Abstract	1, Introduction Melanoidin is a dark brown colored substance generated by Maillard reaction of amino acids and carbohydrates. The wastewater containing melanoidin discharged from sugar factories seriously contaminates rivers, lakes, and marshes in Southeast Asian countries. It is, therefore, desired to develop a simple and economical technique to treat and to decolorize this wastewater, because of cheapness of raw sugar product and of the economic states of these countries. There have been several studies to treat this wastewater: the absorption of melanoidin by activated carbon 1), the decomposition by ultraviolet ray 2), the removal of melanoidin by foam fractionation 3). Foam fractionation in the last study is a quite convenient separation technique. In this thesis, the continuous operation was applied to the foam fractionation of melanoidin from wastewater. In the first, the effects of operation factors on the performances were studied experimentally. Secondly, the countercurrent multistage foam fractionation process removing melanoidin was synthesized and was simulated with the experimental results.
