Addressing emerging contaminant: The role of nano‐filtration in removing methylparaben from wastewater

Abstract Methylparaben, commonly found as an emerging contaminant in personal care products and pharmaceuticals, have raised concerns due to their potential endocrine‐disrupting effects on humans and male fish. Nano‐filtration presents a viable alternative for mitigating this contamination. In this paper, the first part explores advances in various methods, each of which facilitates the separation of paraben from aqueous media. In the later experimental segment, the flat sheet membrane module is used for nano‐filtration, for different operating parameters. The two NF300 & NF100 membranes are employed to see the efficiency of removal of nethylparaben from synthetic wastewater. The removal efficiency of methylparaben by NF300 membrane is 32.64%, while the removal efficiency by NF100 membrane is 70.46%. The efficiency of the membrane increases with the increase in pressure and decrease in the concentration. The outcome shows nano‐filtration is a promising technology for addressing the emerging contaminant methylparaben in waste water.
