Innovative directions for the development of the Liuberetskie wastewater treatment facilities

Summary

The Moscow wastewater disposal system is a complex system of engineering structures; its reliable and efficient operation is one of the most important components of the sanitary and environmental well-being of the city. In order to comply with the environmental requirements of the legislation of the Russian Federation, Mosvodokanal JSC has been actively involved in the reconstruction and upgrade of the municipal wastewater treatment facilities in recent years. Currently, the implementation of a large-scale project for the comprehensive reconstruction of the Liuberetskie wastewater treatment facilities has been underway. Within the framework of the project introducing advanced energy and resource-saving technologies for wastewater treatment and sludge treatment is planned. Much attention is paid to the problem of removing odors from the wastewater treatment facilities. During the reconstruction of the Liuberetskie wastewater treatment facilities the following advanced technologies are being introduced: enhanced wastewater treatment with nutrients removal (nitrogen and phosphorus); removal of nitrogen compounds from reject water using Anammox technology and removal of phosphorus compounds to obtain a mineral fertilizer – struvite; thermal decontamination of wastewater sludge with the generation of finished products and their subsequent sale at cement plants as an alternative fuel; installation of covers and systems for vent emissions purification.

Summary

The Liuberetskie Wastewater Treatment Facilities have been the significant facilities of the Moscow wastewater disposal system that secure solution to the wastewater treatment tasks. In order to comply with the environmental requirements of the legislation of the Russian Federation, Mosvodokanal JSC has been actively involved in the upgrade and modernization of the municipal wastewater treatment facilities in recent years. Since 2019 the works have been in progress to implement a large-scale project for the comprehensive upgrade of the Liuberetskie Wastewater Treatment Facilities. To date, two stages of the reconstruction have been completed. As a result, the emission of wastewater odors into the atmosphere has been practically eliminated at the new facilities, the efficiency of mechanical wastewater treatment has been improved, and the high quality of effluent has been achieved including nutrients (nitrogen and phosphorus), so that the effluent quality meets the current process standards based on the best available technologies.
