Improvements in or relating to apparatus for the desalination of seawater. The invention relates to desalination apparatus which utilises solar energy and is thereby capable of continuously providing sufficient pure water for drinking, irrigation, etc. economically. A lagoon for seawater is heated by solar energy and the seawater is transferred to a vacuum boiler (30), steam being delivered through a turbine (54) to a condenser (22). The turbine (54) generates the power necessary for the running of the apparatus. Pure water is collected from the condenser (22) and the seawater remaining in the boiler (30) is returned to the lagoon through flexible tubes (14) arranged on a terraced support sloping down to the lagoon, the tubes (14) defining a collector for solar energy. The salinity balance in the seawater returned from the boiler (30) is maintained continuously by a flow circuit (44, 48) so arranged as to require no additional power consumption. |
