The biologically biodegradable waste water from the Leverkusen Chempark and the households of the lower drainage basin for the Wupperverband (Wupper association) is cleaned by Currenta in a community waste water treatment plant. The aeration of the open basin has been carried out since 2007 by centrifugal compressors from Atlas Copco, which replaced the classic surface aerators.

“Our basin biology in the Leverkusen community waste water treatment plant needed an overhaul from the ground up, after 40 years of operation,” Norbert Meier-Külschbach explained. He is a waste water department engineer at Currenta, and is responsible for the engineering of three waste water treatment plants in Leverkusen, Dormagen, and Uerdingen, Germany. The disposal of biological biodegradable waters, originating from households as well as from chemical processes, is an important task for Currenta. “Our plant cannot be compared with either classic industrial waste water treatment plants or typical community waste water treatment plants,” Meier-Külschbach said. This makes it difficult to compare the biological purification potential or energy consumption with other plants.
