The main objective of the disintegration of sewage sludge is to obtain a greater susceptibility of sludge on subsequent biotechnological processes. In order to determine the best parameters of the disintegration of excess sludge examined, the effectiveness of hybrid methods, i.e. thermal disintegration aided ultrasonic disintegration. Support thermal method by disintegration by active operation of the ultrasonic field results in high efficiency of the process, estimated by disintegration degree of hybrid modified sludge. Based on the obtained disintegration degree in the excess sludge after the individual thermal method (60 °C, time of heating 3 h) and thermal-ultrasonic method (60 °C, 3h and acoustic power of 214.21 W, sonication time 600s) a significant i.e. 35.98% increase in the disintegration degree of hybrid modified sludge was observed.
