Wąsik, Ewa | Chmielowski, Krzysztof
The paper discusses the effectiveness of removing ammonium ions and indicator bacteria from domestic sewage in a vertical flow filter filled with a plastic material (PET flakes). Preliminary research has shown the effectiveness of ammonium nitrogen removal at the value of 66.74%. Principal Component Analysis was used to determine the mechanism of the removal of indicator bacteria. Three principal components were identified and they were responsible for 78,2% of input data variability. PCA analysis showed, that the effectiveness of Escherichia coli removal depended mainly on the filtering mechanism. In the case of coliform bacteria removal an additional factor was acidic conditions. A decrease in CFU of the coliform bacteria by one order of magnitude was observed at pH=4.1.
