Strengths & Limitations
Strengths
- +Comprehensive review of experimental procedures.
- +Development of a predictive mathematical model.
- +Demonstration of complete contaminant removal in a long-term experiment.
Limitations
The effectiveness of biological filtration can be highly dependent on environmental conditions like temperature and pH, which might be difficult to control in a simple design project.
Reliability & validity
The reliability of the findings is supported by a long-term experimental demonstration of complete toxin removal. Validity is enhanced by the use of a predictive model that aligns with experimental observations, though its generalizability to all contaminant types and conditions would require further testing.

Paragraph starter
This design project draws inspiration from research demonstrating the efficacy of biofiltration systems in removing emerging contaminants. Specifically, the work by Undabeytia López et al. (2023) highlights how specialized bacteria and enzymes, utilized within filtration media, can actively degrade pollutants like cyanotoxins. Their findings suggest that the filter surface serves as a critical site for binding and subsequent catalytic breakdown, and that predictive modelling can optimize system design for contaminant concentration, flow rate, and filter dimensions. This principle of integrating active degradation into filtration is a key consideration for the proposed water purification system.
