Advanced Membrane for Seawater Desalination

On 15th May 2025, the DRDO developed a high-pressure nanoporous polymeric membrane tailored for desalination under harsh marine conditions. Developed by DMSRDE, Kanpur, the tech is designed for Indian Coast Guard use.

Key Points

Developed by DMSRDE: The Defence Materials Stores and Research & Development Establishment completed development in just eight months.
Chloride Resistance: Engineered to resist degradation from chloride ions present in saline water.
ICG Application: Specifically created to meet desalination requirements on Indian Coast Guard Offshore Patrolling Vessels (OPVs).
Successful Trials: Initial technical trials on an OPV were successful; final clearance awaits 500 hours of testing.
Civilian Use Potential: With minor tweaks, the technology could be adapted for coastal civilian desalination systems.
