Overview

Comprehensive comparison evaluates nitrogen removal and emissions in integrated wastewater treatment systems, suggesting a novel approach for better performance.

Key Points

  • This research aims to compare the efficiencies of two wastewater treatment systems utilizing Integrated Fixed-Film Activated Sludge (IFAS).
  • Comparative analysis of two Lines: Line 1 with ultrafiltration (UF) and Line 2 with Encapsulated Biofilm Self-Forming Dynamic Membrane Bioreactor (EBSF-DMBR).
  • Assessment of carbon, nitrogen, and phosphorus removal efficiencies, N2O emissions, membrane fouling behavior, carbon footprint, and water reuse.
  • Respirometry was performed to evaluate kinetics of both treatment lines.
  • Line 2 achieved significantly higher total nitrogen removal (90 ± 6%) compared to Line 1 (66 ± 18%).
  • Line 2 exhibited lower N2O emissions (0.25 ± 0.10%) and reduced membrane fouling rate (0.004 ± 0.002 bar day -1 ).
  • EBSF-DMBR showed a lower carbon footprint (1.7 kg CO2 eq m -3 ) than Line 1 (2.6 kg CO2 eq m -3 ).
