Description of key information

>99.9% removal; 93% by biodegradation and 7% stripped (volatilized) from the wastewater.

Key value for chemical safety assessment

Additional information

The biodegradation of ethyl acetate has been studied in continuous flow activated sludge reactors.  Biodegradability over 6 days was evaluated by ultimate BOD analysis compared to TOC and COD values. The ultimate treatment efficiency for ethyl acetate was 99.9% removal; 93% by biodegradation and 7% stripped (volatilized) from the wastewater. There was no sorption to sediment.  Hydraulic retention time in the reactor was 8 hours.
