An MBBR reactor is an aerobic biological process in which the degradation of organic matter is carried out by aerobic bacteria inside a moving bed biological reactor. Moving bed MBBR reactors use biofilm-covered plastic carriers to break down organic waste. These carriers, also known as carriersare submerged in the biological reactor and, through their movement, increase the performance and purification capacity of the MBBR system without increasing the size of the reactor. This type of system is commonly applied in places where the available space is limited, since it allows reducing the required volume of the aeration chambers with respect to conventional activated sludge systems, while maintaining the same treatment performance.
