Introduction 📖
This research investigates a novel antifouling membrane based on a Polymerisable Bicontinuous Microemulsion (PBM) technique for Membrane Bioreactor (MBR) treatment of textile wastewater. The study compares the performance of the PBM membrane to a commercial uncoated UF membrane.
Objective 🎯
The objective of the study is to:
Develop and test a novel antifouling PBM membrane for MBR treatment of textile wastewater.
Compare the performance of the PBM membrane to a commercial uncoated UF membrane.
Evaluate the antifouling and antimicrobial properties of the PBM membrane.
Methodology 🔬
The PBM membrane was prepared using a PBM technique and formulated into an MBR module.
The MBR module was tested in a lab-scale MBR setup using model textile dye wastewater.
The performance of the PBM MBR module was compared to a commercial MBR module in terms of water permeability, COD removal efficiency, textile dye removal efficiency, fouling rate, and antimicrobial properties.
The PBM membrane was analyzed using AFM and SEM techniques to confirm the presence and stability of the coating.
Key Findings 🎉
The PBM MBR module significantly reduced fouling compared to the commercial MBR module. 🎉
The PBM MBR module showed higher blue dye removal efficiency and similar COD removal efficiency compared to the commercial module. 🎉
The PBM membrane exhibited antimicrobial properties and prevented biofouling. 🦠🚫
The PBM coating remained stable even after 105 days of operation. 💪
Implications 💡
The PBM membrane has the potential to reduce fouling and improve the performance of MBRs for textile wastewater treatment.
The antimicrobial properties of the PBM membrane can prevent biofouling and reduce the need for membrane cleaning. 🧼🚫
The PBM technique offers a low-cost and efficient method for preparing antifouling membranes. 💰
Recommendation for Future Research 🔍
The long-term performance of the PBM membrane in real textile wastewater treatment needs to be evaluated.
The potential of the PBM technique for preparing antifouling membranes for other applications should be explored.
Conclusion and Keynote Summary 🏆
The study demonstrates the potential of the PBM membrane as a novel antifouling membrane for MBR treatment of textile wastewater. The PBM membrane significantly reduced fouling, exhibited antimicrobial properties, and showed good performance in terms of dye and COD removal. Further research is needed to optimize the membrane preparation process and evaluate its long-term performance in real wastewater treatment applications.
