Filamentous Microorganisms How do they end up in Anaerobic Digesters? Surface wasting and WAS from Aeration Basinsis sent to solids handling How do they produce foam in AnaerobicDigesters? Filamentous bacteria attach themselves onto thebiogas bubbles produced during anaerobicdigestion processes They prosper in anaerobic digesters due to theirability to metabolize hydrocarbons (abundant indigesters)
