Biological treatment of red bronze dye through anaerobic process

Industries that are ever increasing are major contributors to environmental pollution due to inappropriate waste handling. Textile wastewater contains mutagenic and carcinogenic chemicals which are harmful to natural phenomenon of receiving water channels. Therefore, textile wastes should be treated before discharging in the environment. Treatment of red bronze dye was investigated in the upflow anaerobic bioreactor. Varying dye concentrations (40~325 mg/L) were treated by adjusting primary pH at neutral. The performance of reactor was judged by conventional process parameters like pH, turbidity, dissolved oxygen (DO), electroconductivity (EC), total dissolve solids (TDS), removal efficiency, and chemical oxygen demand (COD). The maximum removal efficiency occurred at 150 mg/L dye concentration with addition of 50 ml of biomass. The pH of the water remained basic, COD removal ranged between 60 and 91%, and the maximum removal was done at 91%. EC and TDS were also low indicating good dye removal efficiency of the reactor.
