Abstract:
The condition of activated sludge, which predetermines the efficiency of functioning of purification facilities, depends to a great extent on a toxicity degree of waste-waters coming for purification. The results of a study of toxicity of effluents of an industrial enterprise by using the methods of the chemical-and-analytic and toxicological monitoring are described in the article. The conducted investigations made it possible to specify an effluents' flow, which is most toxic for the activated-sludge microorganisms, for the purpose of its further localization.

Biological Treatment of Effluent and Waste Water
Biological wastewater treatment relies on the metabolic activity of microorganisms to remove pollutants from sewage. In modern treatment systems, this process is organized into sequential stages that progressively reduce solid material, dissolved organic matter, and microbial contamination. Each stage plays a distinct role in improving water quality and preparing the effluent for safe discharge or reuse.Primary and Secondary TreatmentPrimary treatment is a physical process that removes large...
Microbial Wastewater Treatment
Microbial communities in aquatic ecosystems play a key role in the natural breakdown of contaminants introduced through domestic and industrial effluents. Acting as biological catalysts, these microbes change and mineralize a wide range of organic and inorganic pollutants under different redox conditions.In oxygen-rich surface waters, aerobic heterotrophs lead organic matter breakdown, using oxygen as the terminal electron acceptor to efficiently oxidize substrates to carbon dioxide and water.
