- •
The dewatering of digestate performance was effectively improved by conditioning jointly with CTAB and coal fly ash.
- •
The relationship between dewaterability of digestates and the extracellular polymeric substances, particle size, and surface charge was obtained.
- •
The mechanism of the in-depth digestate dewatering was inferred and the factors were determined to be critical.
