Evaluation of Fenton method and ozone-based processes for colour and organic matter removal from biologically pre-treated swine manure.

This work evaluates the efficiency of different advanced oxidation processes (Fenton method, O3 ,H 2O2 and O3/H2O2) for removing total COD (TCOD) and colour from biologically pre-treated swine manure. The Fenton process with a dosage of 100 mg L 1
