Treatment of petroleum wastewater by electrocoagulation using recycled aluminum from cans as electrodes: optimization of operating parameters by Box–Behnken design

Key Points

• Improved wastewater treatment is achieved through optimized electrocoagulation processes.
• Using recycled aluminum electrodes shows a significant reduction in petroleum content.
• Optimization was conducted through a Box-Behnken design for operating parameters.
• Results support effective use of recycled materials in environmental remediation efforts.
