Diagnóstico dos dessalinizadores no nordeste do Brasil

Abstract

The Brazilian semi-arid region is characterized by irregularity and low rainfall rates, as well as high rates of evapotranspiration and the predominance of crystalline rocks, which impact the groundwater quality. These high saline levels favour scarcity, being access to good quality water for human, animal and productive development a major challenge. The objective of this study was to quantitatively and qualitatively evaluate the current situation of the desalination plants in the municipality of Pesqueira in Pernambuco, Brazil, through technical visits and questionnaire application to community members. Thirteen (13) desalinators were identified in the studied municipality, providing potable water for the population of these regions, of which seventy-seven percent (77%) are fully functioning, and thirty percent (30%) of those do not have a system for the use of concentrated water, this being one of the main environmental problems associated to desalination.
