Abstract: Based on the analysis of the characteristic of the solar and tidal energy and the technique of multi-effect
evaporation, an innovative solar multi-effect evaporation desalination is designed. Enhanced heat transfer techniques
such as falling film evaporation and condensation are used in the system. The uniqueness of the system is in the way
tidal energy is utilized to supply power for water supply and sewerage and creating vacuum instead of pumps powered
by electricity. In this way the operation cost of the unit can be reduced. The operation mechanism of the unit is
provided. Theoretical analysis of the operating mechanism of supplying power for water supply and sewerage and
creating vacuum by tidal energy is presented.
Keywords: solar energy , tidal energy, multi-effect evaporation, vacuum, desalination
