EVRAZ ZSMK has launched a new slurry thickening facility for the gas cleaning equipment at its blast furnaces. The new equipment will reduce annual wastewater discharge and water intake from the Tom River by nearly 3 million cubic metres.
Previously, the water that was used to purify blast furnace gases was sent to the plant’s slurry storage facility. Now, it is sent to a machine that separates and thickens the slurry. The clarified water is re-used in production, closing the blast furnace shop’s water supply cycle.
In 2019, EVRAZ ZSMK plans to install similar equipment at its second basic oxygen furnace shop, which will reduce annual water intake by another 1.5 million cubic metres. This will effectively close the water supply cycle for the plant’s main metallurgical conversion facility.
A fish diverter has been installed at the on-shore pumping station to help safeguard young fish in the Tom River water intake.
The on-shore pumping station supplies water to the West Siberian Thermal Power Plant. Previously, fish were frequently harmed in the water intake. Now, a dual-stage fish diverter helps to prevent this. The first stage is a fine screen that does not allow large or medium-sized fish into the pumping station’s intake chamber. The second stage is an electronic system to keep young fish away. An electrical pulse is sent through electrodes at a certain amplitude, creating an electrical field that diverts fish from the intake chamber and back into the river.
