ZeeWeed Ultrafiltration

Description and Use

As a pioneer of membrane technology, Veolia leverages decades of research, development, and operational experience in developing one of the most advanced pressurized ultrafiltration technology in the market, ZeeWeed 1500. 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 pressurized ZeeWeed ZW1500 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
