Effect of operating conditions on biofouling in reverse osmosis membrane processes: Bacterial adhesion, bioﬁlm formation, and permeate ﬂux decrease We systematically evaluated the effects of operating conditions on biofouling behaviors in reverse osmosis (RO) membrane processes. The biofouling experiment was performed by ﬁltrating nutrient-containing feed water with a cross-ﬂow cylindrical membrane cell through a circular polyamide RO membrane Desalination 378 (2016)
Biofouling resistance of polysulfobetaine coated reverse osmosis membranes • The polymer brushes were successfully grafted from the surface of RO membranes. • The modiﬁcation with pSBMA provides densely packed, regular length polymer chains. • Very stable hydration shell on the monomer segments within the polymer chain was formed. • Modiﬁed membranes showed a minimum of at Desalination 369 (2015)
Effect of membrane surface characteristics on hydraulic flux balance and feed stream translation in concentrate multi-stage system Concentrate staging which is one of the configurations of reverse osmosis membrane system has made hybridization of different types of membranes such as sea and brackish water reserve osmosis membranes possible. And the essence of hybridization of membranes is to equilibrate permeate and lower energ Desalination 249 (2009)
Prediction of boron transport through seawater reverse osmosis membranes using solution–diffusion model One of the key transport parameter—permeability, is being used as an intrinsic characteristic of membrane for reverse osmosis process prediction. In this study, the prediction of reverse osmosis process in terms of boron rejection was carried out in two steps. First, the permeability of boron existi Desalination 249 (2009)
Small reverse osmosis units using PV systems for water purification in rural places Large-scale reverse osmosis (RO) plants with productions of the order of several cubic meters per day are extensively used throughout the world for water desalination. These systems, using electricity for running the high-pressure pumps, are among the ones with the lowest cost per cubic meter of wat Desalination 137 (2001)
The effect of surface characteristics on RO membrane performance The characteristics of membrane surface have a significant effect on membrane performance. In this study two commercial reverse osmosis membranes both made from polyvinyl alcohol named TFC-ULP and TFC-SR2 were challenged with tap water. The performances of the membranes were completely different. Fo Desalination 139 (2001)
