Developing an Integrated Treatment Technology Based on Electrocoagulation, Electroflotation, and Electrooxidation

Key Points

• To develop an integrated electrochemical technology for effective industrial wastewater treatment.
• Developed a system combining electrocoagulation, electroflotation, and electrooxidation processes for wastewater.
• Utilized metal hydroxide coagulants generated in situ during electrocoagulation to destabilize contaminants.
• Implemented electroflotation to enhance the separation of solids through gas bubbles that remove flocs.
• Applied electrooxidation to target residual organic compounds and improve effluent quality.
• Successfully demonstrated enhanced removal of colloids, emulsions, and dissolved metals.
• Achieved improved separation of solids leading to better wastewater clarity.
• Showed significant reduction in refractory organic matter, enhancing potential for effluent reuse.
