- •
PACl addition promoted the re-growth of broken flocs regardless of breakage times.
- •
PAM addition only promoted the re-growth of broken flocs at first breakage steady state.
- •
Sweep and bridging generated different floc properties by various attachment modes of broken floc.
- •
Second dose under sweep had reactive function on inactive surface points.
- •
The coverage extent of broken flocs mainly affected floc properties under bridging.
