Officials said Thursday that the Defense Research and Development Organization has successfully developed an Indigenous “nanoporous multilayer polymer membrane” for high-pressure seawater desalination.
The Ministry of Defense said the technology was developed for the “Indian Coast Guard’s desalination plant in the Coast Guard” based on its operational requirements to address the stability challenges when exposed to chloride ions in salt water. The development has been completed in “8 months of record time”.
DRDO “successfully developed indigenous nanoporous multilayer polymer membranes for high-pressure seawater desalination”, the ministry said in a statement. DMSRDE, together with ICG, successfully conducted initial technical trials in the ocean round-trip factory of the existing Maritime Patrol Vessel (OPV) of the Indian Coast Guard.
“The initial safety and performance tests of the polymer film were found to be completely satisfactory. After 500 hours of operational testing, the ICG will give the final operational clearance.” Currently, the unit is undergoing tests and trials on the OPV.
It said: “After some modifications, this membrane will be a boon for seawater desalination in coastal areas. This is another step in DMSRDE’s journey in Aatmanirbhar Bharat.”
