ResumoPharmaceutically active compounds are a real threat all around the world. Conventional water and wastewater treatment are not efficient in removing this kind of organic micropollutants of emerging concern. Advanced treatment processes seem to be a good alternative for PhACs removal either in drinking water or wastewater. Membrane separation processes were proved to be a good treatment option since they are able to produce a high quality permeate without increasing its toxicity. Microfiltration, ultrafiltration and membrane bioreactor can be applied to the treatment of wastewater due to the high concentration of organic matter. Nanofiltration and reverse osmosis are mainly applied for water treatment. Their rejection mechanisms and the interactions between PhACs and NOM or inorganic salts are well understood. It is consensual that tighter NF membranes are more efficient than looser membranes, reaching >99% of removal. Membrane distillation is a relatively new technology especially because of its robustness in dealing with a broad spectrum of pollutants, however only a few studied are focused on the application of MD in removing PhACs from water and wastewater and few are known about the rejection mechanisms and the interaction between PhACs, NOM, inorganic salts and membrane. MSP, specially MD, is a very promising technology to be applied in order to prevent public health and environmental problems caused by the release of PhACs in the environment.
