Biodegradability assessment of ozonated raw and biotreated pharmaceutical wastewater

The activated sludge specific oxygen uptake rate (SOUR) and BOD(5)/COD ratios of biologically pretreated pharmaceutical wastewater were analyzed and compared to assess relative changes in biotreatability during ozonation at a rate of 7.4 g/(L x h) for 4 h. An appreciable COD removal (41%) was achiev...
