Paul Mueller Company Academy

Water for Injection (WFI) has traditionally been made for the pharmaceutical industry using distillation methods, boiling feedwater using plant steam, and condensing it using cooling water. While this tried-and-true method is still available using Paul Mueller Company’s Multiple Effect Stills and Single Effect Stills, changes in the European Pharmacopoeia have opened the door to other equivalent methods for WFI production.

Mueller Multiple Effect Stills and Pure Steam Generators come in a variety of sizes to ensure that one is available as close as possible to the size you need. However, often, the design capacity is not the maximum capacity of the unit. This means you may have “free” capacity available on your existing unit! Here are the steps to determining what “free” capacity you have available.
