Posttreatment of Reverse Osmosis Product Waters
Reverse osmosis (RO) product water usually requires posttreatment, regardless of the type of RO device, the chemical nature of the RO membrane, and the intended application of the water. Posttreatment requirements depend primarily on the application and must be determined on a case‐by‐case basis. For many industrial applications, posttreatment consists of demineralization by means of ion exchange and disinfection with ultraviolet radiation. Posttreatments for municipal applications include pH adjustment with bases or a degasifier (or both), reduction of corrosiveness, and disinfection with chlorine. Details of these posttreatments are given for RO product waters from brackish as well as seawater sources. The economics of these treatment processes are also presented.
