本文介绍了一个利用超滤技术处理工业用水和生活用水的典型例子，即Bqua。该项目由欧盟委员会资助，展示了荷兰埃因霍温市膜技术的使用情况。除了这个具体的例子，还概述了荷兰使用微过滤和超滤技术进行地表水处理的研究活动。结合不同位置的膜性能结果，确定净膜通量对水质或预处理程度的依赖性。 定量给出了每种类型地表水的净通量范围，即未预处理、限制预处理或扩展预处理。净通量范围似乎或多或少与位置和膜类型无关。目前正在进行进一步的研究，以优化微过滤和超滤的成本模型，该模型对通量变化敏感，并包括预处理成本。包括4个参考文献、表格和图表。

A typical example of surface water treatment using ultrafiltration for industrial water and household water production, so called Bqua, is described in this article. This project is funded by the European Commission and shows the use of membrane technology in the city of Eindhoven, the Netherlands. Besides this specific example an overview of research activities for surface water treatment in the Netherlands using micro- and ultrafiltration is presented. Combining the results of membrane performances at various locations a dependency of net membrane flux on water quality or extent of pretreatment is determined. A range of net flux for each type of surface water, i.e. non-pretreated, restrictedly pretreated or extendedly pretreated, is given quantitatively. This net flux range appears to be more or less independent on location and membrane type. Further research is carried out at this moment to optimize a cost model of micro- and ultrafiltration that is sensitive for variations in flux and includes costs of pretreatment. Includes 4 references, tables, figures.
