Recover ammonium from thin fraction with ByoFlex
The biogas plant of 3B-Energie GmbH, owned and managed by the Schulte Siering family uses the ByoFlex® technology to recover ammonium from the thin fraction of their digestate. Besides the ByoFlex® tests are also being carried out on the removal of phosphate.
3B-Energie is limited in spreading the liquid fraction in the surrounding fields. The plant is situated in a livestock-rich environment with a surplus of nutrients of animal origin, therefore part of the nitrogen from the digestate must be transported to areas with shortages. Or it must be converted to a different form of fertilizer.
By removing and converting the ammonium from the liquid fraction with the ByoFlex® technology, 3B-Energie obtains a liquid fraction low in nitrogen and a high value nitrogen rich fertilizer.
This allows3B-Energie to spread more over the surrounding fields with more flexibility as to how and when to spread.
The plant processes 40.000 tons of substrates each year, generates 2 MWe of renewable electricity and an equivalent amount of heat. The ByoFlex unit was expanded in 2018 with a lime dosing unit, a flocculation unit, a phosphate reactor and a decanter to further increase the stripping efficiency, reduce the DM-content and phosphate level of the thin fraction. Phosphate is also a limiting parameter in the area (surrounding fields) in addition to nitrogen.
