Superfiltration (SF) membranes represent an exciting breakthrough in membrane technology, filling the gap between ultrafiltration (UF) and nanofiltration (NF). 

These innovative membranes showcase remarkable performance, exhibiting high NF-like organic rejection while maintaining low UF-like inorganic/salt rejection. What sets SF membranes apart is their exceptional hydrophilicity, making them incredibly water-loving. This unique feature, combined with a patented chemistry, delivers outstanding fouling resistance, even in applications once deemed unsuitable for membrane separation. 

With the utilization of the cutting-edge membrane filtration method, SF membranes redefine the possibilities in separation processes, providing sustainable solutions for various industries.
