摘要
膜污垢的挑战一直阻碍着膜技术的进步。图案化膜表面的构建有望显著减轻膜污垢的影响。在这项研究中,通过三维打印结合浸涂工艺,制造出了具有波纹图案的陶瓷微滤膜。为了评估表面图案对陶瓷膜性能的影响,我们首先比较了直管膜和波纹管膜的孔径和纯水通量。两种配置都表现出相似的参数:支撑孔径约为 1 μm,膜层孔径约为 110 nm,纯水渗透率约为 950 L m-2 h-1 -bar-1。在过滤纳米颗粒悬浮液、水包油乳剂和细菌悬浮液时,波纹陶瓷膜的防污性能优于直膜。具体来说,在纳米颗粒悬浮液浓度为 2000 ppm、跨膜压力为 0.2 MPa、流速为 1.0 m s-1 的条件下,波纹膜的稳定通量约为直膜的 1.7 倍。此外,我们还通过数值模拟探索了表面图案化对流体动力学的影响。图案化膜管中湍流耗散率的提高表明表面湍流增加,去除污染物的能力提高。这项研究为开发具有更强防污能力的陶瓷膜用于水处理提供了新的见解。
Construction of anti-fouling ceramic tubular membranes with corrugated inner surfaces using DLP 3D printing
The challenge of membrane fouling persistently hinders the advancement of membrane technology. The construction of patterned membrane surfaces is anticipated to mitigate the effects of membrane fouling significantly. In this study, ceramic microfiltration membranes with corrugated patterns were fabricated by 3D printing combined with the dip-coating process. To assess the impact of surface patterning on ceramic membrane performance, we initially compared the pore size and pure water flux between straight and corrugated membrane tubes. Both configurations exhibited similar parameters: a support pore size of approximately 1 μm, a membrane layer pore size of about 110 nm, and a pure water permeance of around 950 L m−2 h−1·bar−1. The corrugated ceramic membranes demonstrated superior anti-fouling properties compared to their straight counterparts during the filtration of nanoparticle suspensions, oil-in-water emulsions, and bacterial suspensions. Specifically, under a nanoparticle suspension concentration of 2000 ppm, a transmembrane pressure of 0.2 MPa, and a flow rate of 1.0 m s−1, the corrugated membrane achieved a stable flux of approximately 1.7 times greater than that of the straight membrane. Furthermore, we explored the effects of surface patterning on fluid dynamics through numerical simulations. The enhanced turbulence dissipation rate in the patterned membrane tubes suggests increased surface turbulence and an improved capacity to remove contaminants. This research offers novel insights into the development of ceramic membranes with enhanced anti-fouling capabilities for water treatment.
