Chemically Modified Nanofiltration Hollow Fiber Membranes for Heavy Metal Removal

National University of Singapore, Singapore, Singapore

TECHNOLOGY SUMMARY

This technology relates to a hollow fiber nanofiltration membrane (polymeric) that can remove both positively and negatively charged heavy metal ions from water. Rejection rates for cations can be 91-99% at 13 bar. For Cr2O72-, CdCl42- and HAsO42-, rejection is ~99.74%(pH 10), 99.88% and 99.82% at 15 bar.
