Revolutionizing Seawater Desalination: DRDO’s Advanced Polymeric Membrane Technology

Introduction: The Importance of Seawater Desalination

In an era where fresh water is scarce, desalination stands as a vital solution. As the world’s population grows and urbanization intensifies, providing clean, fresh water becomes a pressing challenge. The Indian Coast Guard (ICG) ships are pivotal in this effort, using high-pressure polymeric membranes to extract water from seawater. This technology not only saves precious resources but also ensures sustainable water availability.

** DRDO’s Journey to Innovation**

Driven by the growing demand for clean water, DRDO emerged as a leader in advancing desalination techniques. In eight months, they developed a high-pressure polymeric membrane. This innovation is designed to improve water availability in regions with salt-rich waters, addressing both environmental and community needs.
