In this study, textile finishing wastewater was treated with Fenton's reagent
(hydrogen peroxide-ferrous iron system). Under unstable and complex
wastewater condition, Fenton's reagent was unable to comply with the standard
set by the authority with respectto COD. However, removal of SS complieswith
. the standard while visibility of the wastewater improves by more than 50 %.
Removal was mainly by DB radical oxidation as compared to hydroxide
precipitation. . Mineralisation of more than 50 % organics was observed after 5
min.utes reaction while 77 % mineralisation was observed aft.er 30 minutes
reaction. The amount of hydrogen peroxide and ferrous iron substantially affects
the quality of the treated wastewater.
