To remove urea and formaldehyde from synthetic wastewater, Campos and colleagues33 operated a coupled system consisting of a biofilm airlift suspension (BAS) reactor to carry out nitrification and an anoxic USB reactor to carry out the denitrification and urea hydrolysis (Figure 19.8). 

The main reactor types are upflow sludge blankets, biofilm fluidized beds, expanded granular sludge blankets, and biofihn airlift suspension and internal circulation reactors.
