Membrane Aerated Biofilm Reactor (MABR) is a process intensification technology that upgrades activated sludge plants in a simple, fast & energy efficient manner. It is increasingly being applied as a cost-effective solution to expand capacity and improve nutrient removal performance of facilities in the US and globally.

Join Veolia, the Central Contra Costa County Sanitary District (Central San), and HDR to hear firsthand the results of an MABR pilot completed for secondary process intensification to remove nitrogen while maintaining a low 1.2 day bulk Solids Retention Time (SRT). MABR has the potential to reduce capital costs for the construction of new aeration tanks and clarifiers to meet regulatory limits.
