, India, was commissioned last month by the state’s chief minister, Selvi J Jayalalithaa.
Located 50 km south of Chennai, it will have a capacity of 100,000 m³/d and was constructed by VA Tech Wabag for the Chennai Metropolitan Water Supply & Sewage Board.
Although the facility is reported to only be currently producing at 50% capacity, this is expected to increase up to 100% in the coming weeks. It will supply water to residents of the southern suburbs of Chennai in Velachery, Pallipattu, Thiruvanmiyur and the localities along the IT corridor.
Pre-treatment technology will be supplied by Amiad Water Services and Seaguard ultrafiltration from Pentair X-Flow. The RO membranes are from Hydranautics/Nitto Denko and energy recovery features pressure exchangers from Energy Recovery Inc.
