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].
