Abstract

Microaeration is a new technology applying on anaerobic digestion (AD) to improve hydrolysis, reduce volatile fatty acids (VFA), enhance methane

production and remove H2S from the biogas. This pepper compared between traditional AD (T1) and microaerated AD (T2). Dosing O2 started in (T2) with(0.07LO2\Lfeed\day) at the  10th day  to the 30th day ( end of the study) , temperature  was set at 35°. AS a result  Microaeration have several positive impact on AD(T2) represented by removing H2S which reached 97.7% after 30 days of treatment ,and increasing CH4 which reached 77.8%(V\v),in addition COD and SO4 was stability  decreased on T2
