“…The cellulose acetate membranes for treatment of leather effluent showed a permeate flux of 33-42.0 Lm -2 h -1 along with separation of suspended and dissolved solids, chlorides, sulphate, oil and grease, ammonical nitrogen, potassium and sodium by more than 80% (Jarvis and Wagener, 1995;Mahendran et al, 2000). PES UF flat membranes on the industrial scale are considered to be technically and economical feasible for treatment of leather and distillery effluents (Huang et al, 1994). Ultrafiltration has wide application in the recovery of milk solids (Briao and Tavares, 2012) and disposal of effluents from dairy waste water (Namvar Mahboub and Pakizeh, 2012).…”

-In this study polyethersulfone ultrafiltration membrane were prepared with the modifier gelatin at 0, 5, 10, 15 and 20 wt % using DMF as solvent by phase inversion process. Morphologies and characteristics of the membranes were investigated through the methods of SEM, XRD, contact angle measurements. The performance of the modified membrane for the treatment of leather and distillery wastewater through a deadend ultrafiltration process was studied. Morphological investigation showed that the 10% gelatin content in 90% PES results in a two layer structure with a porous top and homogeneous sub-layer with uniform number of pores on the surface. The pure water flux of the modified membrane increases with gelatin concentration, which results in better permeation for both leather and distillery wastewater. In addition to 80-90% reduction in BOD and COD, all modified PES UF membranes showed moderate removal of total suspended and dissolved solids, chlorides, sulphate, oil and grease, potassium, sodium and ammonical nitrogen, apart from color removal.

“…Micellar-enhanced ultrafiltration (MEUF) has been used for the ionic pollutants from aqueous streams [13][14][15][16][17][18][19][20][21][22][23]. It combines the high rejection of reverse osmosis with the higher flow rate of ultra filtration.…”

“…Clearly, this may increase the cost of the separation process and/or make the process effluent unacceptable on environmental grounds (Aoudia et al 2003). Huang et al (1994) reported that two important parameters controlled the removal efficiency of metals: surfactant concentration and surfactant to metal molar ratio (S/M ratio). To achieve maximum metal removal efficiency (>99% for most of the metals investigated), the surfactant concentration has to be higher than the CMC of the surfactant (Fillipi et al 1998).…”

Micellar-enhanced ultrafiltration (MEUF) is an effective separation technique for removing metal ions from aqueous environments. The critical micellar concentration (CMC) of two anionic surfactants, sodium dodecyl sulfate (SDS) and linear alkylbenzene sulfonate (LAS), was determined by means of conductometry. The effects of pH, conductivity, and surfactant concentration on the permeate flow, retention of surfactants and nickel by MEUF, was studied. Results showed that for surfactant concentrations beyond the CMC, Ni(II) retention with SDS was slightly higher than with LAS (S/M=45: Ni(II) retention was 70% and 55% for SDS and LAS, respectively). LAS surfactant was always retained in higher quantities than SDS. An increase in conductivity produced large reduction in Ni(II) retention and slightly increased surfactant retention. pH values between 4 and 8 did not affect nickel retention but enhanced the SDS and LAS surfactant retentions.
