  • A convincing alternative to surface aeration: patented submersed stirrer
  • Fine bubble aeration due to mechanical air bubble dispersion (coarse air bubble input under the mixing unit)
  • No danger of blockage, membrane-breaking or reduction of oxygen capacity
  • “Mixing” (denitrification) and “Aeration” (nitrification) are possible as alternatives
  • High ground speed prevents any settling at the tank bottom
  • Oxygen input capacity: up to 120 kgO2/h per unit
  • Oxygen efficiency up to 2.5 kgO2/kWh. Alpha (α)-value ca. 0.9 (domestic wastewater)
  • Nearly maintenance-free gear-drives (only one oil change every year)
