Water desalination using thermal applications of solar energy [electronic resource].

Includes references.

Desalination of brackish water by solar powered systems is a practical and promising technology for producing potable water in the regions which suffers from water scarcity especially in arid areas. Therefore, a small-scale solar powered desalination system has been constructed and operated for using the desalination solar technology to produce the fresh water, for domestic use. In the present investigation, a parametric study of passive solar still is presented, to improve the solar still performance. To increase the productivity of this solar still, a flat plate solar collector was integrated with the solar still (active solar still). Hence, the present study aims to evaluate and compare between passive and active solar stills based on the productivity values. The obtained data showed that by applying solar still cover cooling, the highest productivity is 7.80 I/m2.d. when the glass cover inclination is 0.436 rad (25 deg.) and the [) water basin depth is 1cm for passive solar still. The highest productivity for active solar still is 10.06 IIm2.d. when the flat plate solar collector inclination is 0.436 rad (25 deg.).
