Description
Summary:The worldwide scarcity of freshwater for human consumption has increased the difficulties faced by many populations on a daily basis. In coastal regions, there is access to abundant amounts of brackish water, despite this; its characteristics do not allow it to be used to meet the needs of the populations. As alternative solutions to the need to provide fresh water to these populations, research and processes have been developed to achieve seawater desalination. There are various technologies, such as multi-effect distillation (MED), multi-phase distillation (MSF), reverse osmosis (RO) and solar distillation, among others, in which solar distillation represents the simplest alternative given the need and socioeconomic characteristics of these technologies populations. This research shows the results obtained from the tests carried out with a pyramidal solar still in the city of Sincelejo, Colombia, in order to determine the feasibility of this technology in populations with access to brackish water. In the tests carried out, the behavior of the temperature of the water, the solar still and a control container were recorded throughout the day, at intervals of 30 minutes, and a meteorological station that allowed recording the behavior of solar radiation, humidity wind speed, ambient temperature, among others, parallel to the performance of the tests. The different analyzes carried out on the data obtained made it possible to find adequate conditions for the performance of this type of technology, despite the rainy season in 2022. Solar distillation represents an alternative that in the future will allow access to fresh water for many people who today do not have it. Under the climatic conditions of the area, an estimate of production of up to 1.62 liters of desalinated water per square meter of pyramidal solar still was achieved, which can be used in many ways by vulnerable populations for consumption.
