- •
The role of nonsettleable grit in the performance of a MBR was investigated.
- •
The grit in the mixed liquor displayed little influence on nutrient removal.
- •
The grit improved the sludge settleablity and decreased the sludge floc size.
- •
The presence of grit in the mixed liquor increased the membrane fouling rates.
- •
The grit induced significant changes in the bacterial community structure.
