Although textile dyes is basically available in very low concentration (10-200 ppm); it should be removed due to the toxicity to human body and environment. Among the existing methods, emulsion liquid membrane (ELM) is a promising method by providing high interfacial area and the ability to remove a very low concentration of the solute. The optimal emulsions were produced using commercially supplied homogeniser. Initially, methylene blue in simulated wastewater was extracted using a Taylor-Couette column. Methylene blue concentration was determined using spectrophotometer. Complete extraction was performed in the designed column. The research obtained optimal extraction efficiency of about 99% at external phase pH of 10, carrier concentration of 9 wt.%, HCl concentration of 0.5 M, initial feed concentration of 20 ppm, volume ratio of emulsion to feed phase of 1:5, extraction time of 5 min, and extraction speed of 600 rpm. © 2018, Penerbit UTM Press.
