- •
Effects of short-time aerobic digestion on EPS and sludge features were ascertained.
- •
Both EPS concentration and sludge floc size increased with extending digestion time.
- •
Sludge settleability gradually became poor during the aerobic digestion process.
- •
Short-time aerobic digestion could promote sludge flocculability and dewaterability.
- •
Sludge features showed close relations to proteins and polysaccharides in EPS.
