What is WFI (Water for Injection)?

Water for injection by definition is water that is intended for use in the manufacture of parenteral (i.e. injectable) drugs whose solvent is water. The USP (United States Pharmacopeia) defines this as highly purified waters containing less than 10 CFU/100 ml of Aerobic bacteria. These waters should also have fewer than 500 ppb of total organic carbon, fewer than 0.25 EU/ml endotoxins, and a conductivity of less than 1.3uS/cm @ 25 C.

Now that we have the textbook definition out of the way, we’ll spend the rest of this blog post delving a little deeper into WFI, how it’s made, and common pieces of process equipment used to make up WFI.

To begin, let’s start by looking at how Water for Injection is made. The USP allows WFI to be produced by one of two means; either distillation or reverse osmosis. Prior to making it to the still, however, supply water has to go through extensive pretreatment. Pretreatment usually includes various filtration steps, removal of chlorines through the use of activated carbon beds, and percolation of water through ion exchange resins to remove residual ionic compounds. What is the purpose of all this pretreatment? By pretreating the water, we effectively reduce the conductivity of the water, as well as the level of organic contaminants.
