The authors investigated COD fractionation according to the physical state (soluble/colloidal/particulate) in four wastewater treatment plants (WWTPs) in northern Poland. It was found that particulate and colloidal organic compounds constituted up to 70% of total COD. On the other hand, according to literature data, municipal wastewater contains readily and slowly biodegradable substrates in the amount of approximately 10-30% and 40-60% of total COD, respectively. The effects of the readily biodegradable COD fraction in BNR systems have been well reported in literature, but it is still very little known about the particulate and colloidal (slowly biodegradable) substrates and their influence on denitrification and EBPR.
