In order to investigate the enhancement of combination of ultrasound process and ozonation for the removal of aqueous tannin, tannin concentration, chemical oxygen demand (COD), and total organic carbon (TOC) were analyzed in ultrasound process, ozonation, and ultrasound/ozone process. Even though ultrasound process was not effective for the removal of aqueous in terms of tannin concentration, COD, and TOC, ultrasound process could enhance the removal efficiency significantly when it was combined with ozonation. It was also revealed that COD removal resulted in partly mineralization due to insufficient oxidation power, which was induced by ultrasound and ozone. However average oxidation state of all organics in the solution was increased cogently and as a result, biodegradability could be increased meaningfully. Therefore ultrasound/ozone process could be effective pre-treatment process to biological process for the removal of aqueous tannin.
