ZeeWeed Submerged Ultrafiltration Membranes Veolia Suez
Veolia’s submerged ultrafiltration (UF) portfolio offers two distinct solutions designed for different treatment challenges:
ZeeWeed 500D UF membranes represents the pinnacle of membrane engineering with its reinforced Polyvinylidene Fluoride (PVDF) fibers. With an industry-leading fiber strength of 600N, it offers unmatched solids tolerance that eliminates the need for pre-treatment. This innovative design allows direct filtration of high-solids waters, making it the most robust ultrafiltration solution available.
ZeeWeed 1000 UF membrane is optimized for large-scale municipal applications, particularly in drinking water and wastewater tertiary filtration. Its submerged design operates under vacuum, enabling creative hydraulic configurations that minimize energy consumption and simplify operations. The system’s compact footprint delivers significant total cost of ownership benefits through reduced real estate requirements.
ZeeWeed submerged systems leverage vacuum-driven operation to maximize energy efficiency and operational flexibility, setting new standards for sustainable water treatment

ZeeWeed 500 UF Membrane
The ZeeWeed 500 ultrafiltration, hollow fiber, reinforced membrane provides customers with high-performance, energy efficiency, and proven membrane life. The ZeeWeed 500 membrane gives customers the flexibility to treat any flow rate without the need to upfront clarification or pre-treatment.
ZeeWeed 500 UF Membrane Benefits
- Highest solids tolerance of any hollow-fiber membrane
- Works through virtually any raw water quality change or upset
- Outside-in flow path provides a more robust system
- Outstanding solutions for virtually all wastewater treatment applications — from greenfield plants to retrofits to water reclamation projects
- Second stage to obtain higher recoveries
ZeeWeed 1000 UF Membrane
ZeeWeed 1000 membranes produce superior water quality and are virtually unaffected by variable raw water quality — all at a cost comparable to conventional filtration options. A solution utilizing ZeeWeed 1000 membranes combines extreme footprint intensity with low operating costs for a membrane filtration solution with unmatched total life cost efficiency.
ZeeWeed 1000 UF Membrane Benefits
- Flexible: cassette design allows for cost-effective retrofits of filter basins of different shapes and sizes.
- Compact: bookshelf style arrangement of membrane modules up to 4 high, making the ZeeWeed 1000 membrane flow to footprint ratio best in class.
- Simple: Large building block design simplifies operation due to fewer process components and connections.
- Gentle: immersed membranes operate on a vacuum, reducing energy and chemical costs over alternative filtration options.
ZeeWeed Submerged Ultrafiltration Membranes Veolia Suez
Water often contains particles, bacteria, and viruses that make it unsafe for drinking and unsuitable for industrial use. ZeeWeed submerged ultrafiltration membranes remove these contaminants while maintaining essential water minerals.
In submerged ultrafiltration, membrane fibers are immersed directly in the water to be treated, arranged in cassettes within a tank. A gentle vacuum draws water through the microscopic pores of the membrane, effectively filtering out unwanted particles and micro-organisms while allowing clean water to pass through. This simple but effective design works like a very fine filter, producing high-quality water suitable for drinking or further treatment.
What makes submerged ultrafiltration particularly efficient is its flexible operating approach. The system can run using traditional pump suction, or in many cases, can operate purely through natural siphon effect — using gravity to drive filtration. This innovative use of hydraulics significantly reduces energy consumption and operational complexity while maintaining superior filtration performance.
