Study on the fouling phenomena of poly(vinylidene fluoride) (PVDF) membrane by protein, yeast 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 three types of organic foulants, yeast, protein and sodium alginate with a concentration of 50mg/l, 40mg/l and 20 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 .

本子数据集为膜过滤过程中有机污染机理研究的成果。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三类有机污染物进行过滤：分别为酵母菌、蛋白质与海藻酸钠，其浓度依次为50mg/L、40mg/L与20mg/L。上述模式污染物在过滤前均经荧光染料染色处理。本数据集包含共聚焦激光扫描显微镜（confocal laser scanning microscope, CLSM）及其配套采集软件所捕获的PVDF膜表面污染层序列图像。本数据集可服务于膜有机污染机理相关研究人员，助力未来为水与污水处理行业开发新型膜材料及抗污染表面处理技术。
