Integrated oxygen-limited sequencing batch biofilm reactor (SBBR) process coupled with iron‑carbon micro-electrolysis: Simultaneous nitrogen and phosphorus removal performance and mechanism

Key Points

• Nitrogen and phosphorus removal performances improved significantly with the use of iron-carbon micro-electrolysis,
• The process achieved an effective removal rate exceeding 90% within 24 hours of operation in wastewater samples.
• Assessment through an integrated oxygen-limited sequencing batch biofilm reactor highlights innovative treatment mechanisms involving biofilms.
• The findings suggest potential for improved wastewater treatment solutions, enabling better nutrient management in aquatic environments.
