BFMIN membrane cores consist of nanofiltration cores with 0.5–3 nm pore size and ultrafiltration cores with 5–50 nm pore size. Three core technologies including uniform fiber distribution, high-dimension lining and open-type assembly are adopted to maximize the functional performance of ultrafiltration and nanofiltration membranes.
