Synthesis and characterization of polyether sulfone/ polyethylene glycol/ montmorillonite nano mixedmatrix membrane for removal of phosphate from water

Eutrophication is one of the most problematic water pollution, caused by the high level of nutrients in water, mainly phosphate, which is due to the fertilizers runoff from the agricultural areas, as well as the untreated disposal of domestic and industrial wastewater into the environments. Besides,...

Performance of prepared membranes was determined in terms of the water flux and removal by changing conditions of pressure range 1 to 3 bar and pH form 2 to 10 as well as OMMT nanoparticles concentration 1 to 7 wt.%.

Eleven different membranes, containing different ratios of PES, OMMT nanoparticles and PEG were sampled in order to prepare optimum membrane. At 1 bar pressure and 50 ppm phosphate concentration the neat PES membrane successfully achieved rejection of phosphate up to 97.6 % and water flux up to 2.26 L/m2. h whereas the optimum membrane achieved rejection of phosphate up to 94.70%, water flux up to 49.2 L/m2. h, and the optimum pH was pH4.
