Conditioning of sewage sludge by Fenton's reagent combined with skeleton builders

► A novel joint usage of Fenton's reagent and skeleton builders was investigated. ► Fenton's reagent and skeleton builders are referred as F-S composite conditioner. ► The research focuses on F-S conditioner's efficacies and operational parameters. ► The F-S conditioner can reduce SRF of sludge effectively at a lower dosage.
