通常需要对反渗透（RO）产品水进行后处理，无论其预期用途、RO装置类型和RO膜的化学性质如何。后处理要求主要取决于应用，必须根据具体情况确定。本文讨论的最常用的后处理包括完全脱矿、pH值调整、减少腐蚀性的处理、紫外线辐射或氯化消毒，以及脱气以去除硫化氢。这些后处理的详细信息适用于微咸水和海水来源的反渗透产品水。还介绍了处理过程的成本。包括24个参考文献、表格和图表。

Posttreatment of reverse osmosis (RO) product water is usually required, regardless of the intended application, type of RO device, and the chemical nature of the RO membrane. Posttreatment requirements depend primarily on the application and must be determined on a case-by-case basis. The most frequently used posttreatments discussed in this article include complete demineralization, pH adjustment, treatment to reduce corrosiveness, disinfection with ultraviolet radiation or chlorination, and degasification to remove hydrogen sulfide. Details of these posttreatments are given for RO product waters from brackish as well as seawater sources. The costs of the treatment processes are also presented. Includes 24 references, tables, figures.
