Abstract
The article is dedicated to determine the α-factor of aeration systems in case of changing the wastewater treatment line (transfer of aeration tanks to the nitri-denitrifier aeration mode). The studies were performed on an experimental installation with sewage and activated sludge at one of the sewage treatment facilities of the Udmurt Republic. During the process of determining the parameter under consideration, pure water and the sludge mixture from the experimental plant were sequentially aerated at the same conditions; thus, the KLα was sequentially determined for two different types of liquids. The ratio of different liquids defined under the same conditions of KLα determines the α-factor. Plate aerators with a dispersing element made of a rubber membrane were used as an experimental plants, thanks to which a high calculated value of the α-factor was found - 0.95 ± 0.03.
