| Abstract: | This article compares multi-stage ozonation-biological treatment processes O3 - Biodegradation - O3 - Biodegradation] and conventional partial ozonation processes O3 - Biodegradation] for the removal of SCOD and toxicity from a recalcitrant and toxic wastewater concentrate. Both direct (pH 7.5) and advanced (pH 11.5) ozonation are evaluated. Short-term estimation methods for biodegradability (respirometry) and toxicity (30 min Vibrio fisheri luminescence inhibition) are evaluated for their use in process control. |
