BW-8040XLFR Fouling Resistant RO Membrane Element
The BW-8040XLFR FR Series fouling resistant reverse osmosis membrane element is designed for challenging feed water conditions, reclaimed water, wastewater reuse, and high-fouling industrial RO applications. Its advanced anti-fouling surface, 34-mil wide feed spacer, and optimized surface charge reduce organic and microbial adhesion, improve cleaning efficiency, and extend membrane life.
FR Series membranes are aromatic polyamide thin-film composite membranes engineered for complex influent water with high fouling potential. They provide high salt rejection, low pressure drop, and excellent recovery after cleaning, ensuring stable and efficient RO performance.
