Abstract: 

Producing potable water is a critical issue due to the lack of access to clean H2O and the increasing demands of environment. One of the main technologies for water purification is solar still using the sustainable and green source of energy. To augment the efficiency of solar unit, nanoparticles are combined with the saline water. Nanofluids are suspended materials that besides the different geometries (single slope, double slope, tubular…) of the solar stills have a significant impact on improvement of the thermal conductivity of the brackish H2O. Further, combining nanomaterial with solar energy system appears to be more cost-effective approach for potable water production since they boost the evaporation and condensation rate. This paper is a comprehensive literature on different types of nanofluid and various numerical, experimental and analytical methods that researchers have applied to augment the efficiency of system.
