| 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 |
