Answer: Defence Research and Development Organisation (DRDO)
Notes: Recently, the Defence Research and Development Organisation (DRDO) developed a high-pressure nanoporous multilayered polymeric membrane for seawater desalination. The project was carried out by Defence Materials Stores Research and Development Establishment (DMSRDE), Kanpur, under the Aatmanirbhar Bharat initiative. This membrane is made to suit the needs of the Indian Coast Guard (ICG), especially to resist chloride ion damage in salty seawater. It will be used on Offshore Patrol Vessels (OPVs) of the Coast Guard to ensure a self-reliant supply of freshwater onboard. Desalination means removing salts from seawater to make it usable for drinking or industry.
