Membrane systems are of significant importance in the processes of mineral recovery and water reclamation from wastewater, particularly in response to the growing need for fresh and reusable water resources. Membrane  crystallization (MCr) is a new technique that has arisen in response to the demand for the production and retrieval of  superior crystals from saltwater and wastewater. This process allows for the manipulation of polymorphic morphology by  adjusting the operational parameters. Furthermore, the utilization of membrane crystallization in conjunction with  membrane distillation or pressure-driven membrane techniques like nanofiltration and reverse osmosis has demonstrated the potential for attaining substantial desalination efficiencies. Nevertheless, there are still lingering issues within the realm of film crystallization technology. The main factors encompassed in this category are temperature polarization, contamination, and wetting. This study elucidates a novel technological advancement and showcases its diverse range of applications.
