各种处理专用膜类型的发展提高了膜的可行性，以满足当今的饮用水问题。膜系统提供的高处理度要求对膜产品水进行额外处理或后处理（例如脱气、化学添加和/或与其他成品水混合）。根据精矿处理方法的不同，可能需要进行某种形式的精矿后处理。协助选择合适的膜柱- 处理，了解膜系统，包括预处理和膜类型，以及成品水目标。后处理方法应包括选择和验证适当的腐蚀监测技术。本文讨论了用于腐蚀控制、消毒、脱气和挥发性有机化学品控制的后处理。三个案例研究说明了微咸水、高颜色中等硬度地下水和海水的后处理选项。

The development of various treatment-specific membrane types has increased the viability of membranes to meet today's drinking water problems. The high degree of treatment provided by membrane systems necessitates the need for additional treatment or post-treatment (e.g., degasification, chemical addition, and/or blending with other finished water supplies) of membrane product water. Depending on the method of concentrate disposal, some form of concentrate post-treatment may be necessary. To assist in selecting the appropriate membrane post- treatment, an understanding of the membrane system, including pretreatment and membrane type, and finished water goals must be understood. The post-treatment methodology should include selecting and verifying an appropriate corrosion monitoring technique. This paper discusses post-treatment for corrosion control, disinfection, degasification, and control of volatile organic chemicals. Three case studies illustrate post-treatment options for brackish water, highly colored moderately hard groundwater, and seawater.
