Humic-like substances (HA) were extracted from sludge from three sewage treatment plants with dif­ferent treatment technologies. Investigations of the extracted humic-like substances (HA) were carried out by means of elementary analysis and spectroscopic methods. Results of elementary analysis show that the percentage content of nitrogen is different for HA ex­tracted from sludge derived from the subsequent treatment stages. The influence of the treatment process on nitrogen content also was observed. The percentage content of nitrogen was of the range from 5.05% to 8.99%. The highest value of nitrogen for HA extracted from sludge was obtained from the nitrification and denitrification chamber. The spectroscopic methods confirmed the presence of nitrogen functional groups.
