Ultrasonic disintegration is a method for breakup of microbial cells to extract intracellular material. Ultrasound-activated sewage sludge disintegration could positively affect anaerobic digestion of sewage sludge at sewage treatment plants (STPs). Due to sludge disintegration, organic compounds are transferred from the sludge solids into the aqueous phase resulting in an enhanced biodegradability. Therefore disintegration of sewage […]
