本文简要概述了可用的纳滤（NF）/反渗透（RO）后处理选项，这些选项在适当的情况下 所采用的方法可以达到成品水质量，从而减轻环境中的许多潜在不利影响 分配系统。主题包括:混合多种水源；膜后处理考虑；配水系统中水质事件的相对风险 影响公用事业公司遵守法规；通过参数相关事件识别风险的概率和程度。包括4个参考文献、表格。

This paper provides a brief overview of available Nanofiltration (NF)/Reverse Osmosis (RO) post-treatment options, which when properly employed can achieve finished water quality that mitigates many potential adverse effects in the distribution system. Topics covered include: blending multiple source waters; membrane post treatment considerations; relative risk of water quality event(s) in a distribution system impacting a utility's compliance with regulations; and, probability and degree of risk identification by parameter-related events. Includes 4 references, tables.
