DRDO develops high-pressure polymeric membrane for sea water desalination
What is Desalination:
Desalination is the process of extracting salts and other minerals from water, usually from seawater, to make it fit for drinking, irrigation, or industrial applications.
What DRDO developed:
India's Defense Research & Development Organization (DRDO) has successfully created its own indigenous nanoporous multilayered polymeric membrane This technology was developed by DRDO's Kanpur lab, the Defense Materials Stores and Research & Development Establishment (DMSRDE), to meet the needs of Indian Coast Guard (ICG) ships. DMSRDE developed this solution quickly, in just eight months.
DMSRDE and the ICG have already tested this new membrane in a desalination system on an ICG ship. The early tests for safety and how well it works have been very positive. The ICG will give its final approval after 500 hours of real-world use.
Currently being tested on a Coast Guard ship, this membrane could be very useful for making seawater drinkable in coastal areas after some adjustments. This development by DMSRDE is another step towards India becoming self-reliant in technology.
The Navy/Coast Guard ships need to be in the Sea for a long time, In these period they need a pure drinkable water, while these technology is implemented the sea water can be used by the Crew members in the ship for the Drinking water and other purposes.
