NTPC-NETRA optimises water conservation with effluent recycling treatment plant at Gandhar

By OEM Update Editorial September 12, 2018 3:09 pm IST

NTPC, India’s power generating company, is fully aligned for conserving water for sustainable ecological balance. NETRA (NTPC Energy Technology Research Alliance) proposed Effluent Recycling Treatment plant to achieve zero liquid discharge at NTPC’s Jhanor – Gandhar station to optimise water costs and minimise environmental footprint.

The recycled and reuse of treated effluents is profitable in the ever deteriorating environment of water scarcity. At present, only one stream of the station has been successfully commissioned and the next stream will be commissioned by 7th September 2018. At full load operation, NTPC Jhanor – Gandhar (657.39 MW) generates effluent of 4,500 M3 per day. The new recycling treatment has integrated high rate solid contact clarification, submerged Ultra filtration and RO modules technologies to give 125 M3/Hr high quality water. The produced water will be used for Demineral (DM) water production or directly in Cooling Water (CW) make-up in the power station.
