Cascade type solar desalinizer applied in artesian wells in Paraíba interior

Abstract

For human consumption and other domestic activities, residents of the Brazilian semiarid use water from different sources. Therefore, the analysis of water quality is of vital importance, mainly because they use well water with high salinity content. In contrast, it is a territory with a high incidence of solar radiation, which is essential for desalination via solar energy. Thus, in this research, physical-chemical analyzes of alkalinity, chloride, electrical conductivity, hardness, pH, sodium and turbidity were carried out, in order to determine the water quality before and after the solar desalination process, in addition, the performance of the desalinator was evaluated. The desalinated water showed very efficient results in the removal of the physicochemical parameters studied, with the same according to the potability standards required by the Ministry of Health Ordinance in force in the country.
