The product :
The objective is to develop a simple, economic, reliable and robust multistage solar still to produce pure water for domestic and socio-economic uses from sea water and of brackish water abundant in several isolated regions of the Algerian Sahara. The multistage still of laboratory is a research tools to identify the variables and to quantify their effects on the productivity. a new technology was worked out , it was the object of an invention patent deposit on the date : January 4th, 2012, INAPI, Reference: 120011.

Socio-economic impact:
- To offer an intelligent equipment of brackish and sea water desalination to meet the domestic needs of fresh water at small scales in the isolated regions of Algeria.
- To satisfy the distilled water needs for the isolated regions.
- To set-up an Algerian technology of desalination and production of distilled water by solar energy, autonomous and self-regulated for the isolated regions
Applications:
La faible consommation énergétique et sa neutralité vis-à-vis de notre milieu naturel ont fait de ce système un équipement de choix dans:
- Habitat
- Bâtiments industriels
- Batteries d'élevage
