MBBR STP
MBBR STP is a type of wastewater treatment technology created by Prof. Hallvard degaard at Norwegian University of Science and Technology in the late 1980s.
MBBR is a biofilm process. This technology is essentially the same as Activated Sludge Process (ASP) except that the media suspended in the reactor offers additional surfaces for the microbes to grow and this in turn maximizes the growth of microbes in a given volume of aeration tank compared to the conventional aeration without the media and to that extent, it does appear preferable. MBBR system is often installed as a retrofit of existing activated sludge tanks to increase the capacity of existing system. Diffused aeration is also required. FAB technology
is akin to MBBR except that instead of the media in suspension, the media is kept stationary and fluidized in the aeration tank.
