Abstract

A portable solar stil with integrated radiation reflectors was used to obtain treated water with human consumption standards. This article aimed to analyze the thermal performance of the solar still to produce desalinated water and the physical-chemical quality of the water before and after the desalination process. The brackish water sapled in the well at Poço de Pedra Farm, in the municipality of Juazeirinho - PB. Maximum drinking water production of 2730.8 mL m-2 day-1 observed for an average solar radiation index of 660.42 W m-2. The results obtained from the physical-chemical analysis of brackish and desalinated waters showed reductions in the chloride content of 99.72%, sodium of 99.88% and total dissolved solids of 99.73%, reaching values in accordance with the standards of potability required by the Ministry of Health.
