With increasing alkalinity, sludge becomes more surface active and has an increasing propensity to foam. Operational conditions that result in an increase in alkalinity include the following:
• Increased alkalinity loading (ionized ammonia, amino acids, proteins, and cationic polyacrylamide polymers) in the digester feed sludge
• Death and lysis of large numbers of bacteria, especially Nocardioforms, resulting in the release of numerous biosurfactants
• Decrease in the destruction of alkalinity within the anaerobic digester (e.g., decrease fatty acid production)
