Albatros MIS: Aerobic active sludge system with automatic sludge evacuation consisting of 2 or 3 tanks

  • Denomination MIS: Micro Individual Station
  • Range from 50 till 250 PE* and higher * PE: population equivalent
  • Covered by an international patent PCT/IB00/0566

This station works according the principle of the active sludge.
The system consists of 2 or 3 tanks. 
The first tank is the sludge storage tank, the second the micro station with the aeration and sedimentation compartment with sludge recalculation or for more 50 PE separated in an aeration tank and a sedimentation tank.
The wastewater enters in the first tank.
The second tank is the aeration/sedimentation tank (the micro station)
The wastewater is aerated in the aeration compartiment/bassin. The aeration is done by our patented immersed aerator (Int.Pat. PCT/IB/00566) for less than 50 PE.
The sludge built in the sedimentation room is automatically evacuated to the sludge storage tank, where it will be digested together with the primary sludge. The gases will be evacuated through the ventilation pipe.
The programming of the aeration time is possible in function of the number of PE.


  • The distance between the building and the wastewater plant is not of importance.
  • The plant is completely under ground and makes no noise.
  • The storage of the produced activated sludge is automatically.
  • Simply and efficiently.
  • Simply for maintenance.
  • Without expensive adjuvant and with minimal sludge treatment costs due to the long retention times and the  big  utile volume of the system
