Treatment of refinery spent caustic wastewater using electro-fenton/adsorption hybrid process

Key Points

• The hybrid process significantly reduces contaminants in refinery spent caustic wastewater, enhancing treatment efficiency.
• A reduction of over 90% in chemical oxygen demand indicates robust performance of the electro-fenton method.
• Assessment using a hybrid electro-fenton and adsorption treatment method shows promising results for wastewater management.
• This technique highlights the potential for effective refinery wastewater treatment, but large-scale application remains to be validated.
