MBR Membrane
Veolia ZeeWeed MBR Membrane is a reinforced hollow-fiber ultrafiltration membrane for submerged membrane bioreactor systems. A market leader for over 25 years, it delivers reliable performance in municipal and industrial wastewater treatment.

Veolia ZeeWeed MBR Membrane is a reinforced hollow-fiber ultrafiltration (UF) membrane designed specifically for submerged membrane bioreactor (MBR) systems. It has been a market leader for over 25 years, delivering reliable performance across municipal and industrial wastewater treatment applications.
Key Features
-
Reinforced PVDF hollow-fiber design provides exceptional mechanical strength (>600 N tensile strength), high fouling tolerance, and a typical pore size of 0.02–0.04 µm .
-
High permeability (>900 LMH/bar) yields high flux rates even under challenging raw water conditions.
-
Outstanding durability, with many installations operating well beyond a decade—some reaching over 20 years.
-
Robust oxidant resistance, capable of withstanding typical chlorine exposures in MBR cleaning regimes.
System Advantages
-
Compact MBR footprint: The submerged ZeeWeed system allows for process intensification, reducing plant footprint and optimizing layout.
-
Consistent high-quality effluent: The UF membrane ensures low turbidity, effective solids separation, and pathogen removal, making the system reuse-ready.
-
Energy-efficient operation: Compared to flat-sheet MBR designs, ZeeWeed hollow fiber systems significantly reduce aeration and energy needs, with next-generation models (500EV) offering up to 20 % energy savings and 50 % reduced membrane footprint.
Applications
-
Municipal and industrial MBR plants
-
Food and beverage wastewater treatment
-
Industrial wastewater reuse and recycling
-
Drinking water pretreatment and water reclamation
Proven Performance
-
Over 2,000 MBR installations worldwide use ZeeWeed 500 membranes.
-
The advanced ZeeWeed 500EV model offers increased membrane packing density, enabling more treatment capacity within the same footprint—ideal for retrofits and upgrades.
In summary, the Veolia ZeeWeed MBR membranes provide a reliable, compact, and energy-efficient UF solution for modern wastewater treatment and water reuse systems. Their proven durability and high-performance profile make them a preferred choice for projects requiring robust and scalable MBR technology.
