The Working Principle of WFI Storage and Distribution Loop
The WFI (Water for Injection) storage and distribution loop is a critical system in pharmaceutical manufacturing designed to continuously store and deliver high-purity water while preventing microbial growth.
The core principle involves constant circulation of WFI, typically held at a temperature above 70°C, throughout the entire facility. This high temperature effectively sanitizes the system and inhibits microbial growth. A circulation pump keeps the water flowing at a high velocity, creating a turbulent flow that prevents stagnant areas where bacteria could thrive.
The loop is constructed from high-quality 316L stainless steel with electropolished inner surfaces to minimize surface roughness and potential for biofilm formation. Key parameters like temperature, conductivity, and pressure are continuously monitored to ensure the water’s quality meets stringent pharmacopoeia standards before it is used in drug manufacturing processes.
