The production of polysulfone (PS) membrane with silver nanoparticles (AgNP): Physical properties, filtration performances, and biofouling resistances of membranes

► The work focused on bare and AgNP composite polysulfone membranes. ► Biofouling mechanism was determined with disk diffusion test and PCR-DGGE technique. ► Membrane characteristics was examined using SEM, contact angle and AFM techniques.
