Mechel Group’s refractories manufactures Mechel Materials has improved process water treatment in the sump of the fireclay shop. This reduces the load on water bodies. A sump is a special tank where water from the workshop for the production of refractory bricks for metallurgy enters. After being used in the process, the water contains clay and other suspended particles that settle in the sump. Several times a month, special machines collect sediment that has settled on the bottom of the tank and sewage wells. This improves water purification and increases the volume of the sump.Also, the water is filtered using a special device - a skimmer. Oils and other oil products stick to the equipment belt, after which the oil scraper cleans them and collects them in a separate container. Purified water is returned to the production cycle.
