dc.description.abstractSeveral measures were taken to improve the effluent quality and the digestion process of the decentralised anaerobic-aerobic wastewater treatment plant “IWB Stöckacker Süd” with a two-chamber septic tank followed by 8 HRAR and an aerobic treatment. Structural and biological modifications have been carried out in the treatment plant to improve effluent quality and to avoid scum formation. The structural modification of an “InnerTube Digester” in the septic tank did not work due to high accumulation of scum and needed to be removed. Through adding specialised microbes from Bio-clean the structure of the scum in the septic tank could be changed to a better digestible one but total avoidance of scum formation was not achieved. Presents of solids wastes like wet wipes and tampons supported the formation of scum. Biological modification in the anaerobic treatment showed positive results in the septic tank and first compartment of the HRAR. An increase of CODrem rate from 42% to 66% was achieved. But effluent value from anaerobic treatment could not be decreased under 250mg/L COD because of hardly degradable compounds. Approaches in changing methane fermentation into dark fermentation were taken and the shift to dark fermentation could be recognized by increased VFA production. Biological modification with Bioclean TM in the aerobic reactor increased the CODrem rate from 50% to 65% and showed the presents of bio-flocs. An effluent COD value of 88mg/L was achieved by the combination of anaerobic and aerobic biological modification.de_CH
