Birds that have settled on the BSA outfall channel have a positive impact on water quality in Kyiv and the region.
The Bortnytsia Wastewater Treatment Plant treats wastewater efficiently due to many factors, including the presence of birds. The press service of Kyivvodokanal provided details.
The classical wastewater treatment scheme at the Bortnytsia aeration station involves biological and mechanical treatment. Wastewater that has already passed all the stages of treatment is discharged into the Dnipro River. This happens through the main canal where the birds have settled. A total of 600-650 thousand m3 of treated water passes through the canal per day.
The results of the analysis show that the most impartial experts are the wild swans that have settled on the BSA drainage canal. It is the birds that make it possible to obtain high water quality indicators.
Graceful and tidy swans never live in dirty water bodies, especially if they have a choice. This fact indicates that the wastewater treatment at the Bortnychi Aeration Plant meets all the necessary standards. Representatives of Kyiv’s fauna agree with this statement. In addition to swans, there are also ducks and other birds in the reservoir.
The water temperature in the canal never drops below 11-12 degrees. Experts hope that the birds will continue to perform an important function.
Bortnytsia aeration station
In Kyiv, the Bortnytsia Aeration Station operates under the jurisdiction of Kyivvodokanal. All domestic wastewater is treated at the station, as well as wastewater from industrial enterprises.The Bortnytsia aeration station purifies water not only through equipment and basic facilities, but also through birds.
The plant includes three wastewater treatment units, 3 auxiliary and sludge treatment shops. The facility uses a classical wastewater treatment scheme.
First, wastewater enters the intake channel of the rake section of the pumping station and then onto screens with mechanical rakes. Subsequently, the waste is retained on the screens, where it is collected by a conveyor into a special storage hopper. It is then transported to the Energia plant for incineration.
The main problem with this important facility is that the current wastewater treatment and sludge processing scheme was developed and designed by experts in the 50s and 60s of the last century. Since then, virtually no significant changes have been made to it.
The functional equipment has actually reached the end of its useful life. The service life of the equipment and main structures reaches 30-40 years. The metal and reinforced concrete structures of technological structures are constantly being destroyed, the main blower and pumping equipment is failing due to heavy wear, and technological pipelines are being damaged by corrosion processes.
In July, the National Energy and Utilities Regulatory Commission cancelled the decision to increase water tariffs.
