Pretreatments for seawater desalination by pervaporation using the developed green silica/PVA membrane

In this study, different pretreatments were evaluated for the desalination of seawater by pervaporation using the green silica/PVA membrane. The quality of water samples treated by sand filtration, coagulation, coagulation + sand filtration and microfiltration was analyzed in terms of turbidity, total suspended solids (TSS), conductivity, pH and biochemical oxygen demand (BOD). The most viable pretreatment, based on the effluent quality and...
