WebJun 25, 2024 · Membranes which were hydrophobic and positively charged have higher permeate flux and lower fouling resistance. Polyphenols were adsorbed by membranes as irreversible fouling and also had an important contribution in cake layer fouling. Retention of polyphenols on polyethersulfon 5-kDa membrane was the largest, while that on PVDF … Websubjected to fouling. The convergence between the fouling resistance used in the design and the final fouling resistance in the simulation is promoted by an external loop. Among the different fouling problems, this paper presents the proposed procedure applied to chemical reaction fouling in crude oil streams. The article is organized as follows.
WebApr 19, 2024 · Importantly, the membranes showed ultralow protein adsorption and exceptional fouling resistance, outperforming other membranes. This work demonstrates the high efficiency of PTMAO zwitterionization in mitigating membrane fouling and provides a new approach to prepare fouling-resistant membranes. Supporting Information WebAug 3, 2024 · To determine the fouling resistance properties, the membranes were washed with milli-Q water after the 72 h of fouling experiments, and the pure water fluxes (J w 2) were re-determined. The different fouling ratios were were then quantified using Equations (6)–(9).
WebFouling resistance (R c) can be obtained from flux and TMP data by applying Darcy's Eq. (2).
