Although the size of pollutants discharged to a WWTP plays an important and often underestimated role in characterizing treat ability and hence the degree of contaminant removal of wastewater. From one hend In order to obtain efficient nitrogen removal in thedenitrification process, sufficient amounts of bioavailable carbon source should be ensured bur for the other hand in TWs, particulates from the wastewater are naturally trapped by filtrationand can cause clogging. The investigations carried out bring information about factors and conditions influencing (limiting) COD and N fractions removal and transformation in the changing condition of SSVF and SSHF beds. The investigated MTW in Wiklino ensured astable and very effective removal of all the analysed pollutants. Based on the achieved results it could be assumed that the working condition of SS HF beds play an important role in the transformation of particulate to colloidal and colloidal do dissolved fractions of organic matter and Org-N. The SS VF bed was very effective in the removal of the dissolved fraction, which can suggest that very effective microbiological processes take place in it. The investigation proved that part of particulate organic matter and Org-N present in raw wastewater is resistant to treatment.
