Impact of industrial effluents on the environment and human health and their remediation using MOFs-based hybrid membrane filtration techniques


The hazardous risk posed by industrial effluent discharge into the ecosystem has raised a plethora of environmental issues, public health, and safety concerns. The effluents from industries such as tanning, leather, petrochemicals, pharmaceuticals, and textiles put significant stress on the aquatic ecosystem, which induces significant toxicity, participates in endocrine disruptions, and inhibits reproductive functions. Therefore, this review paper presented an overall abridgment of the effects of these effluents and their ability to synergize with modern pollutants such as pharmaceuticals, cosmetic chemicals, nanoparticles, and heavy metals. We further emphasize the metal organic framework (MOF) based membrane filtration approach for remediation of industrial effluents in comparison to the traditional remediation process. The MOF based-hybrid membrane filters provide higher reusability, better adsorption, a larger surface area, and superior removal rates through the implication of nanotechnology, while the traditional remediation process offers poorer filtration rates and stability. For example, MIL-100 (Fe)-UF and MIL-101(Cr)-UF exhibited high removal rates (94.7%) of natural organic matter NOM. It also elucidated the backstage processes involved in the remediation mechanism of MOFs based-hybrid membrane filtration of the discussed effluents.
