- National Institute of Ocean Technology (NIOT) is working at making the Low-Temperature Thermal Desalination technology process free of emissions.
- Desalination is a process that takes away mineral components from saline water. It is used in places where freshwater supplies are scarce and seawater is readily available.
- Desalination is easily scalable and can be used irrespective of weather conditions.
- LTTD which stands for Low-Temperature Thermal Desalination exploits the difference in temperature (nearly 15°C) in the ocean water at the surface and at depths of about 600 feet.
- This cold water is used to condense water at the surface.
- The water at the surface is warmer and is maintained at low pressure using vacuum pumps.
- water evaporates at ambient temperatures at such low pressures and this resulting vapour when condensed with the help of cold water from the depth is free of salts and contaminants and is fit to consume.
