USP Purified Water or WFI Storage and Distribution Systems


The USP Purified Water (WFI) Storage and Distribution System consists of a stainless steel vessel jacketed for heat transfer with the following associated equipment: a sterile vent filter, a sterile liquid filter, a UV sterilizer, a re-circulation loop, a re-circulation pump, a re-circulation water heater, and a control and instrumentation system for monitoring and adjustment of the system pressure, temperature, fluid level, and flow rates and for monitoring pH, TOC, O3 and conductivity. The system including the interior surface of the vessel, piping, valves, and any surface in potential contact with the product water is designed to be sanitized and/or sterilized with hot USP Purified Water or WFI.
