PIGNAT Automated Biological Treatment – TAE3000




Demonstrate the various stages of wastewater treatment through the reproduction of the activated sludge process in an automated system.

Study of the sewage treatment process:

  • Strictly aerobic
  • Aerobic and anoxic by aeration syncopating
  • Aerobic and anoxic in separated basins

Conduct the process of wastewater treatment:

  • Called activated sludge treatment
  • Process monitoring
  • Search for optimal treatment parameters


  • Alarm management
  • pH and O2 control
  • Sludge recycling management
  • Production of polluted water

Proposed experiments:

  •  Study of the purification with aerobic treatment:
    • Treatment efficiency calculation (COD, BOD5).
    • Optimization of operating parameters (aeration, extraction and recirculation of sludge).
  • Study of nitrogen treatment:
    • Treatment of nitrogen in separated anoxic basin or by syncopating of aeration in the aerobic tank.
    • Treatment efficiency calculation (COD, BOD5, nitrate).
