that target ressource-efficient wastewater treatment following the credo of „doing more, in less, with less“.
One common feature is the enhancement of biological activity by using physical selectors for biomass-enrichment. The light and fragile flocs in the AAA-process are captures by gravimetric settling, bio-P-activated sludge is densified by a hydro-cyclone (inDENSE) and anammox-granules are selected by a microscreen (DEMON).
The brand ‚DEMON‘ stands for ‚Deammonification‘. The combination of aerobic and anaerobic ammonia conversion in a single reactor allows energy efficient nitrogen removal from high-strength ammonia wastewater. The core features of DEMON are the pH-controlled aeration to maintain …
