Abstract
Ozonation of textile industrial wastewaters was examined in CSTR and b atch studies. Experiments were done for various types of textile waste waters and for different reaction and retention times. Much better res ults were obtained using ozonation after the coagulation-precipitation stage. Also a mathematical model was developed, able to describe wast ewater decolorization and COD reduction. In all cases the comparison b etween the model predictions and the experimental data was satisfactor y.
