- •
Effects of various HRTs on the SSMBR performance were investigated.
- •
Shorter HRT aggravated cake layer formation and pore blocking.
- •
SMP was not the influencing factor to membrane fouling at different HRTs.
- •
Increased SMPP/SMPC ratio of mixed liquor resulted in less fouling potency.
- •
Gemfloc® addition could sustain the performance of SSMBR with minimized fouling.
