ZWAR, Bergen auf Rügen.
Recovery of ammonium and relief of the biological treatment installation.
At the sewage treatment plant on the island of Rügen, the ammonium is recovered and converted into a valuable fertilizer
The effluent from the digester of the Bergen auf Rügen sewage treatment plant creates a major load on the biological water treatment plant. This required an extension of the biological system. Byosis has an alternative solution for this by integrating the ByoFlex® ammonia stripper.
By removing and converting the ammonium from the effluent from the digester with the ByoFlex® technology, the biological treatment installation of the sewage plant is now fed with effluent with >70% less nitrogen. Especially valuable in summertime when the load is high during the tourist season.
The system is easy to start up and shut down. When the sewage load is low in wintertime the installation can be stopped but is direct available on demand.
The installation reduces the nitrogen load of the biological treatment. Additionally, this creates a valuable circular process. The recovered nitrogen is, as ammonium sulphate, reused by the farmers on the island as a fertilizer. This creates a significant reduction of the use of artificial fertilizers on the island.
