“…The specific cake resistances (Eq. 2) calculated for the first cycle with the pristine membrane was equal to 44.5 × 10 15 m -1 kg -1 which is a classical values observed for organic matter surrogates fouling layer [40,41]. Interestingly, whatever the investigated irradiation dose the specific cake resistance was strongly reduced for the same filtered Table 2, the highest initial flux was obtained for the Cyst-10kGy membrane while the lowest flux, equals to 58 L/h/m 2 , was observed for both Cyst-100kGy and Phos-100kGy membranes.…”

Electron beam irradiation of polyvinylidene fluoride/polyvinylpyrrolidone ultrafiltration membrane in presence of zwitterions molecules evaluation of filtration performances. Radiation Physics and Chemistry, Elsevier, 2019, 159, pp. Abstract:In this research, the commercial PVDF/PVP membrane was irradiated at 10 and 100 kGy with electron beam (EB) to improve its fouling resistance capacity. Membrane irradiation was conducted in the presence of zwitterionic molecules (L-Cysteine, Phosphocholine) and with 2-(Dimethylamino)ethyl methacrylate). The main goal was to investigate the impact of irradiation in presence of zwitterions on the modification route of PVP within the polymer blend and to relate it to filtration performances. Globally, EB irradiation enhanced the membrane's filtration performance but this improvement cannot be sustained after several filtration cycles. Membranes irradiated with the lower absorbed dose (10 kGy) displayed higher permeate flux and lower cake resistance than membranes irradiated with the 100 kGy dose. The best sustainable anti-fouling capacity was observed for the membrane irradiated with 10 kGy in the presence of L-Cysteine. Membrane characterization showed that the membrane surface was modified by EB irradiation, with features such as smoother surface, modification of PVP and increased amount of crosslinking emphasizing the potential formation of PVP hydrogels. Despite obvious changes observed on membrane surface depending on the chosen compounds used for irradiation, membranes' analyses failed to identify sulphur, phosphorous grafted moieties. From this study, it is confirmed that membranes EB irradiation in presence of zwitterionic molecules is a promising technique to modify the PVDF/PVP blended polymer.

In this study, membrane fouling caused by paperboard mill treated effluent (PMTE) was investigated based on a dead-end ultrafiltration (UF) pilot-scale study. The membranes employed were commercial hydrophobic UF membranes made of polyethersulfone (PES) with a molecular weight cut-off of 10 kDa, 50 kDa, and 100 kDa. Membrane fouling mechanism during dead-end filtration, chemical analysis, field emission scanning electron microscopy (FESEM), energy-dispersive spectrophotometry (EDS), attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy and 3D fluorescence excitation–emission matrix (3DEEM) analysis were applied to understand which fraction of the dissolved and colloidal substances (DCS) caused the membrane fouling. The results indicated that the phenomenon controlling fouling mechanism tended to be cake layer formation (R2 ≥ 0.98) for all membranes tested. The 3DEEM results indicate that the majority of the organic foulants with fluorescence characteristics on the membrane were colloidal proteins (protein-like substances I+II) and macromolecular proteins (soluble microbial products, SMP-like substances). In addition, polysaccharide (cellulosic species), fatty and resin acid substances were identified on the fouled membrane by the ATR–FTIR analysis and play an important role in membrane fouling. In addition, the FESEM and EDS analyses indicate that the presence of inorganic foulants on the membrane surfaces, such as metal ions and especially Ca2+, can accelerate membrane fouling, whereas Mg and Si are linked to reversible fouling.

“…The membrane fouling mechanism is always an interesting aspect to researchers, and fouling models are useful tools for explaining such mechanisms. Most studies have utilized models to explain the different fouling mechanisms for different contaminants or properties, [31][32][33] while few studies have used models to explain the effects of operating parameters on membrane fouling.…”
