Abstract

The use of solar-water desalination is one of the most promising and environment friendly means to meet the ever-increasing demand of fresh water in freshwaterscarce communities. Unfortunately, desalination of water is a highly energyintensive process. Nonetheless, direct solar-water desalination is simple in design, low in cost, and can easily support the daily use of communities. This chapter describes various types of solar-water desalination with a focus on technologies that are suitable for small communities and remote areas. Mathematical modeling of direct solar-water desalination based on convective, radiative, and evaporative heat transfer has been provided. A case study from Pasni, District Gwadar, Balochistan of Pakistan involving design, fabrication, and cost is included to give an overview of the practical operation of technology.
