  • Dewatering of sewage sludge via thermal hydrolysis with ...

    Fenton iron sludge can be reused to catalyze the dewatering of SS and to recover its residual energy as a solid fuel. Abstract In this study, the alkaline hydrothermal ferric carbon (AHFC), which was prepared by hydrothermal liquefaction method using Fenton iron sludge with NH 3 H 2 O, was used as a skeleton materials for the dewatering of sewage sludge (SS) via thermal hydrolysis.
