IPEM - Semi-industrial pilots

Practical work carried out on semi-industrial pilots

These teaching conditions are very close to the actual operating conditions of the processes as well as to the classical dysfunctions observed in industry. Students are thus faced with non-ideal facilities.

 

Aerobic biological treatment

This pilot simulates an urban or industrial wastewater treatment plant and operates with an activated sludge process. Continuous instrumentation and monitoring ensure that the process is monitored.

Sensors

  • Dissolved Oxygen Sensor
  • pH probe
  • Flowmeter inlet effluent

Control

  • Sludge Recycling
  • Ventilation by bubbling
  • Adjusting pH
  • Input rate

Handling

  • Measurement COD, MES, BOD
  • Monitoring of sludge quality
  • Evaluation of oxygen transfer

Membrane treatment

This pilot has three different membrane cartridges to illustrate the operation of various fine and very fine separation processes. The reverse osmosis and nanofiltration cartridges show the interests of both in the separation of salts and water. The ultrafiltration cartridge is used in industrial projects for treatment tests.

Sensors

  • Conductivity sensors
  • Pressure gauges
  • Inlet and outlet flowmeters

Handling

  • Monitoring salt concentration
  • Comparative study OI and NF for monovalent and divalent salts
  • Modeling of permeate flows

Physico-chemical treatment

This pilot simulates the operation of a primary treatment by coagulation and flocculation, followed by a lamellar decantation. The experiments are carried out on bench-top in a first time then on the pilot to apprehend the change of behavior between laboratory tests and full-scale operations.

Sensors

  • Flowmeters
  • Turbidity sensor

Handling

  • Tests in jar test to optimize the doses of coagulant and flocculant
  • Driver override with scaling
  • Evaluation of the effect of different parameters on the quality of treatment

Ion exchange treatment

This pilot simulates the treatment of effluent or salt water by ion exchange in order to understand the phenomena of exchange (drilling front) and to visualize the problems related to the regeneration of resins after use.
The process is applied to desalination of water.

Sensors

  • Conductivity sensors
  • Inlet and outlet flowmeters

Handlign

  • Measurement of the resin exchange capacity
  • Monitoring salt concentration in operation
  • Effectiveness of regeneration






 

Electrodialysis treatment

This electromembrane pilot is equipped with a dialysis membrane. It has three compartments and can be used in different types of process. Its application is carried out on the regeneration of acid and base solutions from saline solutions. The effects of pressure, current and concentrations are studied.

Sensors

  • Pressure gauges
  • Conductivity sensors
  • Flowmeters

Handling

  • Regeneration of acid and base solutions from saline solutions
