Effect of ultrasonic on sludge solubilisation and anaerobic biological digestion

Anaerobic digestion is the standard technique to treat the biological sludge with the benefits of mass reduction, methane production and improved dewatering properties of the fermented sludge. Due to the rate-limiting step of sludge hydrolysis, anaerobic degradation is a slow process with typical digestion time of 20 or more days (Eastman and Ferguson, 1981), and hence, large digesters are necessary.
