MBR (Membrane Bio Reactor) was marketed in the 1990s. It was started to a small wastewater treatment plant at first. After then, MBR market spread to large–scale municipal wastewater treatment plant.

In the future, MBR targets various next generation technologies, for example effective utilization of the MBR’s activated sludge biomass.
