快速实验室规模膜试验（RBSMT）的中心是一个带循环的切向流平板单元，它代表了处理全尺寸系统平均进料的全尺寸螺旋缠绕纳滤元件的微分元件。RBSMT包含了操作参数，如恢复、压力、横流速度和近似现场规模操作的水力条件。使用RBSMT对四个常规处理的地表水和一个未处理的地下水进行了评估。经过纳滤后，所有测试的水将满足消毒剂/消毒副产品规则的第一阶段要求，四个地表水将满足第二阶段要求。包括22个参考文献、表格和图表。

At the center of the rapid bench-scale membrane test (RBSMT) is a tangential-flow flat-sheet cell with recycle, which represents a differential element of a full-scale spiral-wound nanofiltration element treating the average feed for a full-scale system. The RBSMT incorporates operational parameters, such as recovery, pressure, crossflow velocity, and hydraulic conditions that approximate field-scale operation. Four conventionally treated surface waters and one untreated groundwater were evaluated using the RBSMT. All of the waters tested would meet the Stage 1 requirements of the Disinfectants/Disinfection Byproduct Rule after nanofiltration, and the four surface waters would satisfy the Stage 2 requirements.
