Fabrication of Polyethersulfone (PES) membrane by adding Tin Dioxide (SnO2) using the flatsheet method. In this study, the effect of the addition of SnO2 will be analyzed to determine the mechanical properties of the membrane, as well as the performance of water treatment. The PES@ SnO2 membrane was characterized by SEM and the pore size was uniform until the addition of SnO2 reduced the surfac…
