Abstract

Bench experiments were conducted to investigate the efficiency of ozonation in removing the color (turbidity) and chemical oxygen demand of the textile waste effluents. It has been observed that six hours of ozonation are sufficient to remove most of the color in the waste effluent and up to 50 percent of its COD. The small molecule organic compounds produced by dye decomposition, which contribute significantly to the final COD concentration in the ozonation process, can be easily degraded in an activated sludge process. Combining ozonation and the activated sludge process can provide a very effective means for dealing with this particular type of industrial waste effluent.
