Fact Sheet ZeeWeed* Immersed Ultrafiltration Model ZW1000-SW Description and Use As a pioneer of membrane technology, GE leverages decades of research, development, and operational experience in developing one of the most advanced submerged ultrafiltration technology in the market, ZeeWeed 1000. ZeeWeed systems are proven to consistently outperform conventional filtration technology while meeting or exceeding regulatory requirements, regardless of source water quality. Typical Applications Versatile and reliable, the ZeeWeed 1000-SW (Figure 1) is ideally suited for use in RO pre-treatment for brackish water and seawater. Compared to granular filter media, ZeeWeed membranes produce superior water quality and are virtually unaffected by variable raw water quality – all at a cost comparable to conventional filtration technology. General Properties • • • 0.02 µm nominal pore diameter - for optimal removal of particulates, bacteria and viruses PVDF hollow fiber membrane - provides high mechanical strength and chemical resistance Outside-in filtration - provides uniform flow distribution and high solids tolerance Figure 1: ZeeWeed 1000 Seawater module Storage and Handling Modules may be stored in the original factory packaging for up to one year prior to installation. Modules must be stored between 5°C and 35°C (41°F to 95°F). Do not expose the membrane module to direct sunlight (UV light). The module housing and other plastic components may degrade with extended UV exposure.
