The influences of Keggin-type H3PW12O40 nanostructure on Polyurethane microfiltration membrane to reinforce screening organic pollutants from wastewater

Manifestly, unceasing growth industrialization has caused to produce the non-segregated phases, engendering complexity in wastewater remediation. Therefore, we endeavored to construct the electrospun Polyurethane (PU)-based Microfiltration (MF) membrane that the Keggin-type H3PW12O40 (KHPW) nanostructure embedded in it by simplified strategy; after that, the PU/KHPWx (x= 0.5, 1, 1.5, and 2 %wt) nanocomposite membranes executed to purify the emulsifier-stabilized Walnut oil (EWO). Fortunately, perfect wettability, controlled porosity, and high negative charge boosted the values of Permeated Water Flux (PWF) and Oil Rejection Efficiency (ORE), which equaled 2150 L.m−2.h−1 and 100 % for the 1400 mg.L-1 of EWO by the PU/KHPW2 membrane, respectively; after that, the fouling resistance parameter (i.e., the Flux Recovery Ratio (FRR)) improved to 62.18 % in pH = 9. Notably, the MB Removal Efficiency (MRE) surveyed to render the light-driven catalytic activities of KHPW, and the Taguchi method optimized the values of operational parameters. Hence, the MRE astonishingly elevated to 79.3 % by PU/KHPW2 at the ameliorated conditions under UV-light irradiation, conferring the self-cleaning merits to the PU/KHPWx samples. After reviewing previously published articles, these authentic observations about the multifunctional capabilities of PU/KHPW2 elucidated insights towards robust screening water pollutants, which discreetly could utilize it in the pre-treatment units of MF.
