Hypothesis
Can a gravity-driven membrane bioreactor effectively treat real fruit juice wastewater without requiring pre-treatment?
Conclusion
The gravity-driven membrane bioreactor effectively stabilized flux and achieved high removal rates for various contaminants in fruit juice wastewater.
Supporting Evidence
- The GDMBR achieved average removal rates of 82.99% for COD, 87.56% for BOD, 82.47% for NH4+-N, and 80.68% for TN.
- The stabilized flux level of the GDMBR was consistently between 2.5 to 4 L m−2 h−1.
- Microbial community analysis showed significant differences between sludge and raw water, indicating effective biodegradation.
Takeaway
This study shows that a special filter can clean fruit juice wastewater using gravity, making it easier and cheaper to treat.
Methodology
The study used a gravity-driven membrane bioreactor to treat fruit juice wastewater, monitoring flux and contaminant removal over time.
Limitations
The study did not include pre-treatment processes, which may affect the generalizability of the results.
