The aim of the study was to determine the effect of the Actinomycetes proliferation in the activated sludge on the quality of the treated wastewater and the sewage receiver. The river which is the sewage receiver flows near the wastewater treatment plant. The study was performed on the wastewater (raw and treated) and on the river water samples (collected before and after wastewater discharge). The analysis of the research results, such as the content of total organic carbon (TOC), total phosphorus and oxygen consumption in the examined samples, permit the conclusion that the presence of relatively large population of the Actinomycetes in sewage sludge has a negative impact on the quality of the sewage receiver. Determining the effect of the Actinomycetes in the activated sludge on the wastewater treatment process involved the application of specific analyses, such as Sludge Biotic Index (SBI) and the identification of filamentous bacteria in the activated sludge. The analysis of studies indicates that the presence of the Actinomycetes in the activated sludge adversely affects the efficiency of the wastewater treatment process.
