Since water is the most important component of life on the planet, and for this reason, having drinking water has become a major global challenge for the 21st century. A possible alternative source of potable water supply is sewage sources [1,2]. Forward osmosis (FO) was investigated as a potential process for the removal of micro pollutants and shows a better performance in removing small solutes such as urea and micro pollutants compared to RO mode [3,4]. In These studies, thin films composite forward osmosis membrane (TFC-FO), were modified by Polyoxymetals nanoparticles The effects of Mo57 and Mo132 nanoparticles on the PES substrate morphologies, surface roughness, hydrophilicity, and water permeability were investigated by measuring the water contact angles, scanning electron microscope (SEM) imaging, FT-IR spectroscopy, and atomic force microscope (AFM) analysis. In order to evaluate the performance of membranes modified by Mo57 and Mo132 in direct osmosis processes in two states, PRO mode (the membrane active layer facing draw solution) and FO (the membrane active layer facing feed solution) mode, have been studied. The results indicated enhanced water permeability of the modified membranes upon the POMs addition, leading to significant enhancement in the water flux and Improving Performance of FO membrane.
