Decolorization of Reactive Dye Solutions by Electrocoagulation using Iron Electrodes

The textile industry is facing major problems in the disposal of wastewater generated from textile dye and finishing processes. Textile dye wastewater has a strong colour, high COD, high total solids and is also biorefractory in nature. There is a need for most suitable and effective pretreatment technique. The present work focuses on the feasibility of electrocoagulation for the reactive dye solutions. The experiments were conducted for the optimized electrolysis duration at different applied currents and pH. The Study revealed that at a neutral pH there was a colour removal efficiency of 90% with minimum sludge production and anode consumption.
