Nanofiltration and reverse osmosis thin film composite membrane module for the removal of dye and salts from the simulated mixtures

A recent progress in thin film composite membrane: A review

“…Owing to ultrathin selective layer, reverse osmosis (RO) and nanofiltration (NF) membranes prepared using this coating technique have emerged as excellent candidates in a wide variety of separation applications, particularly in the water and wastewater treatment processes [2][3][4][5]. Despite TFC membranes have been well received in industry, there is still an interest among membrane scientists in making asymmetric membranes via single-step fabrication process [6][7][8][9][10].…”

Separation of ternary sodium chloride/Reactive Black-5 aqueous solutions using two different modules in a nanofiltration pilot plant

“…Membrane-based separation processes, which were the focus of attention of the separation technologists for the past three decades, have the potential to offer an improved separation and several cost advantages over these more traditional techniques. Various works have reported the use of nanofiltration (NF) membranes for dye separations either for wastewater treatment (Nataraj et al 2009;Mo et al 2008;Yu et al 2010;Uzal et al 2010) or process applications (Levenstein et al 1996). NF is becoming widely accepted in the dye-house wastewater treatment.…”

“…Cadmium toxicity cause renal disturbances, lung problems, bone lesions, cancer and hypertension in humans [19][20][21] Thus, the removal of these toxic metals from wastewater is a crucial issue. processes like adsorption, coagulation, co-precipitation, ion-exchange and oxidation-reduction process have been reported in literature for treatment of arsenic and removal of heavy metals from wastewater [22][23][24][25][26][27][28][29]. Among these processes, absorption is one of the promising methods.…”
