Abstract:
... Osmotic distillation (OD) membranes offer selectivity based on vapor pressure and therefore highly reject all non-volatile contaminants. Despite the advantage of high selectivity, OD membranes have not been widely implemented due to poor water fluxes and detrimental heat transfer effects. In this study, we use element- and module-scale computational modeling to examine how OD membrane optimization ...
