Siphon-Powered Desalination System

Recently, scientists at the Indian Institute of Science (IISc), supported by the Department of Science and Technology (DST), developed a siphon-based thermal desalination system that can convert seawater into clean drinking water efficiently and affordably.

What is the siphon-based desalination system?

  • The system operates on the simple principle of siphonage, using gravity to maintain continuous water flow.
  • It consists of a composite siphon made of a fabric wick and a grooved metallic surface that draws saline water and prevents salt crystallization.
  • As water flows as a thin film over a heated metal surface, it evaporates and then condenses on a cooler surface ....
