- Abstract
In the present research work comparative investigation for decolorisation of textile effluents by different chemical methods was investigated. One industrial effluent was prepared synthetically and other two were collected from industry. Samples were subjected to three different advance oxidation processes which were Fenton and photo-Fenton. Fenton treatment was optimised with different parameters like concentration of H2O2, pH, dose of Fe2+ and temperature. Then optimised conditions were employed with varying light intensities in photo-Fenton treatment using UV/vis. lamp and at different time intervals of day in solar-Fenton treatment using solar light. The effectiveness was evaluated by water quality assurance parameters such as total organic carbon (TOC), chemical oxygen demand (COD) and total suspended solids (TSS). The maximum decolorisation and mineralisation was obtained with photo-Fenton treatment using UV/Visible lamp which is supported by showing decreases in chemical oxygen demand (COD) and total organic carbon (TOC) of the treated effluents solutions. The Ames mutagenicity testing assay showed reduced mutagenicity of treated effluents by all three treatment technologies in both strains of Salmonella (TA98 and TA100). The results showed the employment studied treatments led to decolorisation and substantial mineralisation of effluents under study, however, photo-Fenton process exhibited a little more oxidation potential than others.
