The methylene blue and dyestuff removal efficiency in a textile factory by ozonation and/or carbonaceous material treatment was investigated. Three kinds of carbonaceous materials were prepared from wool(WL), polyester(PET), and cotton(CT)discharged from the textile factory. The physical properties of the carbonaceous materials were very different. The specific surface area and pore volume of WL were the lowest, while those of CT were the highest. The dyestuff removal efficiency from actual dyestuff water was the highest when using the carbonaceous material(CT)prepared from cotton waste fiber. The decreases in the chromaticity, turbidity, COD, and TOC of the actual dyestuff wastewater depended upon the mean pore diameter of the carbonaceous material. The COD and TOC of the actual dyestuff wastewater were only slightly decreased by ozonation. The ozonation with CT would be useful for the removal of the dyestuff from actual textile wastewater. These results indicated that the waste cotton fiber could be converted into a carbonaceous material as an adsorbent for the removal of dyestuff from actual wastewater.
