A novel 3D-printed concave photoreactor combined with a photocatalytic membrane effectively removes micropollutants like tetracycline from water. This system achieves over 99% removal efficiency under sunlight, offering a sustainable solution for water treatment.
Area of Science:
- Environmental Science
- Materials Science
- Chemical Engineering
Background:
- Micropollutants in aquatic environments present significant risks to human health.
- Advanced photoreactor and photocatalyst designs are crucial for efficient micropollutant degradation.
Purpose of the Study:
- To design and evaluate a novel flow surface concave photoreactor integrated with a single-atom modified Cr-Bi3O4Br/PVDF photocatalytic membrane.
- To investigate the photo-driven removal of antibiotics at environmentally relevant concentrations.
Main Methods:
- Fabrication of a 3D-printed concave photoreactor to enhance light collection.
- Development of a Cr-Bi3O4Br/PVDF photocatalytic membrane for pollutant degradation.
- Testing the system's efficiency in removing tetracycline (TC) under various conditions, including natural sunlight.
Main Results:
- The system achieved a 99.9% removal rate for 100 ng L-1 tetracycline (TC).
- Under natural sunlight, 99% TC removal was observed over 5000 mL with a flow rate of 1.68 mL/min.
- The photocatalytic membrane facilitated contact between pollutants and hydroxyl radicals, enhancing degradation.
Conclusions:
- The synergistic effect of the 3D-printed concave photoreactor and photocatalytic membrane provides an effective strategy for sunlight-driven micropollutant removal.
- This work offers valuable insights for designing advanced water treatment equipment.
