5. DuPont FilmTec™ BW30HRLE-440:
Anti-Fouling Design for Long-Term Stability
DuPont FilmTec™ BW30HRLE-440 incorporates
an optimized anti-fouling design to mitigate the impact of membrane fouling—a
key challenge in industrial water treatment [3]. Its advanced TFC polyamide
membrane surface and precision-engineered feed spacer reduce the accumulation
of organic and inorganic contaminants, minimizing pressure drop across the
vessel and extending the interval between cleaning cycles. The element’s wide
cleaning pH range (1–13) ensures effective removal of fouling deposits, further
extending membrane service life and reducing operational downtime. This
anti-fouling capability makes it ideal for treating feedwaters with moderate
fouling potential, such as industrial wastewater and groundwater [3].
