Nanofiltration (NF) with high water flux and precise separation performance Li+/Mg2+ selectivity is ideal for lithium brine recovery. However, conventional polyamide-based commercial NF membranes are ineffective in recovery processes due to their undesired selectivity. In addition, they constrained by the permeance trade-off, which means that a highly permeable membrane often has lower this stu...

hospital wastewater has special importance since having pathogens, radioactive materials, pharmaceutical wastes and heavy metals. removing them into environment without any treatment may cause serious problems for the public health. membrane biological reactor is the combination of the activated sludge and membrane filters. this research has investigated the performance of the nano-filtration i...

Abstract The good mechanical and chemical stability of textile acrylic fibers waste has promoted its candidacy for fabricating low cost membranes wastewater treatment. In this work, nanofiltration based on the were successfully prepared using phase inversion technique. First, membrane solutions with different concentrations (16, 18, 20, 22%) (AF) in dimethyl formamide (DMF) prepared. Evaluation...

Nanofiltration is a promising solution for the removal of emerging and persistent micropollutants, but it limited by operating expenses due to high membrane areas operational pressures, dictated membrane’s low molecular weight cut-offs (MWCO), formation large amounts concentrate be treated, e.g. advanced oxidation. In this paper, simple proposed enhance retention micropollutants adding cyclodex...

Desalination brine mining emerges as a solution to supply raw materials the European Union industry in circular economy approach since valuable minerals and metals (e.g., B(III), Mg(II), Ca(II), Sc(III), V(V), In(III), Ga(III), Li(I), Mo(VI), Rb(I)) are present seawater but low concentrations. Brine pre-treatment is important remove species that may impair performance of other technologies invo...
