“…46 The casting speed also affects the membrane morphology, porosity and pore size which is attributed to the alternation of the molecular orientation caused by the induced shear rate. 35,[56][57][58] It was also shown that the overall thicknesses of the membrane as well as the top layer increased by increasing the casting knife gap. [59][60][61] The main objective of the present research was to perform a systematic investigation on the effect of key parameters involved in the development of asymmetric NF membranes from the viewpoint of formation, structural characteristics, productivity and separation performance.…”

“…Phosphate anions, H 2 PO À 4 and HPO 2À 4 , were also demonstrated to be retained by NF200 at 85% and at 96%, respectively (Ballet et al 2007). Other authors have reported that polyethersulphone membranes rejected up to nearly 70% of NH 3 eN in solution (Ali et al, 2010). NF membranes have a potential role in the recovery of valuable resources from aqueous solution.…”
