GENESYS™ WFI is our world leading Water for Injection (WFI) purification unit, used worldwide in the pharmaceutical, research and medical applications to facilitate the production of WFI complying with all relevant pharmacopeia standards.

Water for Injection (WFI) generated by GENESYS™ WFI is used in bulk in the preparation of medicines for injectable administration and for applications where the water is used as a vehicle or to dissolve or dilute substances or preparations for injectable administration before use. It can also be integrated with steam generators provide pure steam.

Key components

Softened water tank

This 316L stainless vessel is used as a reservoir for sanitisation and can be used for the automatic CIP cycles.

Reverse osmosis

RO technology involves using a variable speed pressure pump to force a portion of the feed water through semi-permeable membranes. The permeate flow is kept constant, independent of variables such as the feed water temperature.

Continuous electro deionisation

The water passing through the CEDI is deionised to Purified Water using an electric current. The concentrate water exiting the CEDI unit is reused and mixed with the RO feed water.

Ultraviolet irradiation/ultrafiltration

The pure water exiting the CEDI passes to a UV unit or a 6,000 NMWL Ultrafilter to give added security in achieving the Purified and Highly Purified water specifications.

Credentials

Puretech engineered and installed a purified water to system at the AstraZeneca Research and Development Centre, Cambridge , taking raw water from the mains through purification using OASYS™ units. The purified water, which is stored in a 5000-litre tank, is distributed via a stainless-steel ring main to user points in the laboratories.
