Membrane Aerated Biofilm Reactor is a unique attached growth biofilm (fixed film) aeration system which allows for low energy delivery of oxygen from the carrier side. The MABR system increases the performance and stability of the activated sludge plant and creates an ideal environment to support a very resilient biofilm that can withstand hydraulic shock loads and process upsets. 

The biofilm absorbs and consumes carbon- and nitrogen-based pollutants, but unlike conventional fixed film/biofilm systems (MBBR, RBC) it is incredibility energy efficient. 

Key benefits:

• Incremental increase in biological treatment capacity, up to 50% 
• Up to 75% less energy consumption on additional capacity 
• Up to 50% reduction in waste sludge
