Surface Microstructure Drives Biofilm Formation and Biofouling of Graphene Oxide Membranes in Practical Water Treatment

“…These results indicated that the Fe­(OH) 3 /GO membrane had a better long-term antibiofouling performance. In addition, the biofilm resistance of the Fe­(OH) 3 /GO membrane increased more slowly than the other two membranes at the early stage, which demonstrated that the Fe­(OH) 3 /GO membrane was also able to delay the rate of fouling, and this can be attributed to the favorable hydrophilicity and lower ζ potential that acted against the adhesion of foulants on the membrane surface …”

Flexible and Mechanically Robust Nanofiber Membrane with Candle Soot-Induced Rough Surface for Organic Liquid Separation

“…Similar characteristics also appeared in the dynamic contact angle of FUSFM-0 and FUSFM-0.15 in DMSO for PE droplets (Figure S15). , According to classical wetting theory, the hierarchical roughness structure is necessary for the material to obtain superwettability . Afterward, the dynamic wettability behavior of oil droplets on the FUSFM-0.15 surface was investigated by a high-speed camera (all detailed information is shown in Figure S16).…”

Construction of a Multiscaled Synergistic Membrane for Efficient Dye Adsorption and Emulsion Separation

“…The permeation flux of the membrane was calculated by measuring filtration time (T) under a fixed filtrate volume (V), as shown in eq 2. 45 The fouling resistance and stability of the membrane were assessed by quantifying and calculating the variation in pure water permeation flux before (Flux b ) and after emulsion separation (Flux a ), termed the flux recovery rate (FRR). The FRR was calculated using eq 3 46 A UV−vis spectrophotometer was used to determine the oil content of the emulsion.…”

“…Deionized water was used to stabilize the flow rate, and the pressure was set to 0.1 MPa, and then the deionized water was replaced by oil-in-water emulsion during filtration. The permeation flux of the membrane was calculated by measuring filtration time ( T ) under a fixed filtrate volume ( V ), as shown in eq . The fouling resistance and stability of the membrane were assessed by quantifying and calculating the variation in pure water permeation flux before (Flux b ) and after emulsion separation (Flux a ), termed the flux recovery rate (FRR).…”
