Improvement of colour and cod removal in molasses wastewaterby using advanced oxidation processes
In order to improve color and chemical oxygen demand (COD) removal in molasses wastewater, chemical and biological methods were combined. Advance oxidation techniques, Fenton's reagent oxidation and ozonation, were used for pretreatment of molasses pigment solution before Chlorella saccharophil...
