Decolorization of reactive dye solutions by electrocoagulation using iron electrodes

摘要

The textile industry is facing major problems in the disposal of wastewater generated from textile dye andudfinishing processes. Textile dye wastewater has a strong colour, high COD, high total solids and is alsoudbiorefractory in nature. There is a need for most suitable and effective pretreatment technique. The presentudwork focuses on the feasibility of electrocoagulation for the reactive dye solutions. The experiments wereudconducted for the optimized electrolysis duration at different applied currents and pH. The Study revealedudthat at a neutral p
