The ISPE Good Practice Guide: Membrane-Based Water for Injection Systems provides expert guidance on the design, operation, maintenance, and quality aspects of membrane-based WFI systems, including generation, storage, and distribution. This Guide reflects an industry wide collaborative effort by a diverse range of industry experts that include equipment providers, engineering firms, consultants, and pharmaceutical manufacturers. The information presented in this guide is the combination of proven technological solutions, microbial control methods, process analytical technology, and operations and maintenance practices.

This Guide reviews the unit operations typically employed in continuous manufacturing and aims to establish a set of minimum equipment requirements for each system to function as part of an integrated process train. While most of the units are well-understood and used in batch manufacturing, the Guide considers the changes in physical and automation requirements that will allow each unit to work in concert as part of a successful continuous manufacturing platform. Operations unique to CM, loss-in-weight feeding and continuous blending, are discussed, including how these systems affect upstream and downstream operations.
