Abstract
The results showed that pre-ozonation improved the biodegradability and reduced the acute toxicity. Acute toxicity in raw wastewaters was reduced by 80-90% using 129-200Â mg/L transfered ozone (TrO3) concentrations. At this point, 86-96% of color, 33-39% of soluble COD and 57-64% of total COD were removed from wastewaters. Both color and COD parameters were found related to the acute toxicity of the wastewater. Pre-ozonation decreased the inert soluble COD fraction (SI) of raw wastewater while soluble product formation (SP) increased slightly (5-10Â mg/L). However, residual COD (the sum of SI and SP) remained below discharge limit.
