  • Evaluating impact of fouling on reverse osmosis membranes performance

    Abstract Membrane fouling is commonly defined as an undesirable formation of deposits on mem- brane surfaces and it is considered a major problem in most brackish, seawater, and waste water reclamation applications. Depending on nature of the scale and foulant, fouling pro- cesses will lead to decreased membrane fluxes, increased pressures needs, and/or increased permeate conductivity. ...
