MSC slashes water consumption to 3.8 m3 per ton

Ever since Mobarakeh Steel Company (MSC) was founded, one of its strategies has centered on optimal use of water. Development of state-of-the-art water treatment facilities and implementation of recycling initiatives in the production cycle have always been a priority.
That line of thinking along with an organizational culture which has overseen the implementation of several projects has slashed water consumption for each ton of hot-rolled sheets to 3.8 m3, which is an all-time record for MSC and is unprecedented among steelmakers, both local and foreign.
Mohammad Hassan Rahimi, who heads the Energy and Fluids Department of the giant steelmaker, said the achievement is the result of the emphasis by top MSC management on contribution by all personnel to efforts to cut water consumption as well as various projects which have drawn a lot of investment. The decline in water consumption is going full steam ahead.
He listed the following as some of the measures MSC has taken to make optimal use of water resources and cut consumption levels: treatment and recycling of wastewater and reuse of treated water in the production process; use of low-quality wastewater produced in some processes to cool slag and slabs and thus slash the volume of industrial water consumption; completion of a project to collect and transfer the wastewater of nearby towns, including Mobarakeh, Zarinshahr, Safaiyeh, Varnamkhast, etc.; launch of the first phase of a project to treat industrial wastewater through reverse osmosis and introduction of high-quality water to the cooling process with industrial water; replacement of flora inside the premises of the company with plants that require little water to thrive; improvement of the water cycle in cooling towers through injection of antiscalant and anti-corrosion chemicals in a bid to increase the water cycles; modernization of the system that transfers and distributes industrial and fully-treated water inside the company premises; development of the facilities that treat both human and industrial wastewater in a bid to improve the quality of treated water and reuse it; preliminary studies to prevent water from going to waste in cooling waters and in the direct reduction process; and organization of a contest in which personnel put forth their suggestions on how water consumption could be slashed and water use optimized.
