Investigation of GO-MNP-HAP hollow fibre and disc membrane for oily wastewater treatment: article

The membrane separation technology has been seen as an alternative wastewater treatment toward the conventional treatment. However, the membrane separation also has several disadvantages such as fouling and generally low selectivity. Thus, a new material which is graphene oxide magneticnanoparticles hydroxyapatite (GO-MNP-HAP) was introduced. GO-MNP-HAP was synthesized through the modified Hummer’s method and chemical in situ method. The GO-MNP-Hap was coated on to the surface of ceramic supported hollow fibre and disc membrane to reduce the fouling effet of the membrane. The characterization of the GOMNP-HAP hollow fibre and disc membrane was investigated by using, X-ray diffraction (XRD), and Fourier Transform infrared (FTIR) The performance study of the GO-MNP-HAP ceramic supported membrane was evaluated through oily wastewater rejection at different concentration. The GO-MNPHAP coated membrane display higher permeate flux varied from 1201.58 L/m2.h to 16689.10 L/m2.h and oil rejection rate up to 98% compared to the bare membrane.
