ATLANTIS® submerged MBR

The ATLANTIS® MBR is our Membrane Bio Reactor technology designed for the treatment of larger wastewater flows or wastewater not requiring harsh and frequent cleanings of the membranes. It produces an effluent that is extremely pure and appropriate for immediate reuse.

At Waterleau, we have several wastewater treatment plants using ATLANTIS® MBR technology, in the industry as well as for municipal wastewater treatment.

Submerged MBR

In an ATLANTIS® MBR, reinforced hollow fibre membranes are submerged in the bioreactor for the separation of sludge and biologically purified wastewater. The membranes in the bioreactor are kept clean by means of an efficient coarse bubble aeration which ensures a good sludge management in the membrane module and guarantees turbulent conditions at the membrane surface.


  • Low in energy consumption
  • Very compact installation (size reduction factor 3).
  • Perfect solution for revamping or increasing the capacity of existing wastewater treatment plants
