Résumé

The source diverted blackwater treatment is receiving growing attention as an alternative to conventional energy intensive wastewater management and treatment systems. Blackwater, containing concentrated organic materials, can be anaerobically digested to recovery bioenergy. However, the methane recovery from blackwater is often inhibited by the presence of high free ammonia (FA) in blackwater. In order to improve the methane production in blackwater, nano-scale zero valent iron (nZVI, 35 nm or 50 nm) or micro-scale zero valent iron (mZVI, 200 μm) at different dosages (i.e., 0.5, 1, and 10 g/L) were applied respectively in the anaerobic digestion (AD) reactor for blackwater treatment. The results demonstrated that low doses (0.5-1 g/L) of nZVI slightly improved methane (CH
