Abstract

This study investigates the effect of ultrasonic technique (US -20 kHz) pre-treatment, of cow manure (10% T.S.) on biogas production with up-flow anaerobic sludge blanket (UASB).  Ultrasonic accelerates the breakdown of organic matter. Tow UASB prototypes were established: one is attached with a US unit, and the other serving as a control, with varying exposure durations (10, 20, and 30 minutes) and power levels (50, 100, and 150W). The results indicate that ultrasonic pretreatment significantly enhanced biogas production, reaching up to 478.55% over control at ultrasonic 150 watt, time 10 minute. For exposure power levels of UP50T30, UP100T30, and UP150T30, the cumulative biogas production increased by 172.22, 433.18, and 394.91%, respectively compared to control. Data indicated that increasing exposure power from UP50 to UP100 increase in cumulative biogas production, meanwhile, cumulative biogas production decreased by increasing exposure power from UP100 to UP150. However, increasing power to 150 W resulted in a decline in biogas output, indicating a potential negative effect on higher power levels. At low power, extending exposure times (from 10 to 30 minutes) resulted in increases in total biogas generation by 30.82%, 85.40%, and 172.22%, respectively, over control. At medium power, biogas production improved with longer exposure times. Conversely, at high power, increasing exposure from 10 to 20 minutes decreased cumulative biogas output from 37.49 to 31.80, a slight increase to 32.07 liters at 30 minutes. These findings demonstrate while ultrasonic pretreatment can enhance biogas production, increasing the energy level over time leads to decreased production.
