VIZ-Steel has replaced its treatment facilities equipment

VIZ-Steel (part of NLMK Group) has overhauled and put into operation one of the four filter presses in its water treatment facilities unit – the centrepiece of the company's closed-loop water recirculation system.

A filter press is designed to dewater sediments that settle during the treatment of wastewater coming from the cold rolling shop lines. Treated water will be reused in the company's closed-loop water recirculation system.

An overhaul of the treatment facilities involved replacing 15 water treatment filter plates and fine-tuning the electric drive, pistons and the oil pump station. Replacing the filter press components, the company will reduce the risk of unscheduled treatment facility downtime by 25%, improve the performance of its Mg-containing wastewater treatment system and operational stability of the cold rolling shop lines.

VIZ-Steel allocated about ₽14m for the overhaul of its filtration equipment.
