Biofouling of reverse-osmosis membranes under different shear rates during tertiary wastewater desalination: Microbial community composition Academic Article uri icon


  • Abstract We investigated the influence of feed-water shear rate during reverse-osmosis (RO) desalination on biofouling with respect to microbial community composition developed on the membrane surface. The RO membrane biofilm's microbial community profile was elucidated during desalination of tertiary wastewater effluent in a flat-sheet lab-scale system operated under high (555.6 s− 1), medium (370.4 s− 1), or low (185.2 s− 1) shear rates, corresponding to average velocities of 27.8, 18.5, and 9.3 cm s− 1, respectively.
