Pfizer Green Facility Uses Ozone for Water Purification

Pfizer Biotechnology Ireland has constructed the Monoclonal Antibodies (MAbs) Small Scale Facility (SSF) at Shanbally, Ringaskiddy, Co. Cork, Ireland. The facility serves to establish a strategic biotechnology manufacturing center of excellence and is planned to support the rapid development of new biotechnology products.

Utilizing best practice and Pfizer’s Green Building guidelines, a large number of energy efficient features were applied in the design. As well as items which were commonly applied across the majority of utility systems, specific measures undertaken include economizers on boilers, heat recovery from blow down to pre-heat make-up water, automatic oxygen trim, gas boilers and low NOx burners, and all condensate systems are designed for the return of condensate to a central receiver/deaerator. Cooling water systems were designed such that the RO waste water stream, regeneration and reject, can be used as feed-water for make-up. For clean water system sanitization purposes, ozone is used on RIW (Reduced Ion Water) rather than heat/steam, and final treatment on purified water systems is electro-deionized, with meters provided to monitor all water use. Point of use coolers are utilized rather than loop coolers.
