Peristaltic pumps for moving filtration water
The Eversburg sewage treatment plant is designed to serve 250,000 population equivalents. But in 2005, its actual load was closer to 309,000 population equivalents (COD 80 mg/l), pushing the nitrogen input level above the plant''s capabilities.
To deal with this situation, engineer Peter Sikora organized a team to develop a process-based alternative to biological elimination of nitrogen. The pumps moving filtration water into the nitrogen elimination plant are a critical aspect of the concept. In 2006, the plant began using Allweiler peristaltic pumps as an alternative to the centrifugal pumps from another manufacturer.
