DRDO Successfully Tests Indigenous High-pressure Seawater Desalination Technology

ENA Sectors 2025-05-16 15:38:38 New Delhi, May 16 (KNN) The Defence Research & Development Organisation (DRDO) has successfully developed a nanoporous multilayered polymeric membrane for high-pressure seawater desalination. The development was completed in a notably efficient timeframe of eight months by the Defence Materials Stores and Research & Development Establishment (DMSRDE), DRDOs specialised laboratory in Kanpur, marking a significant advancement in indigenous maritime technology. This technological breakthrough addresses a critical operational challenge faced by the Indian Coast Guard (ICG) regarding the stability of desalination systems when exposed to chloride ions present in saline water. The membrane technology was specifically engineered to meet the operational requirements of ICG vessels, enhancing their self-sufficiency during extended maritime deployments. Initial technical trials were conducted collaboratively by DMSRDE and ICG personnel using the existing desalination infrastructure aboard an ICG Offshore Patrolling Vessel (OPV). The preliminary safety and performance evaluations yielded entirely satisfactory results. The ICG will grant final operational clearance following an extended 500-hour operational testing period to ensure reliability under varied maritime conditions. The membrane is currently undergoing comprehensive testing and evaluation protocols aboard the OPV. Beyond its immediate military application, this technology demonstrates considerable potential for civilian use in coastal regions after appropriate modifications, potentially addressing freshwater scarcity challenges in littoral communities.
