Evaluation of operational parameters for semi-continuous anaerobic digester treating pretreated waste activated sludge

Experimental analysis of citric acid and bacterial pretreatment on waste activated sludge (WAS) was performed in a semi-continuous anaerobic reactor for assessing the sludge reduction. The sludge pretreatment was carried out by deflocculating the WAS using 50 mM/L citric acid and subjecting to bacte...
