1 Scope
This document specifies design, materials selection, construction and operation of Purified Water (PW) and Water for Injection (WFI) pretreatment and membrane-based production systems.
As many different types of feed water are possible, different components and configurations are presented. A decision matrix is provided to give guidance for the different types of feed water.
This document excludes
-
— selection of the appropriate compendial water definition per system: e.g. PW, WFI or other;
-
— thermal process for generation of PW/WFI;
-
— loops, storage and distribution;
-
— pure steam generation and distribution;
-
— laboratory water systems and
-
— validation.
