Estudo de um dessalinizador solar de água visando aplicações na área de tecnologia social

Abstract

Access to tap water seems to be one of society's most recurring problems. To this day, many regions around the globe struggle to have available clean water or even end up consuming untreated water. This article presents a theoretical and experimental study of desalination as a social technology, in which a masonry solar still is manufactured using easy to find, low-cost materials, by the population itself. The structure consists of joining two pieces of glass together in an angle as to create a double-slope roof system, which has been shown to be more effective than a single-slope one. In addition to that, the system works with materials that naturally absorb solar energy since this is an essential element to the still. The results show a 37% efficiency rate, which, when compared to previous studies, is proved to be satisfactory.
