Best available technologies of wastewater treatment: implementation experience of «Mosvodokanal» JSC
Summary
Owing to the transfer to process standardization from 2019 (Federal Law No. 219-FZ) natural resource users are bound to introduce the best available technologies. Advanced technologies of municipal wastewater treatment ensuring the removal of nitrogen and phosphorus have been used in Russia at less than 10% of the wastewater treatment facilities. When transferring to process standardization many water utilities will face the problem of upgrading wastewater treatment facilities. Successful practical experience of water utilities where BATs have been already used at wastewater treatment facilities will be useful for choosing the optimal process flow scheme. The introduction of advanced wastewater treatment methods has been a priority task for «Mosvodokanal» JSC. For a long period the company has developed and adapted to the conditions of the Moscow wastewater treatment facilities the process flow scheme of wastewater treatment with the removal of nutrients (nitrogen and phosphorus) which is the best available technology. This made it possible to introduce this technology at the Lyuberetskie and Kuryanovskie wastewater treatment facilities – the largest and extremely large-scale facilities as well as at small- and mid-scale wastewater treatment plants in Minzag and Shchapovo settlements (Prefecture of Troitsky and Novomoskovsky Administrative Districts, Moscow). Experts of «Mosvodokanal» JSC developed a pre-design concept of the reconstruction of the aeration tanks at the treatment facilities of Cherepovets and the local treatment facilities of the Optina Pustyn monastery (Kozelsk, Kaluga Region) with the introduction of nutrients removal technology. The practical experience gained in «Mosvodokanal» JSC shows that the best available technologies have been developed, can be introduced and operate successfully.
