Abstract

This study examines the impact of microwave technique (MW) pretreatment, microwave treatment accelerates the breakdown of organic matter, leading to higher biogas production.  (10% TS) of cow manure prior to digestion process in an up-flow anaerobic blanket (UASB) reactor on the biogas production. A microwave pretreatment unit was established alongside two UASB prototypes: one connected to MV unit and the other serving as control. The study analyzed different microwave exposure durations (10, 20, and 30 minutes) and intensities (270, 450, and 630W). Results showed that microwave pretreatments significantly enhanced biogas production compared to the control, with a remarkable 569.30% increase at 20 minutes,450 watt. Cumulative biogas yield varies with exposure durations and power levels. At low power, increasing exposure time from 10 to 30 minutes improved biogas output; similarly, at medium power, extending exposure time from 10 to 20 minutes raised biogas production, while extending to 30 minutes resulted in decreasing biogas production. At high power, extending exposure time from 10 to 20 minutes reduced biogas production, however a slight non-significant increase was observed when extending from 20 to 30 minutes. Increasing power levels significantly affect output, at 10 minutes, higher power level led to more daily biogas production, and similar trends were observed at 30 minutes. Specifically, raising power from 270 to 450 watts results in a 42.48% rise in cumulative output, while increasing from 450 to 630 watts led 9.1% decrease. Therefore, while raising power levels initially boosts biogas production, excessive increases lead to a decrease in the biogas production.
