Increasing biogas production from maize silage by ultrasonic treatment

Popis výsledku v původním jazyce

Maize silage is one of the most commonly used substrates in biogas plants. However, a considerable part of it is not biologically converted into biogas during anaerobic digestion process (AD). Cavitation induced by ultrasonic treatment of substrate causes increase of particles' specific area, cell lysis and sonochemical reactions, resulting in splitting of complex organic compounds due to formation of radicals. As a consequence, faster and more efficient conversion of substrate into methane is achieved.To evaluate effect of sonication on biogas production, parallel batch experiments in CSTR bioreactors were carried out. Assessment of substrate disintegration caused by sonication was based on measurements of Chemical oxygen demand (COD) in liquid phaseof substrate samples. The biogas and methane yields were determined by continuous measurement of biogas flow rate and composition. The resulting biogas production enhancement was 13 - 29.5%, methane yield was increased by 16.9 R
