Abstract
The effect of three sludge treatment processes (heat treatment, anaerobic digestion and anaerobic digestion with polymer addition) on the fate (i.e., mass in the solid and liquid fractions) and leachability of trace organic contaminants in a municipal wastewater treatment plant sludge was evaluated. In general, heat treatment was found to be the most effective method for reducing both total contaminant mass and leachability, whereas digestion with polymer addition was the most effective for reducing contaminant mass in the liquid fraction.
