EVRAZ ZSMK: Pollution Discharge Down 900,000 m2

31 October 2019 (14:44)

UrBC, Yekaterinburg, October 31, 2019. EVRAZ Holding’s West-Siberian Integrated Metallurgical Plant (EVRAZ ZSMK) reduced its pollution discharge in the Konobenikha River by 900,000 m2 in 2019 compared with one year earlier thanks to the plant’s water conservation program for 2017-2022.

The plant’s PR Department reports one step they took was reduce sweet water spending at the rail and beam department’s pumping station. The station used to replace the warm manufacturing water from the rolling mills with cold water from the river. This is no longer necessary: following an assessment of the cooling agents and of the construction costs, a mechanical-draft tower was put up. The station now needs less sweet water and the rail and beam department discharges no pollutants into the water.

‘The modern mechanical-draft tower supplied by the Italian company Decsarus runs on variable-frequency drive control systems, which ensures automatic adjustment of the ventilating appliances’ running speed, depending on the temperature, and helps control the cooling range for the manufacturing water. The entire process is fully automated, the only time an operator is needed is during the launch. The mechanical-draft tower is also fitted with water meters to control the water spending. The information is also displayed on the rolling mill stand’s operator panel screen,’ the company says.

EVRAZ ZSMK adopted its Water Protection Program for 2018-2020 in order to ensure greater environmental safety at its production sites. Under the terms of the program, the company will reduce its overall discharge by 12m m3 and its pollution discharge by 3,000,000 kg by 2022.
