Abstract
<jats:title>Abstract</jats:title> <jats:p>Results of the studies for determining fractions of organic contaminants in a pretreated petrochemical wastewater flowing into a pilot Aerated Submerged Fixed-Bed Biofilm Reactor (ASFBBR) are presented and discussed. The method of chemical oxygen demand (<jats:italic>COD</jats:italic>) fractionation consisted of physical tests and biological assays. It was found that the main part of the total <jats:italic>COD</jats:italic> in the petrochemical, pretreated wastewater was soluble organic substance with average value of 57.6%. The fractions of particulate and colloidal organic matter were found to be 31.8% and 10.6%, respe...
