Siphon-driven tidal flow enhances pyrene removal in iron-based baffled constructed wetlands: Feasibility and mechanism

Key Points

• Enhanced pyrene removal was observed with siphon-driven tidal flow, indicating a significant increase in efficiency.
• Pyrene levels decreased by 30% using iron-based materials in the constructed wetlands during the experiment.
• Assessment using siphon-driven tidal flow and baffled constructed wetlands showed improved contaminant management.
• Findings suggest the potential for using this method in similar environmental remediation efforts.
