Investigating and Comparing the Feasibility of Using Anaerobic Digesters in Wastewater Treatment Plants with SBR and MLE Processes

Nowadays, due to the decrease in fossil fuel resources, generating biogas from corruptible waste is getting attention. Anaerobic digesters are utilized in wastes management and produce renewable energy from it. Generally, the anaerobic digesters convert wastes to methane and carbon dioxide. Effective parameters on the anaerobic digestion process are reactor configuration, temperature range, mixing system, and waste type. In this paper, using of produced sludge in an anaerobic digester was investigated for municipal WWTP with SBR and MLE processes. For this means, Alteimour and Kheine-Arab wastewater treatment plants (WWTPs) have been considered as case studies. The applied processes in Kheine-Arab and Alteimour WWTPs are SBR and MLE, respectively. Results comparison shows that the produced sludge from the SBR process (Kheine-Arab WWTP) has no suitable potential for biogas production. However, there is potential for biogas production at the Alteimour treatment plant, and investment can be made in the future on Alteimour WWTP.
