The increase in water consumption and the reduction of its resources generated a need to create advanced treatment technologies. The development of a membrane process for water desalination and purification has gained importance to ensure human consumption and industrial requirements. CVD graphene membranes are being considered one of the most promising alternative for desalination and water treatment. The development of graphene technology will allow the rise of a new class of membranes. The first studies indicated a high potential increase in flux and selectivity, as well as mechanical resistance and antifouling properties, as compared to commercial polyamide thin-film composite membranes. A literature review has been performed to elucidate the main concepts and techniques reported in experimental works aiming at the development of composite membranes with a selective graphene layer over a porous substrate for water desalination. The bottleneck of production steps were highlighted: chemical vapor deposition of graphene, transfer of graphene films, defect minimization and the production of pores with controlled sizes.
