A new dimension in MBBR technology

20 October 2014

Veolia Water Technologies has launched a new generation of biofilm carriers for moving bed biofilm reactors: AnoxKaldnes Z-MBBR.

The new carrier is the result of two decades of development work.

Christian Rosen, one of Veolia’s Process Specialists explains: “Many biological processes use several different types of bacteria all needing different environments. Our challenge was to produce a biofilm carrier that could provide those different micro-environments so as to encourage the growth of selected bacteria. We can do that by precise control of the biofilm thickness which eliminates variations in performance and removes the limitations associated with clogging of the carriers.”

Unlike conventional MBBR carriers, Z-MBBR has a unique three-dimensional contoured structure that allows the creation of a self-controlled, pre-determined biofilm thickness on the carrier. This gives a controlled redox gradient and maximises mass transfer. Veolia’s Z carriers are customised to give biofilm thicknesses ranging from 200µm for fully aerobic processes like nitrification to 500µm for applications like Veolia’s ANITAMox ammonox denitrification system, which require aerobic, anoxic and anaerobic conditions on the same carrier.

Veolia’s first Z-MBBR full-scale plant is currently under construction and will be fully operational by the end of 2014.
