Enhancing Membrane Performance for Pharmaceutical Contaminant Removal: A Statistical Study

Introduction:
Pharmaceutical contaminants in water pose serious environmental and health concerns. Recent research evaluates the effectiveness of ultrafiltration membranes in removing pharmaceutical compounds. This study, conducted by researchers from the Polytechnic University of Valencia, analyzes the influence of membrane cut-off size, pH levels, and feed concentration on filtration efficiency.

Key Findings on Membrane Performance

• Membrane Technology & Efficiency: Ultrafiltration membranes effectively remove ibuprofen, naproxen, diclofenac, and trimethoprim, with pH playing a crucial role in rejection rates.
• Statistical Analysis Using ANOVA: The study used ANOVA to determine significant factors affecting membrane flux and rejection rates. High pH values correlated with increased rejection of hydrophobic compounds.
• Impact of pH: The rejection efficiency was significantly affected by the pH level of the feed water. For ibuprofen, naproxen, and diclofenac, higher pH levels resulted in better rejection rates.
• Membrane Cut-off Size Matters: The best rejection results were observed with a 1 kDa membrane, particularly for hydrophobic compounds. However, caffeine exhibited lower rejection across all membranes, indicating a need for further study.

Integration of External Medical Sources:
The World Health Organization (WHO) emphasizes the growing concern of pharmaceutical pollutants in water sources, advocating for improved filtration technologies to mitigate risks to public health.
