- •
A procedure to estimate the unit exergy cost of water treatment techniques is provided.
- •
Unit exergy costs of water purification and desalination are given as a function of design and operating parameters.
- •
Unit exergy costs range from 3.3 to 6.8 in purification and from 2 to 26 in desalination.
- •
They could be used in their preliminary design as good indicators of their energy efficiency.
