The project entailed the acquisition and implementation of 4 state-of-the-art vertical filters that replaced the existing 26 filters. The investment increases energy efficiency by reducing electricity and natural gas consumption and improves the company’s sustainability by reducing industrial water consumption and emissions.
In addition, the automation of the entire filtration process improves the overall safety of the employees’ activity and offers more control over the filtration process, having a direct effect on increasing the quality of alumina by reducing impurities in aluminate liquors, the company said.
“Transforming the filtration unit into a state-of-the-art one represents the latest investment in process automation, improving control over our activities and increasing product quality to exceed our customers’ expectations,” said company general manager Gheorghe Dobra.
Alum plans to continue its sustainable development program, production optimization, growth and increased competitiveness through a new stage of the investment program, which is scheduled for the period 2021-2025.
Alum is the only Romanian producer of calcined alumina, used for the production of aluminum and has an alumina refinery with a production capacity of 600,000 tons of alumina per year. The alumina produced by the company is supplied both on the domestic market to ALRO S.A., part of the Vimetco Group, and internationally.
