Electro Oxidation and Biodegradation of Textile Dye Effluent Containing Procion Blue 2G Using Fungal Strain Phanerochate Chrysosporium MTCC 787

Abstract

Biodegradation experiments were carried out using the fungal strain Phanerochate chrysosporium MTCC 787 to reduce the chemical oxygen demand (COD) and the color of the textile effluent containing Procion Blue 2G.In degradation, biochemical oxidation (BO) was coupled with an electro oxidation (EO) process before and during sequence. The integrated process was carried out in three cycles for the effluents containing 10 mL and 20 mL of inoculum (two different culture concentrations) in aerobic conditions. The overall COD reduction was 90.6% and 92.4%, respectively, and complete color removal was achieved at the end of sequential integrated oxidation process. The treated effluent was subjected to photo-oxidation to remove the microbes so that the water can be recycled after the removal of total dissolved solids (TDS).The experimental results showed that the integrated BO with EO is a viable option to reduce COD and color of the dye solution containing the bio-recalcitrant reactive dye Procion Blue 2G using the fungal strain Phanerochate chrysosporium MTCC 787.
