The AquaDom aquarium is the biggest freestanding cylindrical aquarium in the world. It is home to 1500 fish and corals of 97 different species. All its 1000 m³ of water are recycled every hour in order to maintain the appropriate water conditions for sustaining life. Due to
the recirculation of the water and the ineffectiveness of their phosphate removal filter, the level of phosphate had risen above the desired concentration (

An fully automated akvoFloat pilot plant treated a water flow of 0,7 m³/h ( 17m³/d) from March to November 2014. Both Al2O3 and SiC ceramic membranes were tested.


It was the best phosphate removal ever achieved in AquaDom“ (Christian Wander – Operator )

  • High removal efficiency of phosphate (90%)
  • High recovery (> 97%)
  • 10 days of stable unmanned operation
  • High flux (183 lmh)
  • Low pressure drop (0,1- 0,25 bar)
