Abstract : A sewage sludge digestion system consisting of anaerobic (ANA) digestion followed by aerobic (AER) digestion
step was studied to determine the impact on solid and nitrogen removal. It was found that the combined ANA/AER system
provided higher solid and ammonia removal compared to conventional single ANA digestion with a 32 day SRT. In this study,
an efficient Total Solid (TS) and Total Kjeldahl Nitrogen (TKN) removal in ANA/AER system was measured higher
compared to single AN system. In ANA/AER system, TS and TOC reduction rates were observed 29 and 32%, respectively,
while the TKN removal increases to 50%. This finding shows ANA/AER system as an alternativetechnologi in wastewater
treatment.
