膜系统通常用于水工业中以生产饮用水和用于高级废水处理。膜系统的主要缺点之一是生物膜形成（生物结垢），其导致膜性能的不可接受的下降。三种新的原位生物污垢表征技术进行了评估：（i）光学相干断层扫描（OCT），（ii）平面光电二极管，和（iii）核磁共振（NMR）。前两种技术进行了评估，使用纳米过滤（NF）膜的表面上生长的生物膜，使用透明的膜污染模拟器，准确地模拟螺旋缠绕模块，修改为原位生物膜成像。对于NMR研究，使用螺旋缠绕的反渗透膜组件。结果表明，这些技术可以提供信息，以准确地重建生物膜，无论是与2-D（OCT，平面optodes和NMR），或3-D（OCT和NMR）扫描。这些非破坏性的工具可以阐明流体动力学的相互作用。
AbstractMembrane systems are commonly used in the water industry to produce potable water and for advanced wastewater treatment. One of the major drawbacks of membrane systems is biofilm formation (biofouling), which results in an unacceptable decline in membrane performance. Three novel in situ biofouling characterization techniques were assessed: (i) optical coherence tomography (OCT), (ii) planar optodes, and (iii) nuclear magnetic resonance (NMR). The first two techniques were assessed using a biofilm grown on the surface of nanofiltration (NF) membranes using a transparent membrane fouling simulator that accurately simulates spiral wound modules, modified for in situ biofilm imaging. For the NMR study, a spiral wound reverse osmosis membrane module was used. Results show that these techniques can provide information to reconstruct the biofilm accurately, either with 2-D (OCT, planar optodes and NMR), or 3-D (OCT and NMR) scans. These non-destructive tools can elucidate the interaction of hydrodynamic...
