Effects of Electrodialysis Physical and Operating Parameters on the Performance of an Anaerobic Digestion-Electrodialysis System for Volatile Fatty Acid Production and Recovery.

ABSTRACT: Anaerobic digestion (AD) has two key challenges for producing volatile fatty acids (VFAs) from organic-rich wastes: (i) VFA production can become inhibited by VFA/NH₄ ⁺ accumulation, and (ii) VFAs must be selectively recovered. To address both challenges, VFAs and NH₄ ⁺ must be separated from the AD digestate, which has been previously accomplished using electrodialysis (ED) as a separation method. Previous studies have validated the technical feasibility of combining AD and ED to enhance VFA production and recovery but only for cases using one ED configuration. Therefore, the role of ED physical and operating parameters, which govern VFA/NH₄ ⁺ concentrations in the ED-treated digestate that is recycled back to the AD biorea
