What is Water For Injection (WFI)?

How does water quality for injectable pharmaceuticals (known as Water For Injection or ‘WFI’) differ from other classifications of pharmaceutical-quality water? What do water supply system engineers/water system designers need to know when designing feed-supply water systems and pre-treatment processes in the pharmaceutical manufacturing sector?

Questions such as these are answered in our online GMP education course for the pharmaceutical manufacturing sector, PMF104 – Pharmaceutical Water Systems.

The Water for Injection (WFI) component of the Pharmaceutical Water Systems Course is one fo the pharmaceutical industry education topics available online. You can take this single Certificate Course for Pharmaceutical Water Systems or complete the entire four-part series.

Water for Injection (WFI) of a 4-part series on pharmaceutical manufacturing fundamentals, covers the fundamentals of Pharmaceutical Water Systems designs, water quality testing and system validation processes, including Water for Injection (WFI).

Background of Pharmaceutical WFI and industry courses

Pharmaceutical Water Systems, including information on Water for Injections (WFI) and other water quality system information, is part of the four-part series: Pharmaceutical Manufacturing Fundamentals (PMF). This 4-module e-learning series suits Pharmaceutical Industry professionals, including engineers and hospital teams. These courses will provide a foundational learning induction to the pharmaceutical manufaturing sector including WFI water quality and system designs.

These online PICS GMP regulatory compliance courses are best utilised when combined with blended learning solutions including onsite training, other GMP courses and relevant Annexes (such as Biological Manufacturing), and other learning modalities.

Our pharmaceutical manufacturing education options include courses on:
