Description:
The study evaluates the effects of enzyme augmentation on municipal wastewater (MWW) sludge anaerobic digestion. The primary objective was to examine the impact of using enzymes to enhance the degradation of the cellulosic and the oil- and grease-rich sludge fractions. The addition of cellulase enzymes to enhance the anaerobic digestion of the cellulosic component and the addition of lipase enzymes to degrade oil and grease was evaluated in a series of laboratory-scale studies. The results of the program show that cellulase enzyme augmentation can produce a significant enhancement of the anaerobic digestion of municipal wastewater sludge.
