This project presents the crystallization of rejected brine from seawater reverse osmosis (SWRO) plants through an innovative Membrane Distillation Crystallization (MDCr) system. In addition, it provides a sustainable brine management process, enabling resource recovery, which has greater economic importance. Therefore, this approach also helps in mitigating environmental challenges associated with the brine disposal. Preliminary findings from the pilot-scale implementation will demonstrate its technical feasibility and highlights economic advantages as membrane crystallizer.
