Study on the fouling phenomena of poly(vinylidene fluoride) (PVDF) membrane by protein and sodium alginate

This sub-collection is the result of an investigation into the mechanism of organic fouling in membrane filtration processes. In this experiment, poly(vinylidene fluoride) (PVDF) membranes were used to filter two types of organic foulants, protein and sodium alginate with a concentration of 50mg/l and 40 mg/l, respectively, from suspension in a dead-end filtration cell. These model foulants were stained with fluorescent dyes before filtration. This dataset contains a stack of images of the fouling layer on the PVDF membrane surface captured by a confocal laser scanning microscope (CLSM) and its associated acquisition software. This dataset would be useful to researchers who are investigating the membrane organic fouling mechanism so that new membrane materials and new anti-fouling surface treatment technologies can be developed for water and wastewater industry in the future.

本子数据集源于一项针对膜过滤过程中有机污染机理的研究。本实验采用聚偏氟乙烯（poly(vinylidene fluoride), PVDF）膜，在死端过滤池中对悬浮液中的两类膜污染物进行过滤：分别为浓度50mg/L的蛋白质与40mg/L的海藻酸钠。上述模式污染物在过滤前已通过荧光染料完成染色标记。本数据集包含由共聚焦激光扫描显微镜（confocal laser scanning microscope, CLSM）及其配套采集软件拍摄得到的PVDF膜表面污染层序列图像。本数据集可为膜有机污染机理相关研究人员提供数据支撑，助力未来为给排水及污水处理行业开发新型膜材料与抗污染表面处理技术。
