Low Cost Ceramic Membrane Filtration for Application in Developing Countries: The Ceramic Silver-Impregnated Pot Filter 适用于发展中国家的低成本陶瓷膜过滤:陶瓷浸银罐式过滤器
发布日期: 2007-11-01
在世界各地的许多生产地点,一个低成本的陶瓷膜饮用水处理系统 这种过滤器被称为陶瓷浸银罐过滤器(CSF)。本研究的目的是收集 使用高科技方法从膜上获取性能数据和表征过滤材料 技术进行的研究表明,CSF能有效去除总大肠菌群和亚硫酸盐 减少梭菌孢子和大肠杆菌K12。结果表明,不需要应用 脑脊液中与梭菌孢子有关的银(隐孢子虫去除的替代物)。然而 含银的CSF系统对大肠杆菌K12的去除效果略好。MS2噬菌体仅为 部分从水中去除,对于不浸渍水的过滤器,效果显著更好 胶体银。经测量,过滤材料中的有效孔隙约为40µm,即 比大多数病原体都大。因此,过滤材料中的高扭曲度有助于提高效率 指示生物的物理清除。脑脊液的主要缺陷是水分不足 不足以为一个家庭提供饮用水的生产。包括9个参考文献、表格、图表。
At many production locations worldwide, a low-cost ceramic membrane drinking water treatment system is produced called the ceramic silver-impregnated pot filter (CSF). The objective of this study was to gather performance data and characterize the filter material using high-tech methods from membrane technology. The performed research indicated that CSF efficiently removes total coliforms, sulfite reducing Clostridium spores and E.coli K12. It was shown that there is no need for the application of silver in CSF concerning Clostridium spores (surrogate for Cryptosporidium removal). However, the removal of E.coli K12 was slightly better by the CSF system with silver. MS2 bacteriophages were only partially removed from the water, with significantly better results for filters without an impregnation of colloidal silver. The effective pores in the filter material were measured to be around 40 µm, which is larger than most pathogens. Hence, high tortuosities in the filter material contributed to the efficient physical removal of indicator organisms. The main deficiency of CSF proved to be the low water production which was insufficient to provide drinking water for a family. Includes 9 references, table, figures.
