Abstract

Oxidation of fabric dyeing wastewater was investigated in supercritical water with CuSO₄/FeSO₄ as catalyst. The effects of various operating parameters like temperature, pressure, hydrogen peroxide concentration and catalyst concentration on the removal of color and COD from wastewater were investigated. The percent removals of color and COD at 450°C, 28MPa using 120% hydrogen peroxide dosage and 2.0mg/L catalyst was 100% and 99%, respectively. Experimental results indicated that CuSO₄ and FeSO₄ had a significant effect on the COD and color removal. CuSO₄ had greater effect on COD and color removal than FeSO₄. The effect on catalyst on color removal has been found to be less in comparison to COD removal.
