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 ：
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.

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 order to objectively elucidate the state of the membrane after long-term operation, the performance of a full-scale microfiltration-reverse osmosis (MF-RO) integrated membrane system with production capacity of 20,000 m3/d for wastewater reclamation was evaluated by collecting 10 years performance data. The foulants on 1 MF membrane and 12 RO membranes along the feed channel also were analyzed by membrane autopsy. The results indicate that the water quality of the system can still meet the customer requirements while the mechanical and desalting properties of the membranes were close to the abandoned standards. In terms of foulants distribution, the MF membrane surface was covered by a thick cake layer and the leading RO membrane suffered the highest fouling load. The predominate organic foulants on the membrane surface were protein and polysaccharide, and the main inorganic foulants were Fe and Ca, and their distribution showed two different trends along the feed channel. Regarding bio-foulants, the compositions of bacterial colonies on 12 RO membranes were basically the same, but the relative abundance of the dominant bacteria was different and the microbial diversity increased gradually from the leading element to the terminal one in both the two stages. © Content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence.

Abstract ：
In order to find a model solution to simulate actual extracellular polymeric substances (EPS) solution in terms of filterability behavior, a series of experiments were conducted in a dead-end unstirred cell with 0.1 μm polyvinylidene fluoride membranes using single/ binary mixtures consisting of sodium alginate (SA), bovine serum albumin (BSA) and humic acid (HA). It can obtain that the presence of BSA and SA is a necessary condition for model the filtration behavior of the actual EPS solution. Meanwhile, compared the actual EPS solution with binary mixtures model EPS solution can find that BSA/SA=140/58.3 and SA/HA=107/28.5 can exhibit the similar filtration behavior as actual EPS, while BSA/HA are far from that of actual EPS solution. The suitable type and combination of simulated solution were determined to improve the consistency with EPS solution in actual MBR system. © Content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence.

Abstract ：
Electroactive species modified electrodes are extensively studied as the mediator donor in homogeneous electrocatalytic reaction for electrochemical sensing purpose. In this paper, homogeneous electrocatalytic reaction within a thin layer modified electrode is investigated theoretically and experimentally to illustrate the electroactive species distribution on ferrocenedicarboxylic acid modified carbon black paste electrodes (FDACBPE). The voltammetric analysis of the fabricated FDACBPE reveals that the electrode is in diffusional control at the scan rate lower than 50 mV s-1 while a surface control electrode reaction is observed at a higher scan rate. Based on the experimental results, three finite element models including thin layer model, fixed mediator model and combined model are established to evaluate the homogeneous electrocatalytic reaction with FDACBPE. The numerical results show that the anodic peak gap order of 3 models is as follows: fixed mediator model > combined model > thin layer model. As validation of the proposed model, the comparison between experimental results and numerical data on both polished and unpolished FDACBPE indicates that the combined model data are more suitable for the description of experimental voltammograms compared with the other two models. Also, the comparison between these models suggests that both surface confined and diffusional FDA exist when FDACBPE is employed.

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.
