本研究的目的是:通过进行纳滤（NF）的中试规模测试，满足信息收集规则（ICR）的要求；确定NF用于处理卡诺布鲁克站（CBS）的水源水时，是否能提供符合第二阶段消毒剂/消毒副产品法规的成品水；并评估CBS使用双膜系统的运营问题和成本影响。这项试点研究是在1997年11月至1998年4月期间进行的，目标是实现至少3300个工作小时。在研究之前，对四种NF膜进行了实验室规模的筛选。采用单元素台架试验装置，在系统回收率约为66%的情况下进行精矿回收，以模拟单通道、多阵列系统在溶液回收率为93%的情况下运行- 扩散溶质通道模型。筛选的目的是确定一种具有高比通量、高TOC/UVA-254截留率和低钙/碱度截留率的最佳组合的膜，以便最大限度地去除DBP前体，最小化对成品水稳定性的影响，并最小化能源使用。基于这些标准，以及需要获得快速交付时间以满足ICR计划的要求，在中试研究中选择了Osmonics DESAL型号HL4040FF膜元件。包括5个参考文献、表格、图表。

The objectives of this study were to: meet Information Collection Rule (ICR) requirements by conducting pilot-scale testing of nanofiltration (NF); determine if NF, when used to treat source water at the Canoe Brook Station (CBS),would provide a finished water meeting Stage II Disinfectant/Disinfection Byproducts regulations; and assess the operational issues and cost implications of using a dual membrane system at CBS. The pilot study was conducted during the period of November 1997 through April 1998 with a goal of achieving a minimum of 3,300 operational hours. In advance of the study, a bench-scale screening of four NF membranes was performed. A single element bench test apparatus was employed with concentrate recycle at ~66% system recovery to simulate a single pass, multiple array system operated at 93 percent recovery based on a solution-diffusion solute passage model. Screening was designed to identify a membrane having the best combination of high specific flux, high TOC/UVA-254 rejection and low calcium/alkalinity rejection in order to maximize DBP precursor removal, minimize impacts on finished water stability and minimize energy use. Based on these criteria, along with the need to obtain quick delivery times to meet the ICR schedule, the Osmonics DESAL model HL4040FF membrane element was selected for use in the pilot study.
