- Ultrasonic disintegration is one of the most interesting technologies among all known and described technologies for sewage sludge pre-treatment before the process of methane fermentation. This study was aimed at determining the effects of an innovative ultrasonic string disintegrator used for sewage sludge pre-treatment on the effectiveness of methane fermentation process. In this experiment, we used a device for disintegration of organic substrates, including sewage sludge, with the use ultrasonic waves. Its technical solution is protected by a patent no. P. 391477 – Device for destruction of tissue and cell structures of organic substrate. The volume of biogas produced ranged from 0.194±0.089 dm3/g o.d.m. at loading of 5.0 g o.d.m./dm3 and power of 50 W to 0.315±0.087 dm3/g o.d.m. at loading of 4.0 g o.d.m./dm3 and ultrasounds power of 125 W. The study demonstrated a positive effect of sewage sludge sonication on the percentage content of methane in biogas. Sewage sludge exposure to 125 W ultrasounds increased methane content in biogas to 68.3±2.5 % at tank loading of 3.0 g o.d.m./dm3.
