As the kinetic parameters and short-term oxygen demands are functions of the compound undergoing biodegradation and the composition of the microbial community performing the degradation [11, 23], the respirometric method grants the possibility to assess the potential of activated sludge to oxidize different compounds and predict the rate of their removal in the treatment plant.
