Simultaneous anammox and denitrification (SAD) process in sequencing batch reactors

•Simultaneous anammox and denitrification (SAD) process was simulated by using SBRs.•The SAD process was demonstrated in SBRs fed with ammonium, nitrate, and acetate.•Nitrogen removal in the SBR remained high for a long term in wide C/N ratios.•The anammox contribution to nitrogen removal was high a...
