Ufa, 14 March - Neftegaz.RU. Mechel reports that Beloretsk Metallurgical Plant (BMK, part of Mechel Group) launched new ecological equipment in its high-strength wire workshop. The upgrade enabled the plant to stop using acid in wire production, bring industrial waste effluents down by 8 times and ensure high-level effluent treatment. The Bashkortostan’s Prime Minister Rustem Mardanov attended the launch ceremony.
The new facilities were launched as PM Rustem Mardanov, Mechel CEO Oleg Korzhov and BMK’s CEO Viktor Kamelin pushed a symbolic button. After, the delegation toured the workshop’s industrial waste disposal plant where new waste water cleaning equipment was installed.
BMK began implementing the project of rejecting acid pickling in favor of best available technologies in 2015 as part of its agreement with Rosprirodnadzor branch. The plant invested some 200 million rubles into the project. 2 new facilities produced by Italy’s Promostar are the project’s final stage.
The new equipment descales steel rod mechanically using scale breakers. During the descaling process, the rod 1st goes from the unwinding equipment to special rolls that clean off large scales thanks to bending. Small scale is then cleaned off the surface by metal wool. Before, the rod was descaled by acid.
The new technology completely excludes several water waste sources formed during acid descaling and the following washing of the rod. Today, the workshop’s waste water volume is down 8 times, from 2,400 to 300 cubic meters a day.
Before the new facility’s launch, the workshop has been prepared by shutting down the acid department, reconstructing drawing benches and installing a new water pump intake and a waste water treatment equipment that ensures industrial and stormwater effluents’ compliance with ecological norms.
«This is a major event not only for the plant and the city, but for the entire republic. The plant’s transfer to this new technology not just minimizes, but completely eliminates negative ecological impact on Bashkortostan’s chief water artery, the Belaya River,» Bashkortostan’s Prime Minister Rustem Mardanov noted.
