RO和NF膜工艺的渗透后处理通常相当广泛，在很大程度上取决于原水供应的类型和质量。本文涉及的主要后处理装置操作包括碱度回收、气提、消毒和稳定或腐蚀控制。此外，还举例说明了海水、微咸水、佛罗里达州沿海含水层和佛罗里达州沿海表层地下水在后处理过程中预期的典型水质变化。

Permeate post-treatment for RO and NF membrane processes in general can be fairly extensive and depends to a large extent upon the type and quality of the raw water supply. The primary post-treatment unit operations covered in this paper are alkalinity recovery, gas stripping, disinfection, and stabilization or corrosion control. In addition, examples of typical water quality changes expected in post-treatment are illustrated for a sea water, brackish water, a coastal Florida aquifer, and coastal surficial Florida groundwater.
