The presence of recalcitrant contaminants in wastewater is a major challenge. Membrane technologies have received industrial attention, but membrane fouling is a setback. This review focuses on polymeric membranes with antifouling properties, discussing surface properties, fabrication, characterization, biocatalysis, and application.
The presence of recalcitrant contaminants in wastewater is major challenge to decrease pollution and associated health issues. As a consequence, membrane technologies have recently attracted industrial attention, yet a major setback of membrane employment is membrane fouling which leads to frequent discarding of membrane modules. More than 45% of all membrane fouling cases are caused by biofilms that are resistant to antimicrobial agents. Here we review polymeric membranes with antifouling properties, with focus on surface properties, fabrication, characterization, biocatalysis using enzymes and application towards the removal of dyes, phenol, pesticides and fertilizers. Nano-engineered fabrication of polymeric membranes allow to decrease fouling by 80-90%. Immobilized oxidoreductases in polymeric membranes allow 65-98% removal contaminants in wastewater.
