As is well known without organic matter, there would be no life. Organic compounds perform very important functions in the whole ecosystem as: structural, storage, transport, catalyse reactions, immune and regulatory functions. One of the most important for both living and non-living organic matter is their role in the biogeochemical cycles of carbon, phosphorus, nitrogen and others elements. The major form of organic matter are humic substances (HS) which are a mixture of high molecular weight organic compounds with variable composition. Humic substances can be divided into: humic acids (HA), fulvic acids (FA) and humins (Hu). In the presented research FA were studied. They were extracted from the effluent in the process of ion exchange in a hydrophobic ion exchanger and then they were examined by qualitative analysis to determine the elemental composition of acids and the degree of contamination with heavy metals and other substances. The main aim was to balance and assess the amount of FA in the primary and secondary effluent. The studies have shown that concentration of FA in raw wastewater (primary effluent) was bigger than in the treated wastewater (secondary effluent). Based on the research, it can be stated that selected WWTP discharges less FA compared to the input pollution load.
