Nadezhdinsky Metallurgical Plant is ready to launch effluent treatment facilities for the contaminated circulating water that comes from the blast furnace gas cleaning system.
After this facility is revamped, water intake from the Kakva river will be reduced. Fresh water will be consumed only to fill up the circulating water and pollutant discharge will be lessened.
‘This programme is part of the Agreement signed with the Government of the Sverdlovsk Region and now we are gradually implementing it,’ says Olga Trenikhina, Head of the Environmental Management Office. ‘Our company takes consistent nature conservation efforts. The legislation instructs us to reduce amounts of effluents and pollutant discharges and increase waste recycling volumes and this is actually what we are doing. Revamping the blast furnace gas cleaning system is one of the steps that we take to lessen environmental emissions.
This facility will be ready for start-up by this July. Today, the commissioning of the hydraulics is underway in this facility: all pumps and valves are being inspected.The control, instrumentation and automation networks and computers are being tuned and configured. The equipment is being tested in the conditions that are similar to the actual operating environment.
It should be mentioned that the currently existing effluent treatment facilities have been in operation for over 50 years. The following stage in revamping the circulating water circuit of the blast furnace gas cleaning system will be to convert the blast furnace gas cleaning system to the zero-discharge water supply system. It is scheduled to be completed by 2020.
