Abstract
Fresh water scarcity is expected to be one of the major risks for society in the future, since the global water demand is constantly increasing at around 1% pace per year achieving a nearly 30% increase by 2050 due to population growth and industrial development. Seawater's desalination is a sensible choice because seawater represents more than 96 % of the total global water. The world’s sustainability will be severely ensured by production of clean water and new energy sources that are intimately connected in the next decades. The membrane technology has become increasingly important in separation processes amplifying its fields of applications. The solar-driven evaporation process in medium porous can be promising choice to make salt-water into fresh from the use of Direct Contact Membrane (DCM). This work has as main aim the mathematical modelling to describe solar-driven seawater desalination process on the solid open-cell foams (-SiC) using the DCM technology. The desalination system's variables describe the specific aims from each equation of the physical-mathematical model for characterizing the performance of the heat and mass transfer from seawater evaporation process. In addition, this study investigates the evaporation characteristics of droplets when placed on the heated DCM system to check the efficiency of solar energy utilization in solar driven fresh water generation.
