About Low Temperature Thermal Desalination Technology:
- It is a process under which the warm surface sea water is flash evaporated at low pressure and the vapour is condensed with cold deep sea water.
- The LTTD technology does not require any chemical pre and post-treatment of seawater and thus the pollution problems are minimal and suitable for island territories.
- Significance: Since no effluent treatment is required, it gives less operational maintenance problems compared to other desalination processes.
- The first LTTD plant in Lakshadweep was commissioned in Kavaratti in 2005.
