Proposta de dessalinizador solar híbrido

Abstract

The Northeast region of Brazil has very distinct edaphoclimatic characteristics when compared to other regions of the country, because it has dry climate and the soil is characterized by being shallow and sometimes with large amount of salts. Because of these characteristics, water from precipitation when infiltrates the soil carries the salts present in the superficial layers, increasing the concentration of salts in water that percolates to levels harmful to human and animal health. The wells in the region have saline water because of those characteristics, it is therefore necessary to adopt practices that can improve water quality, removing impurities, microorganisms, and salts present in the water. The solar desalination is a simple and easily replicated technology and studies have shown that it improves the quality of saline waters with impurities and / or microorganisms. This technology when used in conjunction with the solar concentrator, makes a gain in desalination system yield, because of the concentrator reflect solar radiation and concentrates the sun's rays on the desalination base, thus increasing the production of desalinated water. The Hybrid solar concentrator is also an easily replicable technology and can be built even with recyclable materials like mirrors and satellite dish, thus being an accessible and simple technology. In this work was developed and construction a 1.7 m² solar desalination area and a 1.7 m diameter solar concentrator and were installed in the rural area in the Poldrinhos settlement in the municipality of Serra Talhada / Pernambuco. Used mirrosand satellite dish and among other materials, resulting in an expense of R$ 1149.24. The use of hybrid solar desalination will increase the production of desalinated water compared to the flat solar desalination.
