| Abstract: | Application of the multiple-effect concept to the direct utilization of solar energy in atmospheric distillation of saline water has been investigated experimentally. Considerable improvements in productivity are obtained because of re-use of latent heat, especially for high levels of insolation. It is found that a double-effect solar still (with two glass covers on the top. liquid feed as coolant and preheated on the outside surface of the bottom plate) may yield high productivity. |
