High Performance Digester



The heart of the plant is made of glass lined steel (standard system) or stainless steel (compact system).

The sludge flows through the digester from the bottom to the top forming a plug flow. An automatic discharge system at the floor level allows for continuous operation without needing to periodically empty the digestion chamber for sediment removal. The impulse pump, together with the perforated sheets, ensures a gentle local mixing of the sludge bed.


  • Hybrid Impuls Mixing (Impuls pump: 30 s, unpowered 150 s). WIthout moving part for the mixing.
  • < 0,5 kWh per m3 sludge (Conventional: <4 kWh/m3)
  • Up to 7-12 kg/m3 per day (Conventional> 2-3 kg/m3*d)
  • 6-10 days (Conventional> 15-40 days)
  • 4-7 % for sewage sludge, <14% for food waste 
  • No surface foam (plug flow reaction with high content of anaerobic bacteria at the substrate input zone of the digester bottom)
  • No floor sedimentation. Discharge from the bottom cone.
  • Full automatic control
