Study on the application of Taylor-Couette column for emulsion liquid membrane system has been done. To optimise extraction process under TCC, a research to investigate effect of viscosity and cylinders rotation is of important. Fluid viscosity was examined by varying volume ratio of kerosene to water. TCC was characterised to determine flow regimes, shear stress, and energy loss distribution. Volume ratio of oil to water was varied at 1:1, 1:3, 1:5, and 1:6 while inner and outer cylinders speed were maintained constant at 300 and 200 rpm, respectively. Investigation on the effect of volume ratio of oil to water towards flow regime ended to same flow regime of Featureless Turbulent. There was degradation of wall shear stress from 8.57x10-2 Pa to 7.42x10-2 Pa.

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.

High demand on batik fabric significantly increased wastewater volume from batik home industries. Copper, being used as mordanting agent, available in the highest concentration in industrial textile wastewater. Emulsion liquid membrane (ELM) is promising selective method to recover solute. Taylor-Couette column (TCC) was proposedtoextractcopperinsteadofusingconventionalreactorthatdisturbsemulsion stability. Experiment was done by varying volume ratio of emulsion to feed phase, carrier and internal phase concentration. Extraction efficiency of>98% was obtained at volume ratio of emulsion to feed phase of 1:5, carrier concentration of 4 wt. %, and internal phase concentration of 0.1 M, respectively
