Ultrapure Pharmaceutical Water for Injection (WFI) Separate Bed Deionizer (DI) Guide

The calculations above can be used as a guide for ultrapure, hot sanitizable pharmaceutical twin bed demineralizer (DI) sizing. Stainless steel systems (316L, 316, 304) are the best options for applications that need to be sanitized with a heat process. Systems are also available in FRP and lined carbon steel. Ultrapure DI systems are ideal for any application with need for TDS (conductivity) reduction where the water isn’t ideal (e.g. low TDS or small particle TSS) for reverse osmosis systems. They are also ideal for oil and gas, petrochemical and chemical, power generation, food and beverage and critical boiler water pre-treatment and many other ultrapure water (UPW) applications.

When sizing pharmaceutical deionizer systems, many variables exist that are beyond the scope of the pharma water for injection (WFI) twin bed demineralizer calculator & guide below. Water chemistry, pressure and temperature are all variables that have effects on water DI sizing and are not considered. These guides are to be used for quick estimates for sizing, general design and footprints of ultrapure water two bed deionizer systems for Pharmaceutical applications.

Detailed pharmaceutical water for injection (WFI) deionizer sizing, including configurations (e.g. single, twin, triple or special multiple tank configurations), control types (Allen Bradley, GE, Siemens PLC, progressive flow, additive flow) or specific specifications like 316L, 304, or 316 stainless steel, Hastelloy or specific instrument and valve types, it is important that you call or email Nancrede Engineering at 888-56-WATER (569-2837).
