ASSESSMENT OF NITRIFICATION - DENITRIFICATION POTENTIAL OF ISTANBUL DOMESTIC WASTEWATERS

This paper summarizes experimental evaluations on Istanbul domestic wa stewaters with respect to their potential of biological nitrogen remov al. Characterization studies involve together with relevant carbonaceo us and nitrogenous wastewater components, significant rate coefficient s affecting aerobic and anoxic processes. Experimental results indicat e a low biodegradable carbon to nitrogen ratio and a relatively small readily biodegradable COD fraction, A new method is introduced to dete rmine maximum specific growth rate for autotrophic biomass. Correction factors for biological growth and hydrolysis under anoxic conditions are also assessed, The latter is found to be significantly higher than values proposed in the literature.
