Studying Temperature and Loading Rate Effect on Anaerobic Digester Production of Biogas

This research discusses the affecting factors of biogas production in the digester, to define the optimal temperature and suitable loading rate to achieve high digester biogas production. The research focuses on the water compressed continuous flow digester (chines model), and the results is presented and illustrated in suitable tables and curves.

Choosing the Optimal Economic Size of the Batch Closed Digester Providing with Solar Energy During Thermophilic Anaerobic Digestion

This research aims to study the effect of the digester size on its thermal requirements in order to reach the optimal economic size to him. Where were studied a batch closed digester with solar collector, where he was measuring a thermal requirements at the same ambient conditions with the change of the size of this digester, in order to note the relative change of the heat requirements, and to get the optimal size that requires the least amount of energy in thermophilicanaerobic digestion.
