Patent Pending Moving Bed Biofilm Reactor MBBR

What is MBBR? The Moving Bed Biofilm Reactor (MBBR) process is a biological process used for wastewater treatment for BOD removal, nitrification and denitrification. MBBR is a fixed-film (or attached growth) process servicing both municipal and industrial markets.

A MBBR consists of a tank with suspended plastic bio-media.  Due to the shape of the media there is a large surface area to assist with bacterial growth.  Oxygen for the process is provided through air spargers or lances installed at the bottom of the reactor which creates a positive Dissolved Oxygen (DO) concentration for Biological Oxygen Demand (BOD) removal.  A screen is placed around the outlet to keep the media within the reactor.  An Aerofloat DAF is normally placed downstream of the MBBR reactor to separate the suspended biomass which breaks off the bio-media.  Generally sludge recycle is not required for this process.

The Aerofloat MBBR Aerofloat’s patent pending MBBR technology is another world first, offering a simple, cost effective solution to traditional wastewater treatment methods.  The unique design of the spargers allows them to be removed from the reactor while the process is still operating, without draining the tank or removing the biomedia.

The Aerofloat MBBR and DAF together provide a complete wastewater treatment offering that can be tailored to your specific needs.  The DAF compliments the MBBR technology when placed downstream to remove the excess solids from the effluent and to thicken excess biomass prior to disposal.
