Description Générale

The Computer Controlled Advanced Oxidation Unit "POAC" generates hydroxyl radicals (OH-) through ultraviolet light radiation with hydrogen peroxide.

Raw water is enriched with hydrogen peroxide in a transparent tank and is driven by a pump towards a reactor where an ultraviolet lamp with protective tube is lodged.

The reactor has manifolds at its upper part that allow the flow of raw water forming a falling film on the inner walls of the reactor. As it descends, it receives ultraviolet light radiation, forming hydroxyl radicals, which oxidize non-biodegradable soluble substances from the water to be treated.

The reactor is open by its upper side. Water flows towards the tank, forming a closed circuit. A flow sensor allows to measure the raw water flow rate through the circuit.

Des exercices et pratiques guidées


  1. Study of advanced oxidation process for wastewater treatment.
  2. Study of advanced oxidation with hydrogen peroxide and UV light.
  3. Influence of the amount of hydrogen peroxide in the oxidation process.
  4. Analysis of the reaction kinetics.
  5. Sensors calibration.


  1. Many students view results simultaneously. To view all results in real time in the classroom by means of a projector or an electronic whiteboard.
  2. Open Control, Multicontrol and Real Time Control. This unit allows intrinsically and/or extrinsically to change the span, gains: proportional, integral, derivative parameters, etc. in real time.
  3. The Computer Control System with SCADA allows a real industrial simulation.
  4. This unit is totally safe as uses mechanical, electrical/electronic, and software safety devices.This unit can be used for doing applied research.
11.- This unit can be used for giving training courses to Industrieseven to other Technical Education Institutions.12.- Control of the POAC unit process through the control interfacebox without the computer.13.- Visualization of all the sensors values used in the POAC unitprocess.- By using PLC-PI additional 19 more exercises can be done.- Several other exercises can be done and designed by the user.
