Membrane distillation is envisaged to be a promising best practice to recovery freshwater from seawater, due to the existent prospect to build up low energy-consuming devices powered by natural and renewable energy sources in remote and low accessible areas. Moreover, there is an additional benefit given by the possibility to integrate this technology with other well-established operations dedicated to desalination. Today, the development of membrane distillation depends on the productivity-efficiency ratio on large-scale. Despite that hydrophobic commercial membranes are widely used, no membranes with suitable morphological and chemical features are readily available on the market. Thus, there is a real need to identify best practices for developing new efficient membranes for more productive and eco-sustainable membrane distillation devices. Here, we propose engineered few-layer graphene …
