Summary: As an emerging MOF material, MIL-101(Cr) demonstrates a high NOM adsorption capacity and can improve permeate quality in both separation mode (SM) and coating mode (CM). MIL-101(Cr) influences membrane fouling behaviors and has a dual role in the integrated system, reducing fouling but also causing additional filtration resistance. The 7C-7C interactions and salt-bridges between MIL-101(Cr) and NOM play a dominant role in adsorption. SM is more efficient in mitigating membrane fouling, while CM achieves the same permeate quality with less MIL-101(Cr) usage and reaction time. This study provides a scientific basis for the widespread application of MOFs.
