The aim of the experiments was to determine the influence of ultrasound disintegration on methane fermentation process efficiency. The experiments were carried out in technical scale at the Agriculture Biogas Plant in Bałdy. The research concentrated on the quantity and quality of biogas produced.

The facility for organic substrate disintegration with ultrasound consists of 5 tubular segments with square crosssections. The size of a single segment is 96 x 96 x 850 mm. The active volume of one segment is 8 liters. Segments are made of acid-proof steel. It cycles automatically, using a circulating pump for feeding and emptying.
Ultrasound disintegrator characteristics: Power: 10 kw Converters: n = 60 Frequency: 24 khz Active volume of disintegrator: 40 l Number of working cycles per day (feeding/disintegration/discharge): 13 Time for a single disintegration cycle (feeding/disintegration/discharge): 30/900/30 s Total time of disintegration: 3.5 h/d Volume of disintegrated substrate: 500 l/d Required daily quantity of energy: 35 kwh/d
