Phenol and Ammonia Recovery. Finally, the closely related passive and fa-cilitated-transport processes for phenol and ammonia recovery should be mentioned. In these processes, dilute phenol or ammonia feed solutions are contacted with a liquid membrane in which they are freely soluble. They dissolve in the membrane, diffusing to the product side where they are removed by neutralizing with a base (in the case of phenol) or an acid (in the case of ammonia). Although the transport mechanism does not involve a carrier and these are, therefore, passive transport processes, the actual process is quite similar, and Li et al25 published the details of these separations using emulsion membrane technique. 

Enhancement of gravity settling by electrophoresis is also used with liquid-liquid dispersions in solvent extraction and for the separation of oil-water emulsions. Electro-osmosis on its own is a well-tested method for the gathering of ground water to facilitate its removal from foimdations and other sites in civil engineering. It can also be applied to the dewatering of filter cakes as described in the following. 

There is an ever increasing interest in the use of liquid membranes for performing chemical separations. Emulsion liquid membrane (ELM) systems in which the targeted chemical species in an aqueous solution is extracted with a multicomponent emulsion have a variety of applications. These include isolation and concentration of valued or harmful substances in industrial chemistry, separation of substances for determination in analytical chemistry, separation of pollutants in environmental remediation, and detoxification of biological fluids by removal of harmful substances of exogenic and endogenic origins (7). 

Experimental Measurements. Removal of arsenic firom metallurgical wastewater by emulsion liquid membrane was studied experimentally (9). One set of experimental data is used here to verify the mathematical model. The experiment on emulsion liquid membrane removal of arsenic was conducted as follows.
