AB  - Today, it is extremely urgent to face the increasing shortage of clean and safe 
      water resources, determined by the exponential growth of both world population 
      and its consumerism, climate change and pollution. Water remediation from 
      traditional chemicals and contaminants of emerging concerns (CECs) is supposed to 
      be among the major methods to solve water scarcity issues. Reverse osmosis (RO) 
      and nanofiltration (NF) membrane separation technologies have proven to be 
      feasible, sustainable and highly effective methods for the removal of 
      contaminants, comprising the extremely persistent and recalcitrant perfluoroalkyl 
      substances (PFASs), which failed to be treated through the traditional water 
      treatment approaches. So far, however, they have been unable to assure PFASs 
      levels under the established guidance limits for drinking water and still suffer 
      from fouling problems, which limit their large-scale application. Novel 
      configurations, improvement in process design and the development of 
      high-performant materials for membrane production are important steps to tackle 
      these issues, especially in view of new more stringent regulations limiting PFASs 
      content in drinking water. As a possible future strategy, nanocomposite mixed 
      matrix membranes (MMMs) offer a platform of advanced materials which promise to 
      revolutionize RO/NF technologies for water treatment. In particular, the 
      introduction of MOFs as adsorbent fillers in the polymeric membrane matrix 
      appears as a viable approach for the effective and selective capture and removal 
      of PFASs from water. The objective of this review is to provide a dedicated 
      outlook on the most recent advances in RO and NF membrane technologies for PFASs 
      removal. The effects of membrane properties, the solution chemistry, and 
      contaminant properties on the RO/NF performances will be discussed in detail. 
      Future challenges are also discussed, offering new perspectives toward the 
      development of new advanced membranes with improved performance for PFAS removal, 
      which are likely to significantly progress RO and NF technology for water 
      remediation.
