A New Approach in Providing Water to Isolated Communities by Exploitation of Sustainable Energy Resources in Dry and Semi-dry Areas in Saudi Arabia

Abstract

The Arab countries, especially Saudi Arabia, occupy a prominent place in terms of their uniqueness of proximity to many sources of alternative energy. They are characterized for their long sun shining hours, e.g. Saudi Arabia is of a prime location to harness solar energy because of its year-round sunshine. The average energy from the sunlight falling on Saudi Arabia is 2200 thermal kWh/m 2. The winds perpetual motion, differences in weather conditions between different areas of the KSA create the opportunity for active air currents. It is characterized by an abundance of plenty underground soft water, salty water traps and plenty amounts of waste waters all over the country. Saudi Arabia was producing 18% of the worlds desalinated waters, It sounds as though the Kingdom recognizes the solar and winds potential it owns, that can be utilized for improving the level of life for the majority of its inhabitants especially those living in dry and or semi-dry isolated places which can be attained by providing the necessary quantities of water for individuals and for governmental interests in these areas.

On the Perspective of Applying of a New Method for Wastewater Treatment Technology: Modification of the Third Traditional Stage with Two Units, One by Cultivating Microalgae and Another by Solar Vaporization

“…This research-project will offer a sustainable solution to well-known environmental problems such as the domestic drinking water-supply and sewer systems associated with the rapid population growth Amous [5]. Besides the obvious benefit of cleaning, recycling of waters and biomass production, this research-project will pursue a number of other sub-objectives that are also important for the biotechnology sector.…”

“…There are several technologies for the treatment of water/ wastewater, but the available methods depend on their availability and economic factors Al Arni S [1], Ghernaout [2][3][4], Amous [5]. In this regard, the biological removal of contaminants by microalgae is one of the most promising because it utilizes contaminants, as nutrients to culture biomass, and sunlight as the energy source for photosynthesis, both being free Souza [6].…”
