ULTRASONİK SES DALGASI ÖNİŞLEMİ UYGULANARAK ORGANİK ATIKLARDAN BİYOGAZ ÜRETİMİNİN İNCELENMESİ
INVESTIGATION OF BIOGAS PRODUCTION FROM ORGANIC WASTES BY APPLYING ULTRASONIC SOUND WAVE PRETREATMENT

Summary/Abstract: Various preptreatment technologies have been developed for the production of biogas from lignocellulosic components. One of these pretreatments is the ultrasonic sound wave. In this study, ultrasonic sound waves were applied to organic materials before the production of biogas by anaerobic fermentation. These organic wastes are corn silage (MS) and cattle manure (SG). First, the optimum mixing ratio of MS and SG for anaerobic fermentation was studied. This ratio is by mass MS: SG; 1: 2. Then, ultrasonic sound wave pretreatment was applied to the organic wastes mixed in this ratio. Ultrasonic sound wave intensity was applied at 20 kHz frequency as 5, 15, 30, 50 and 100 kj / gsolid matter. The maximum biogas production was performed at 375.1 ml biogas / g solid matter in the reactor with 30 kj / gsolid matter of substance.
