Treatment of Acid Red 73 wastewater by the O3/RSR-BCR process

Rotor-stator reactor (RSR) was employed in tandem with bubble column reactor (BCR) to enhance Acid Red 73 (AR73) degradation by ozonation in a simulated dyeing wastewater in this work. It was found that AR73 and COD degradation efficiencies of more than 97 % and 30 % respectively were achieved in the O3/RSR-BCR process. Due to the excellent mass transfer effect of RSR, AR73 degradation efficiency in the O3/RSR-BCR process was significantly...
