New Delhi, May 16 -- 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), DRDO's 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 oper...
