ABSTRACT The emergence of new contaminants, owing to the persistently high levels of water pollution, has rendered most conventional water purification techniques inadequate and/or relatively costly. In this study, a simple, effective and affordable prototype membrane filter was fabricated, with the use of Comsol Multiphysics simulations. These simulations were used in the real-time prediction of the water-retention and lifetime of the fabricated membrane. The river and hand-dug well water sa...
