Avaliação da viabilidade de uso da água dessalinizada

Abstract

The importance and value of water have been increasingly emphasized in recent years due to global population growth, rapid industrialization, and urbanization. Water is essential for life and plays a critical role in natural and human processes, despite the hydrological potential found in the rocks that form the soil. Since the 1950s, desalination technologies have advanced rapidly, driven by the growing global demand for water. These technologies are based on the principles of the natural hydrological cycle. This study aimed to design and build a solar desalination device, evaluate the quality of desalinated water, and analyze the impact of this innovation. The construction of the solar desalination unit was carried out in stages, using materials such as wooden boards, nails, glass, wood glue, Styrofoam, black plastic, a saw, tubes for draining saltwater and potable water, and a thermometer to monitor internal and external thermal conditions. The solar desalination device operates by harnessing solar radiation to create the necessary internal temperature for desalination. To assess the efficiency of the device, climatological data such as average temperature variations, precipitation, relative humidity, atmospheric pressure, and solar radiation were collected. The desalinated water samples were analyzed at the Water Supply Investment and Asset Fund, focusing on organoleptic, physical, and chemical parameters. The results confirmed that the desalinated water meets the standards for human consumption, ensuring compliance with public health requirements.
