Characterization of particle deposition during crossflow filtration as influenced by permeate flux andcrossflow velocity using a microfluidic filtration system

Hongzhan Di, Gregory J. O. Martin, Dave E. Dunstan

《化学科学与工程前沿(英文)》 2021年 第15卷 第3期   页码 552-561 doi: 10.1007/s11705-020-1962-5

摘要: Particle deposition during crossflow filtration is significantly influenced by the operating conditions, in particular the permeate flux and crossflow velocity. However, there is a lack of detailed knowledge about how deposit layer structures and distributions depend on operating parameters. This study uses a microfluidic visualisation filtration system to examine the influence of operating conditions on the deposition process during crossflow ultrafiltration from a microscopic perspective. Increasing the permeate flux caused an increasing amount of deposition and a thicker deposit layer. Higher crossflow velocities reduced the extent of deposition. The degree of deposition varied over a range of operating conditions due to the altered hydrodynamic forces exerted on the particles, which can be examined by the deposition probability according to an existing model. Building on this, an empirical correlation between the deposition probability and volume of deposition as function of filtration time was developed, which gave good agreement with experimental results. The effect of solution conditions was also involved in this correlation as a interaction energies. This could be useful for predicting the dynamic deposition process during crossflow filtration over a range of operating and solution conditions.

Membrane fouling control by ultrasound in an anaerobic membrane bioreactor

SUI Pengzhe, WEN Xianghua, HUANG Xia

《环境科学与工程前沿(英文)》 2007年 第1卷 第3期   页码 362-367 doi: 10.1007/s11783-007-0062-9

摘要: In this study, ultrasound was used to control the membrane fouling online in an anaerobic membrane bioreactor (AMBR). Short-term running experiments were carried out under different operating conditions to explore feasible ultrasonic parameters. The experimental results indicated that when the crossflow velocity was more than 1.0 m/s, membrane fouling could be controlled effectively only by hydrodynamic methods without ultrasound. When ultrasound was applied, an ultrasonic power range of 60–150 W was suitable for the membrane fouling control in the experimental system. The experimental results showed that the membrane fouling was controlled so well that membrane filtration resistance (Σ) could stay at 5 × 10 m for more than a week with the crossflow velocity of 0.75 m/s, which equaled the effect of crossflow velocity of more than 1.0 m/s without ultrasound.

摘要: Few long-term follow-up studies have compared the changes in renal function according to the type of statin used in Korea. We compared the long-term effects of statin intensity and type on the changes in the glomerular filtration rate (GFR). We extracted data of patients who took statin for the first time. We analyzed whether or not different statins affect the changes in GFR at 3 months after baseline and 4 years after. We included 3678 patients and analyzed the changes in GFR. The GFR decreased by 3.2%±0.4% on average 4 years after the first statin prescription, indicating statistically significant deterioration (from 83.5±0.4 mL/min/1.73 m to 79.9±0.4 mL/min/1.73 m , <0.001). When comparing the GFR among different statins, significant differences were observed between atorvastatin and fluvastatin (−5.3%±0.7% vs. 1.2%±2.2%, <0.05) and between atorvastatin and simvastatin (−5.3%±0.7% vs. −0.7%±0.8%, <0.05). In pitavastatin (odds ratio [OR]=0.64, 95% confidence interval [CI]=0.46–0.87, <0.005) and simvastatin (OR=0.69, 95% CI=0.53–0.91, <0.008), the GFR rate that decreased by<60 mL/min/1.73 m was significantly lower than that of atorvastatin. Regarding long-term statin intake, GFR changed with the type of statin. This work is the first in Korea to compare each statin in terms of changes in the GFR after the statin prescription.

摘要: A novel method was applied to co-recover proteins and humic acid from the dewatered sewage sludge for liquid fertilizer and animal feed. The proteins in sewage sludge were first extracted using the processes of ultra-sonication and acid precipitation, and then the humic acid was recovered via membrane filtration. The extraction efficiency was 125.9 mg humic acid?g VSS volatile suspended solids (VSS) and 123.9 mg proteins?g VSS at the optimal ultrasonic density of 1.5 W?mL . FT-IR spectrum results indicated that the recovered proteins and humic acid showed similar chemical characteristic to the natural proteins and humic acid. The acidic solution (pH 2) could be recycled and used more than 10 times during the co-recovery processes. In addition, the dewatered sludge could be easily biodegraded when the humic acid and proteins are extracted, which was essential for further utilization. These findings are of great significance for recovering valuable nutrient from sewage sludge.

摘要: Fe-Mn binary oxide incorporated into porous diatomite (FMBO-diatomite) was prepared in situ and regenerated in a fixed-bed column for arsenite [As(III)] and arsenate [As(V)] removal. Four consecutive adsorption cycles were operated under the following conditions: Initial arsenic concentration of 0.1 mg·L , empty bed contact time of 5 min, and pH 7.0. About 3000, 3300, 3800, and 4500 bed volumes of eligible effluent (arsenic concentration≤0.01 mg·L ) were obtained in four As(III) adsorption cycles; while about 2000, 2300, 2500, and 3100 bed volumes of eligible effluent were obtained in four As(V) adsorption cycles. The dissection results of FMBO-diatomite fixed-bed exhibited that small amounts of manganese and iron were transferred from the top of the fixed-bed to the bottom of the fixed-bed during As(III) removal process. Compared to the extremely low concentration of iron (<0.01 mg·L ), the fluctuation concentration of Mn in effluent of the As(III) removal column was in a range of 0.01–0.08 mg·L . The release of manganese suggested that manganese oxides played an important role in As(III) oxidation. Determined with the US EPA toxicity characteristic leaching procedure (TCLP), the leaching risk of As(III) on exhausted FMBO-diatomite was lower than that of As(V).

摘要: A hybrid membrane process for simultaneous sludge thickening and digestion (MSTD) was studied. During one cycle (15 d) of operation under a hydraulic retention time of 1 d, the concentration of mixed liquor suspended solids (MLSS) continuously increased from about 4 g·L to 34 g·L, and the mixed liquor volatile suspended solids (MLVSS) increased from about 3 g·L to over 22 g·L. About 42% of the MLVSS and 39% of the MLSS reduction were achieved. The thickening and digestion effects in the MSTD were further analyzed based on a mass balance analysis. Test results showed that biopolymers and cations of biomass were gradually released to the bulk solution during the process. It was also found that the capillary suction time, colloidal chemical oxygen demand, soluble microbial products, viscosity, and MLSS had significant positive correlations with the membrane fouling rate, whereas extracellular polymeric substances, polysaccharides, and proteins extracted from biomass had negative impacts on membrane fouling.
