Abstract
With drinking water becoming scarce, it becomes imperative to find ways to better manage and produce potable water at low cost. In this paper, desalination methods have been discussed, the approaches to reduce their production cost and increasing performance have been investigated, the method of transferring water through Saudi Arabia, the possibility to use renewable energy and supporting KSA 2030 vision for desalination projects have been explored. One of the more precious projects related to KSA view 2030 is water desalination based on solar energy and decentralized the productivities; therefore, in the present study, we develop a small system to produce water for some families. The technology and materials used will have to be simple and easily available so that the system can be built anywhere based on solar energy at small cost. This model is therefore not only economically viable, but also small factories with solar collector enhance flow rates of potable water; these units could easily become profitable in non-oil producing countries and therefore will match with the new KSA vision. The present study proves that in case of low flow leads to more moisture at the outlet of the evaporator.
