Multistage treatment of industrial ethylene glycol (EG) effluent: integrating chemical extraction, coagulation/precipitation, and decolouration for enhanced wastewater remediation

Key Points

• Enhanced wastewater remediation reduces ethylene glycol levels significantly, aiding environmental protection.
• The treatment process successfully combines chemical extraction with coagulation and decolouration for optimal results.
• Integrated method shows average removal efficiencies of up to 90% for ethylene glycol in laboratory effluents.
• Finding may enable development of more effective strategies for industrial wastewater treatment, enhancing sustainability.
