Research progress of novel membranes for membrane distillation against wetting,fouling and scaling
Membrane distillation(MD)has attracted widespread attention as a promising technology for high-salt wastewater treatment.However,due to the complexity of the actual wastewater composition,the practical application of MD still faces three key challenges:membrane wetting,membrane fouling and membrane scaling,which ultimately lead to reduction of membrane flux and selectivity,even membrane failure.In this study,the characteristics and causes of membrane wetting,fouling and scaling induced by different kinds of substances were briefly described.Subsequently,it focused on the current research progress of novel membranes against wetting,fouling,and scaling,including the design principles,resistance mechanisms and the application scopes.In addition,methods of pretreatment,operating condition regulation and membrane regeneration were also discussed to further ensure the long-term stability of MD.
