In this work, a humidification–dehumidification process is considered as an advanced technique to design and construct a solar water desalination system. In this system, the salt water is heated in a solar collector before flashing inside an insulated chamber to b ...

... content water good enough for all domestic purposes other than drinking. Then each household produces its own drinking water by installing small solar desalination stills on the roof or in the garden. For any desalination unit to be domestically acceptable its efficiency should be reasonably hig ...

... particular location under consideration. It was found that dust deposition decreases the specific water production (m3 of water per kJ of incident solar radiation) and increases the specific power consumption (kWh per m3 water). Desalination 239 (2009) 66–81 Seasonal effect of dust deposition on ...

... “large” solardriven MD desalination units. The exergy efficiency of the compact and large units with reference to the exergy collected by the solar collector was about 0.3% and 0.5% but was 0.01% and 0.05%, respectively, when referenced to the exergy of solar irradiance. The exergy efficienc ...

Single basin solar still is a very simple solar device used for converting available brackish or waste water into potable water. This device can be fabricated easily with locally available... falling on the side walls of the still onto the basin reflecting mirrors are fixed one the side walls. This increases the insulation effect also. Desalination 220 (2008) 677–686 Progresses in improving the effectiveness of the single basin passive solar still K. Kalidasa Murugavela, Kn.K.S.K.

... desalination is increasingly recognized as a viable option. In arid coastal areas, the lack of fresh water coincides often with an abundance of solar energy. Coupling desalination systems with renewable energy technologies is of great importance. Project SMADES funded by the EC has sponsored th ...

A detailed analysis of low power (100 kW) solar-driven Rankine cycles in the medium temperature range has been carried out. Toluene, octamethylcyclotetrasiloxane (D4) and hexamethyldisiloxane (MM... out for condensation temperatures in the ORC between 35ºC and 115ºC so that thermal power rejected can be used in different ways related to desalination processes (preheating of reverse osmosis feed, heating of feed of conventional or membrane distillation processes). The results obtaine ...

... a numerical analysis to investigate the effect of the vertical flat plate external reflector on the distillate productivity of the tilted wick solar still. We propose a geometrical method to calculate the solar radiation reflected by the external reflector and absorbed on the evaporating wick,... in all but the summer seasons, and the increase in the daily amount of distillate averaged over the four days is predicted to be about 9%.
