Effect of pH adjustment on the liquefaction process of anaerobic digestate and seed germination

This study aimed to survey the chemical change and germination effect of anaerobic digestate after pH adjustment aerobic treatment. The amount ammonia (NH3) in swine slurry digestates (SS AD) 7.0 6.5 were lower than that un-adjusted digestate. Especially, with had lowest NH3 generation. NH4-N has been gradually decreasing untreated digestate, however, showed no significant changes. In tests different methods, index (GI) was higher Thus, will be useful decrease gas generation such as NH3, which causes odor generated from
