Micellar enhanced ultrafiltration (MEUF) process has been used for the removal of copper, chromate, zinc, nickel, cadmium, serinium, arsenate and organics like phenol, o-cresol. This paper reviews various factors such as operating pressure, surfactant concentration, pH of solution, temperature, presence of non-ionic surfactant and salt, membrane type and its pore size and some inhibiting additi...

Micellar-enhanced ultrafiltration (MEUF)-based separation of iron-cyanide complexes, ferriccyanide and ferrocyanide, was investigated in order to assess the potential of MEUF for the removal of ferriccyanide and ferrocyanide with a cationic surfactant, cetylpyridinium chloride (CPC). The removals of ferriccyanide and ferrocyanide were >99% and 99%, respectively, with the molar ratio of CPC to f...

Micellar Enhanced Ultrafiltration (MEUF) of different phenolic derivatives including para-coumaric acid, vanillic acid, and tyrosol, in aqueous solutions has been studied. The MEUF experiments were conducted using an anionic surfactant, namely, Sodium Dodecyl Sulfate (SDS). Two polyethersulfone membranes with different molecular weight cut-off (20 kDa and 50 kDa) were used. Experiments were con...

Micellar-enhanced ultrafiltration (MEUF) of zinc ions (Zn2+) from aqueous solutions using single anionic surfactant sodium dodecyl sulphate (SDS) at low critical micelle concentrations (cmc) (0.2×cmc – 3×cmc) was investigated. When the initial SDS concentration was below the cmc, unexpectedly high rejection (97.5%) was obtained due to concentration polarisation occurring near the membrane-solut...

Micellar-enhanced ultrafiltration (MEUF) was used to remove phenol from simulant aqueous solutions. The effect of groups difference of cationic surfactant on the solubilization of phenol was investigated through orthogonal experiment, namely, surfactants with the same length of hydrocarbon chain but different hydrophilic head group and vice versa. The effects on the solubilization of

In the present study, micellar-enhanced ultrafiltration (MEUF) was used to remove manganese (Mn) (II) from synthetic wastewater. The effects of different operational conditions on the filtration performance of MEUF or the membrane were studied. It was found that the transmembrane pressure has a major influence on the permeate flux and an insignificant effect on the rejection coefficient. The pe...

Simultaneous recovery of copper and DCA from simulated MEUF concentrated stream was investigated. Effects of surfactant (DCA) and metal (copper) concentrations, surfactant to metal molar ratio (S/M ratio), electroplating voltage, EDTA concentration, solution pH, and salt concentration on metal recovery and current efficiency were studied. Electric voltage of -0.5 V was shown to be optimum opera...

this paper presents the development of a model for evaluating adsorbable organic halogens’(aox) removal efficiency during wastewater treatment by using the micellar-enhanced ultrafiltration (meuf)technique. surfactants can form larger aggregates (micelles) were prepared into which aoxs dissolve and arethen retained by the membrane. synthetic wastewater samples containing certain concentrations ...
