Resumo


The semi-climatic conditions of the Brazilian Semi-arid have conditioned the water shortage, which has forced numerous rural families to consume brackish waters unfit for human consumption. Added to this is the fact that the poor management of local water resources is an aggravating factor to unavailability of water, especially drinking water. The technologies have proved to be medium for the efficient management of water resources. The present study aimed to analyze the use of solar desalinizers can offer drinking water with the use of solar energy. An experimental and qualiquantitative research was carried out, based: data collection; Field studies, with accounting for the production of drinking water; Conducting physical-chemical analyzes of water; And participatory research with families that consume the waters from desalinators. As result, there were: there is, locally, a great solar energy potential; There was an average production of 40 liters / day, which met the needs (2 liters / person / day) of 20 individuals distributed in 5 families; physico-chemical analyzes proved the potability of the water coming from the desalinators; And the use of desalinators has made possible socioeconomic and environmental benefits. It was concluded that desalinators are socially disseminable, economically viable, and environmentally sound technology.
