Overview

Demonstrates effective PFAS degradation in polymer manufacturing wastewater, suggesting metal enhancement boosts treatment efficiency.

Key Points

  • The study aims to evaluate anaerobic treatment of polymer manufacturing wastewater containing PFAS and assess the impact of catalytic metals.
  • Utilized an anaerobic reactor to treat complex wastewater from a polymer factory.
  • Investigated the catalytic effect of recovered metals on reactor performance.
  • Measured organic matter removal linked to methanogenesis and sulfate reduction.
  • High chemical oxygen demand (COD) removal was achieved, with metal-enriched reactor showing 59% COD removal.
  • Methanogenesis and sulfate reduction were significant processes in treatment.
  • Metal enrichment led to enhanced defluorination of PFAS, producing twice as much fluoride compared to the control.
