An ozone utilization of 0.27 g/g-COD (chemical oxygen demand) lowered the pH of the wastewater to 6.6, reduced the specific ultraviolet absorption by 43% and increased the biochemical oxygen demand (BOD) concentration by 37%. The BOD:COD ratio became equal to 0.89, making the ozonated wastewater seemingly suitable for biological treatment; however, when the ozonated effluent was fed to the SBR, the reactor performance degraded, an effect which was attributed to ozonation by-products. In conclusion, ozonation might not be a suitable pre-treatment for pharmaceutical wastewater containing amoxicillin, and biotreatment with properly acclimated biomass may be a better option for treatment of such pharmaceutical wastewater. © IWA Publishing 2013. | Source Title: | Water Science and Technology | URI: | http://scholarbank.nus.edu.sg/handle/10635/91231 | ISSN: | 02731223 | DOI: | 10.2166/wst.2013.534 |
