Abstract:
The seawater desalination process currently uses membrane technology because of relatively lower investment and energy requirements. The process of seawater desalination using membrane process technology can be done in 3 methods, namely reverse osmosis (RO), distillation membrane (membrane distillation / MD) and pervaporation process (PV). This study will examine the performance of a hybrid membrane developed from natural zeolite-TiO2 with polyvinyl alcohol (PVA) in addition to polyethylene glycol (PEG) for desalination of seawater. The addition of PEG to the PVA polymer solution (dope) will increase the membrane resistance (Rm) and seawater rejection. The higher rejection is achieved of 93.77% at the addition of 6% PEG. Fouling resistance (Rf) isn’t affected by PEG concentration. The fouling resistance has good linearity and stability at the addition of 6% PEG
