MBBR Pack: what is it?

MBBR Pack is a wastewater treatment system developed within Veolia Water Technologies. It was initially developped in 2015 by Anoxkaldnes / Evaled collaboration and it's included to PMT product range at the end of 2019. One of the important aspect is that MBBR Pack proposes both Anoxkaldnes expertise on MBBR systems and PMT expertise on standard product manufacturing and related services in a container.


MBBR Pack is easily a moving bed biological contactor unit in a standard container.

MBBR Pack working principle is quite simple but also efficient. The main tank is filled with Anoxkaldnes MBBR carriers. The bacteria attach on the surface media to form a biofilm. The consumption of pollutant load in aerobic and/or anaerobic conditions contributes the bacterial growth on biofilm surface. The excess biomass will detach automatically by movement within module.

Depending the model, there are different aims and also equipments :

  • AE-AE : Fully aerobic model of MBBR Pack has been designed to encounter maily C and NH4+ sources pollution. The whole container is equipped by an equily distributed fine air diffuser system which ensure good repartition of oxygen.
  • AN-AE : Main compartement is divided into two parts to ensure the C removal, nitrification and also denitrification.
  • AN-AN : Fully anaerobic module equipped with efficinet mivxers especially dedicated for TN removal with the help of denitrification.

After the degredation of the organic matter, a last step enables the clarification of water before rejecting it into the environment. Depending on the specifications of the community or operator, this clarification can be based on a lamella filter, a drum filter or filtration by reed plants.
