Disintegration of waste activated sludge by different applications of Fenton process

- Conventional and Fenton-type processes were studied for the disintegration of WAS.
- Fenton-type process with ZVI was as effective as conventional Fenton process.
- The sludge disintegration was happened in 2 stages: rapid and slow disintegration.
- Rapid disintegration stage was described as zero-order kinetics model.
- Both processes improved the methane production and anaerobic digestion.
