Comparative study of distilled-water production from two solar stills : green house effect and capillary film

الملخص EN

The aim of our study is to look for an alternative solution of fresh-water supply in the case of Algeria.

The solar-still with greenhouse effect could agree with this purpose, as its design does not lead to technical problems.

However, its production of fresh water still insufficient.

Our study compares, in terms of water production, the performance of a simple solar-still with greenhouse effect with that issued from a solar-still with a capillarity film.

This can be done through the study of some parameters which intervene on the performance of the two systems, in order to increase distilled-water production.

Results issued from this work show that, for the same operation time, the solar-still with capillary film give better production, in terms of fresh water, compared to the simple solar still with greenhouse effect.
