Agricultural Anaerobic Digesters Design and Operation

Due to the microbial process occurring in two definite steps the acidforming and the methaneforming stages it has been suggested by Jewell et al 1974a that a twostage digester should be more efficient than a singlestage unit In this way each stage could be controlled for maximum efficiency of each group of bacteria

Effect of Effluent Recirculation on Biogas Production

Citrus waste is a promising potential feedstock for anaerobic digestion yet the presence of inhibitors such as dlimonene is known to limit the process Effluent recirculation has been proven to increase methane yield in a semicontinuous process for recalcitrant material but it has never been applied to toxic materials This study was aimed to investigate the effect of recirculation on
