Treatment of VOC in Waste Gas by UV-Oxidation

VOC (Volatile Organic Carbon) can efficiently be treated by means of UV-Oxidation. two different concepts can be applied:

- Reaction scrubbers with integrated UV-Oxidation

- Scrubber and UV-Reactor are separated

The choice depends on various parameters and also the legal limits in the washing water.

The process is always based on an increase of the hydrophilic character of the organics by the UV-Oxidation. As OH-, O= and HOOC- groups are inserted into the VOC water solubility increases by the UV-treatment and the modified VOC can be scrubbed with washing water. After successful gas washing, a further Oxidation by UV or AOP, depending on additional requirements can be processed.

The advantages can be clearly seen:

- compact technology

- simple in terms of automation

- sterile system as bio fouling is blocked by UV-irradiation

- easy to maintain
