Effect of Mn2+ augmentation on reinforcing aerobic sludge granulation in a sequencing batch reactor

Abstract

Two sequencing batch reactors were synchronously operated to investigate the effect of manganese (II) (Mn2+) augmentation on aerobic granulation. Reactor 1 (R1) was added with 10 mg/L Mn2+, while there was no Mn2+ augmentation in reactor 2 (R2). Results showed that R1 had a faster granulation process than R2 and R1 performed better in chemical oxygen demand… (More)
