Annotation: The article is devoted to the research of the of the sludge index’s dependence on the load on activated sludge according to BODp at sewage treatment plants in a number of settlements of Donbass, operating at low loads. As a result of the research, it was found that in the range of loads on sludge from 25 to 180 mgBODp / (g In addition, it was determined that in the specified range of loads, provided that the main technological parameters of the biological treatment process are maintained at the required levels, the sludge index is mainly in the range from 80 to 130 cm3 / g, i.e., activated sludge retains good sedimentation properties, which allows for an efficient biological treatment process.
Keywords: wastewater, biological treatment, activated sludge, sludge index, load on activated sludge according to bod.
