文摘
- •
Sludge dewaterability was improved by Fe(II)-PMS with high CST and SRF reduction.
- •
Optimal conditions were identified: PMS 0.9 mmol/gVSS, Fe(II) 0.81 mmol/gVSS, pH 6.8.
- •
The protein in EPS conducted a detrimental influence on sludge dewaterability.
- •
The release of EPS-bound water induced the enhanced sludge dewatering.
