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.
