Abstract
Abstract The lack of sufficiently effective treatment of wastewater generated in industry and domestic life remains one of the most acute environmental problems. Domestic wastewater is characterized by a high content of organic impurities in its composition, which determines the specifics of the choice of treatment technologies. One of the most relevant and effective methods is biological purification carried out in biological filters. This article discusses the problems associated with wastewater treatment of a sanatorium compound. The analysis of the content of various components in the water supplied to the treatment was carried out, the efficiency of the treatment equipment was determined. The paper proposes and substantiates the expediency of using a modern type of synthetic ruff biofilter media to increase the cleaning efficiency of the wastewater and their compliance with regulatory requirements for discharge into a water body.
