Abstract ：
在本研究中,将不同孔径的超滤膜用于过滤活性污泥悬浮液,以探究不同孔径膜的超滤膜过滤性能.结果表明:渗透滤液的累积体积随孔径的增大而减小.过滤初期,膜的渗透通量随着孔径的增大而增大.过滤后期,膜的渗透通量随着孔径的增大而减小.膜孔径越大,有效膜面积下降得越快,达到稳定有效膜面积的时间越短.同时,通过计算孔堵塞阻力和膜的有效膜面积可以很好地评估超滤膜过滤性能,孔径小的膜孔内阻力占比小、受污染程度低和抗污性能好.

Abstract ：
This study describes the preparation of graphitic carbon nitride (g-C3N4), hematite (alpha-Fe2O3), and their g-C3N4/alpha-Fe2O3 heterostructure for the photocatalytic removal of methyl orange (MO) under visible light illumination. The facile hydrothermal approach was utilized for the preparation of the nanomaterials. Powder X-ray diffraction (XRD), Scanning electron microscopy (SEM), Energy dispersive X-ray (EDX), and Brunauer-Emmett-Teller (BET) were carried out to study the physiochemical and optoelectronic properties of all the synthesized photocatalysts. Based on the X-ray photoelectron spectroscopy (XPS) and UV-visible diffuse reflectance (DRS) results, an energy level diagram vs. SHE was established. The acquired results indicated that the nanocomposite exhibited a type-II heterojunction and degraded the MO dye by 97%. The degradation ability of the nanocomposite was higher than that of pristine g-C3N4 (41%) and alpha-Fe2O3 (30%) photocatalysts under 300 min of light irradiation. The formation of a type-II heterostructure with desirable band alignment and band edge positions for efficient interfacial charge carrier separation along with a larger specific surface area was collectively responsible for the higher photocatalytic efficiency of the g-C3N4/alpha-Fe2O3 nanocomposite. The mechanism of the nanocomposite was also studied through results obtained from UV-vis and XPS analyses. A reactive species trapping experiment confirmed the involvement of the superoxide radical anion (O-2(& BULL;-)) as the key reactive oxygen species for MO removal. The degradation kinetics were also monitored, and the reaction was observed to be pseudo-first order. Moreover, the sustainability of the photocatalyst was also investigated.

Abstract ：
Recently, rising distress over ecological pollution owing to water contamination by coloring effluents primarily due to dyes is of growing concern. The development of semiconductor/magnetic oxide-based nanomaterials has verified to be a potent remediation means for water pollution. In the present article, the fabrication of nanocomposites was carried out by the facile hydrothermal method. The ZnO and ZnSe nanoparticles were in situ formed on the α-Fe2O3 layer, thereby forming a heterojunction. The prepared α-Fe2O3/ZnSe nanocomposite possessed a degradation of 98.9% for a Congo red aqueous solution of 100 ppm. The α-Fe2O3/ZnO nanocomposite showed only 26% degradation of 100 ppm dye solution depicting a poor photocatalytic performance. This is attributed to the formation of recombination-enhanced configuration (type-I heterostructure) in the α-Fe2O3/ZnO nanocomposite (NC). In contrast, α-Fe2O3/ZnSe NC accomplished a higher and enhanced photocatalytic response. The key rationale for elevated photocatalytic response is the establishment of a recombination-free configuration (type-II heterostructure). Thus, α-Fe2O3/ZnSe NC known as one of outstanding nanoparticle-nanocomposite photocatalysts was synthesized under mild conditions exclusive of some multifaceted post-treatment, for dye abatement process.

Abstract ：
How to precisely describe the fouling behavior of activated sludge suspension in constant flux cross-flow filtration is a challenge. In this paper, a three-mechanism (standard pore blocking, complete pore blocking and cake filtration) model was established based on the classic blocking law to describe the fouling behavior of activated sludge suspension in the constant flux cross-flow filtration. The results showed that the predictions of the proposed model showed good agreements with experimental data not only for activated sludge suspension (R-2 >= 0.994), but also for bovine serum albumin protein (BSA) (R-2 >= 0.966), humic acid (HA) (R-2 >= 0.940), sodium alginate (SA) (R-2 >= 0.801) and kaolin (R-2 >= 0.961). Meanwhile, for activated sludge suspension, the variation rate of the cake resistance increased with the filtration flux, and the steady available membrane area ratio (A(steady)/A(0)) was independent on the filtration flux while it decreased with the increase of MLSS concentration. In addition, the available membrane area ratio (A(t)/A(0)) decreased slower for activated sludge suspension than that for single model solution (BSA, HA and SA) in the fouling process.

Abstract ：
In this study, error function was used to analyze the membrane fouling behavior (flux decay) for bovine serum album (BSA) solution in dead-end mode and for kaolin suspension in cross-flow mode under constant pressure. The results showed that the predictions of error function had good agreements with experimental data both in dead-end mode and cross-flow mode. Meanwhile, both higher concentration and higher TMP could accelerate the membrane fouling rate. In addition, the parameter k in error function decreased with the increase of concentration or TMP. Thus, smaller parameter k represented more serious membrane fouling. © Content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence.

Abstract ：
Extracellular polymeric substances (EPSs) in activated sludge suspensions are the key substances leading to the membrane fouling. In order to understand the effect of EPSs on the membrane fouling, the actual EPSs solution extracted from activated sludge suspensions was used as the feed solution to conduct dead-end microfiltration experiment under different pressures by using different membranes. The flux (J), fouling resistances (Rm, Rp, Rc and Rtotal) and the available membrane area (A/A0) were used to describe the membrane fouling. The results showed that with the increase of pressure, J and Rtotal increased. Rp firstly increased and then kept constant, Rc always increased and became the dominant resistance. A/A0 decreased from 1 to a constant. Rc plays a key role on Rtotal for different membranes under the same pressure. The sequence of the steady available membrane area (Asteady/A0) for different pressures was: 63.0% (0.05MPa)> 56.5% (0.08MPa)> 53.6% (0.10MPa), and that for different membranes was: 80.1% (0.2μm PES) > 79.9% (0.1μm PES) > 78.4% (0.1μm PAN) > 53.6% (0.1μm PVDF). © Content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence.

Abstract ：
In order to sufficiently study the effects of stirring speed and temperature on the membrane flux, the flux recovery rate (FRR) and model parameters (k1, k2, k3 and Ri) of the PAN membrane (200kDa) fouled by yeast suspension, a series of rinsing experiments were carried out. Meanwhile, the instantaneous membrane flux was predicted by the rinsing model and corresponding regression equation of model parameters was obtained. The result indicated that the model shows a good agreement (R2>0.9700) and the temperature has a more significant effect on FRR and model parameters (k1, k2, k3 and Ri). FRR increased from 58.40% to 99.41% when the temperature increase from 25°C to 55°C (the rate constant of dissolution increased from 0.00371 m-1 to 0.00531 m-1) while it only increased from 55.67% to 67.50% when the stirring speed increases from 200 rpm to 800 rpm (the rate constant of dissolution increased from 0.00366 m-1 to 0.00456 m-1). In addition, the rinsing condition can be optimized by the combination of the prediction model of flux (equation (1)) and the regression equation (equation (2)) to obtain the optimal cleaning condition. © Content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence.

Abstract ：
This study systematically investigated the fouling behavior and mechanism of PAN Microfiltration (MF) membrane fouled with the model binary mixture (bovine serum albumin (BSA) and sodium alginate (SA)) of extracellular polymer substance (EPS) solution under different concentration and transmembrane pressure (TMP). The result showed that the fouling mechanism of the model binary mixture was the pore blocking and cake formation. Moreover, the SA plays a dominant role in the model binary mixture (BSA/SA). The higher SA concentration could cause the more serious membrane fouling (both the flux (J) and the available membrane area (A/A0) decreased), and the total resistance increased and caused the fouling mechanism changing from combined complete blocking and cake filtration into individual cake filtration appeared earlier. In addition, increasing of the TMP can also aggravate membrane fouling and it could be accurately described by the cake-complete model. This studied offered insight into the model binary mixture in the fouling behavior and mechanism, which can be used as guidance for practical application. © Content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence.

Abstract ：
A new model based on the removal mechanism of loose/compact cake and the re-deposition mechanism of foulants was proposed to predict the instantaneous fouling resistance (Rf(t)) in the rinsing process of 0.1 mu m PAN membrane fouled with activated sludge. The variation trend of Rf(t) was also analyzed by the removal rate of loose/compact cake (rr-ose/rr-compact) and the re-deposition rate of foulants (rre-deposition). Moreover, the model was validated by using other foulants (yeast, actual activated sludge, HA and SA) and membranes (0.1 mu m PES and PVDF membranes). The results showed that the model predictions had good agreements with experimental data at different cross-flow velocities (1.0, 1.5, 2.0 and 2.5 m/s) or temperatures (25, 30, 35 and 40 degrees C) (R2 0.9900). Besides, the variation trend of Rf(t) could be divided into three stages: (i) Rf(t) quickly decreased and the removal of loose cake was almost completed at rinsing time of t1 (first transition point) (rrose = 0); (ii) Rf(t) slowly decreased and Rf(t) reached to minimum (rr-compact = rre-deposition) at t2 (second transition point); (iii) Rf(t) slightly increased after t2 (rr-compact(t)<rre-deposition(t)). This model would provide an accurate method to analyze the variation trend of Rf(t) in the rinsing process and a theoretical basis for the optimization of rinsing conditions.
