ZeeWeed 500 Membrane Bioreactor

The ZeeWeed 500 Membrane Family

Veolia’s immersed ZeeWeed 500 membrane is specifically designed for difficult-to-treat water sources. Wastewater, water reuse, and industrial applications can all benefit from Veolia’s strongest ZeeWeed membrane to produce water with very high purity and low silt density.

With more than two decades of membrane design experience, Veolia has optimized the ZeeWeed 500 membrane to improve flux, achieve greater permeability, reduce energy consumption, and increase membrane lifespan.

ZeeWeed MBR combines conventional biological wastewater treatment with advanced membrane filtration to deliver superior quality effluent. 

In this innovative process, our specialized ZeeWeed UF hollow-fiber membranes act like microscopic sieves, filtering out solids while allowing clean water to pass through. 

Unlike traditional treatment systems, ZeeWeed MBR eliminates the need for secondary clarifiers and tertiary filtration, making it more compact and efficient. The ZeeWeed UF membranes are submerged directly in the biological treatment tank, where beneficial bacteria break down waste while the ultrafiltration membrane fibers capture and retain suspended solids and microorganisms. This results in consistently high-quality treated water that’s suitable for reuse or safe environmental discharge, all while requiring up a fraction of the space needed for a conventional treatment plant.
