specific treatment after anaerobic sludge digestion to remove nitrogen – Cleargreen™
The Cleargreen™ is a deammonification allowing the treatment of concentrated ammonia caused by anaerobic digestion of sludge at the head of the station.

Limiting the impact of digestion on the water treatment line.

The CleargreenTM is designed to work with a biological sequencing batch reactor (SBR), allows the successive completion of all treatment phases in the same tank.

key figure

  • 60% less air needed compared to classic activated sludge treatment

among references

  • Burgos (Spain) - 150,000 m3/d
  • Ourence (Spain) - 350,000 PE
profit
  • Refurbishment: avoids to overload the water line
  • New plant: avoids to oversize the biologic treatment
  • Automation of process control
  • Robust adaptability to variations in load and effluent composition
  • Spontaneous installation of the biomass
  • No reactive agents needed
  • Automatic regulation of air supply= control of consumption
