Denitrification of a wastewater containing 36,000 mg/L NO 3 − (8,200 mg/L NO 3–N) with ionic strength of 3.0 has been achieved using activated sludge in bench-scale sequencing batch reactors. An activated sludge culture was acclimated to denitrify the wastewater at pH 9, by step-wise increase in was...
