在本文中，开发了一种新的工具，只需要在操作时进行流量控制，以评估 在线检测给定水产生膜生物污染的能力；将其用作替代 尸检也进行了评估。纳滤膜样品被定植在从这些样品改编而来的培养装置中 用于研究饮用水网络中的生物膜（Servais等人，2004年）。这些孵化 设备为PVC圆柱形反应器，配有6个圆形支架；那些支持 暴露在表面的纳滤膜盘或“优惠券”上，表面覆盖网格间隔物， 这在螺旋缠绕组件污垢现象中非常重要。反应堆被送入了一个反应堆 待测水的连续流动（与纳滤模块的进水相同），因此 使膜试片在与膜相切的水流接触处定植 其表面以4厘米/秒的恒定速度移动。 在反应器中定植后，细菌生物量增加 根据固定或吸附在膜试片上的材料估算。本文介绍了采样策略、中试装置的后续工作、生物膜特性和测试条件。包括10个参考文献、表格和图表。

In this paper, a new tool requiring only flow control as operation was developed in order to assess on-line the ability of a given water to generate membrane biofouling; its use as an alternative to the autopsy was also evaluated. Nanofiltration membrane coupons were colonized in incubation devices adapted from those used to study biofilm in drinking water networks (Servais et al., 2004). These incubation devices are PVC cylinder-shape reactors that were fitted with 6 circular supports; those supports exposed at their surface the nanofiltration membrane disc or "coupon" covered with a grid-spacer, which is of importance in spiral wound module fouling phenomena. The reactor was fed a continuous flow of water to be tested (same waters as those feeding nanofiltration modules), thus allowing the membrane coupons to become colonized at the contact of the water flowing tangentially to its surface at a constant velocity of 4 cm/s. After colonization in the reactor, bacterial biomass was estimated on the material fixed or adsorbed on the membrane coupons. Sampling strategy, follow-up of the pilot units, biofilm characterization, and testing conditions are presented. Includes 10 references, tables, figures.
