Hollow Fiber Nanofiltration

Our globally unique nanofiltration concept effectively removes impurities such as scale, heavy metals, organic matter, and microorganisms from water.

Hollow fibers can provide a larger specific surface area for filtration. Internal pressure allows for better control of the uniformity of the separation layer and membrane fouling. AQFILM uses modified PES as the support layer, which is formed in one step through a cross-linking reaction to generate a charged filtration skin layer on the surface. The hollow fiber nanofiltration membrane prepared by this method utilizes the mechanisms of "pore size sieving" and "mutual repulsion of like charges" to improve the rejection rate. Compared with the spiral-wound structure, the product features strong raw water adaptability, high pure water flux (60-80 LMH@3bar), high yield, and low energy consumption, and can effectively remove water quality impurities such as scale, heavy metals, organic matter, and microorganisms.
