This study focuses on the water quality assessment (feed, product and brine) of the pilot adsorption desalination (AD) plant. Seawater from the Red Sea is used as feed to the AD plant. Water quality tests are evaluated by complying the Environmental Protection Agency (EPA) standards with major prima

In many places world wide drinkable water is already a scarce good and its lack will rise dramatically in the future. Missing energy sources and no grid connections complicates the use of standard desalination techniques in these places. Fraunhofer ISE develops solar thermally driven compact desalin

Water scarcity is a major problem in many developing countries. Depending on precipitation intensity rainwater constitutes a potential source of drinking water. In addition, its proper management could reduce water and food crisis in some of these regions. Rainwater harvesting (RWH) is a technology

The characteristic equation has been used for experimental results of a passive solar still to generate linear and non-linear characteristic equations for winter and summer conditions. The different angles of inclination of condensing cover (15°, 30°, 45°) have been chosen for winter and summer cond

This paper shows the principles and the present state of the art of concentrating solar power technology and explains the option for seawater desalination, either using electricity or steam generated in such plants. The economic potential of this technology in the MENA region can cope with the prese

Nowadays, more than 110 cities of China confront the serious problem of fresh water shortage, and more than 70% of the rivers and lakes are contaminated to some extent. About 38 million people are depending on brackish water for life. Desalination of seawater and brackish water is one of the ways to

The use of solar energy in thermal desalination processes is one of the most promising applications of the renewable energies. Solar desalination can either be direct; use solar energy to produce distillate directly in the solar collector, or indirect; combining conventional desalination techniques,

The integration of renewable resources such as solar and wind energy is becoming increasingly attractive. This is being used widely for substitution of oil-produced energy and will help to minimize atmospheric degradation. The major advantage of a hybrid system is that when solar and wind power prod

A sun tracking system was deployed for enhancing the solar still productivity. A computerized sun tracking device was used for rotating the solar still with the movement of the sun. A comparison between fixed and sun tracked solar stills showed that the use of sun tracking increased the productivity

The paper presents a long-term scenario for the demand of freshwater in the Middle East and North Africa (MENA) and shows how it may be covered by a better use of the existing renewable water sources and by sea water desalination powered with solar energy. Growth of population and economy, increasin
