Abstract: This study examines degradation of syntan (synthetic tannin) using ozonation process. Ozonation of syntan (initial conc.100 mg/l; ozone dose, 1 g/h) showed removal of COD (91%), tannin (98%) and UV absorbance (99%) at pH 7. A significant BOD5/COD ratio variation (0.21-0.29) at pH 7 confirmed that ozonation is an effective
