The role of colloidal and particulate organic compounds in idenitrification and EBPR occurring in a full-scale activatedsludge system

Abstract

The aim of this study was to determine the immediate effects of slowly biodegradable substrates on the denitrification capability andphosphate release/uptake interactions for a full-scale biomass process from the ''Wschod'' wastewater treatment plant (WWTP) in Gdansk (Poland). Since it is hard to distinguish the slowlybiodegradable substrate in a direct way, a novel procedure based on batch experiments was developed and implemented. The laboratory experiments were carried out in two parallel, fully automatic batch reactors with the settled wastewater without pretreatment and after coagulationflocculation. The removal of colloidal and particulate fractions resulted in the reduced observed process rates, such as denitrification, phosphate release and phosphate uptake (under aerobicand anoxic conditions). The reduction ranged from approximately 14% for the anaerobic P release to approximately 46% for the anoxic P uptake.
