Diseño a escala de laboratorio de un desalinizador de agua multicapa por filtración lenta.

Abstract

Currently states such as Guajira, Choco, Bolivar among others, do not have access to fresh drinking water, however, the accessibility of sea water stands out as an abundant and constant source in this area, so a study of a multilayer water desalinator by slow filtration, as a sustainable and sustainable option through filter beds such as river sand, montmorillonite type clay, calcite type gravel and activated carbon classified as microporous materials was carried out. To determine the order of the layers, 24 tests were carried out selecting the two best ones according to the best flow time, color and pH control in the output solution, in determining the thickness of the layers, the retention capacity of each of the materials was evaluated separately and as a whole by monitoring conductivity, pH and temperature, the two best configurations are given by the following order from bottom to top, First=Coal-Clay-Sand-Gravel; Second= ClaySand-Gravel-Coal obtaining a desalination percentage of 11 .22 and 53.78% respectively determined by drying and by conductivity with 43.3 and 80% respectively. In addition, the X-ray fluorescence analysis showed an ion extraction capacity between 86.5 and 99.2%.
