Solar Desalination Unit

Abstract

By means of solar energy potable water is produced from seawater or brackish well water in the process of desalination or distillation. The solar still consists of a shallow pool of brine covered by sloping panes of glass. The water is evaporated by absorbed solar radiation and the vapour condenses on the underside of the glass covers, which are cooled at the outside by convection. The water droplets trickle down the glass to be collected in narrow drains along the bottom.
