Ecosim™: what is it?

Ecosim combines two well proven processes from Veolia Water Technology portfolio: the PMT Ecodisk and the Anoxkaldnes MBBR, in order to ensure the optimal treatment of Carbon & Nitrogen related pollution.

With a simple and reliable approach, Ecosim offers high performance at low operating and maintenance costs. 


Ecosim™ is a biological wastewater treatment system that automatically adapts itself to frequent hydraulic and organic loading variations.

Its operating principle is inspired by a moving bed biofilm reactor (MBBR) : bacteria naturally grow on the surface of the rotating media to form a "bioturf". 
When the drum emerges, the bacteria consumes oxygen, and when it is submerged, bacteria consumes dissolved organic matter.

The crucial difference between a conventional MBBR process and Ecosim™ is the aeration source.

Conventional MBBR systems need air blowers to supply the adequate O₂ into the system. Therefore systems’ electrical consumption is generally high. 

By using the rotation of the drum for the aeration, Ecosim™ offers a much more energy-efficient solution.

Some possible implementation examples :

While keeping the benefits of an Ecodisk, Ecosim offers even a more sustainable approach thanks to the :

  • Advanced treatment performance
  • Reduced CO₂ emissions
  • Minimized footprint
  • Limited transportation costs
  • Optimized electricity consumption

Solar Option

Coupled with solar panels, Ecosim becomes Ecosim Solar, an even more sustainable approach, to accompany our customers on the path for the Ecological Transformation.
