COD and nitrogen removal in facilitated transfer membrane-aerated biofilm reactor (FT-MABR)

► Designing a facilitated transfer membrane-aerated biofilm reactor (FT-MABR). ► Exploring the effects of feed flow velocity on COD, NH4+-N and TN removal. ► Discussing the effects of facilitated transfer on the bacteria's growth and competition of oxygen. ► Analyzing the shortcut denitrification in the FT-MABR.
