Two-stage anaerobic digestion using protein-rich synthetic wastewater inoculated with anaerobic sludge

Foam and scum have impacted digestion, causing process disturbances in several industries. The cause of foam and scum is difficult to determine as there are complex compounds in wastewater. Proteins are the primary compound found in food processing industries wastewater. This study investigates the...
