ZeeWeed* pressurized ultrafiltration
model ZW1500
Description and use
As a pioneer of membrane technology, veolia leverag-es decades of research, development, and operational experience in developing the most advanced pressur-ized ultrafiltration technology in the market, ZeeWeed 1500. ZeeWeed systems are proven to consistently outperform conventional filtration technology while meeting or exceeding regulatory requirements, re-gardless of source water quality.
typical applications
Versatile and reliable, the pressurized ZeeWeed 1500 is ideally suited for use in numerous applications including drinking water treatment, tertiary filtration and 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
storage and handling
Modules may be stored in the original factory pack- aging for up to 1 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 sources of heat, ignition, or direct sunlight (UV light).
