  • Nitrogen removal from ammonium rich wastewater by nitrification and dentrifiction using an activated sludge
    Jurkovič, J... ...
    Nitrogen removal from higly loaded wastewater was investigated. An activated sludge of several bacterial strains showing high nitrification activity was used in the experiments. The continuous ... nitrification/denitriifcation rate in a bench scale reactor was 59 g Nkg/ biomass d-1 with the addition of methanol , and 55 gN/kg biomass d-1 with the additon of sodium acetate. The acivated sludge also reduced the COD by more than 90%. The results show that methanol could be an appropriate carbon source with the peak activity achived at ratio C:N = 2. The high nitrification rate and the low C:N ratio and the use of methanol as the carbon source make the process economically interesting.
