In quest of environmental hotspots of sewage sludge treatment combining anaerobic digestion and mechanical dewatering: A life cycle assessment approach
Hotspots on sludge treatment are assessed thanks to parameter sensitivity analysis. VS biodegradation and N mineralization rates are sensitive parameters for AD. P and N capture rates are sensitive parameters for thickening and dewatering. FeCl3 consumption is a sensitive variable for conditioning process prior dewatering.
