Common Questions, Problems and Pitfalls

The short answers in this list only provide an overview of the aspects to be considered. Details will be found in the cited Chapters or Sections of this book. 

Ozone generator (EDOG) Is it possible to produce every cGo desired at constant 0G No. this depends on the EDOG operation characteristics. Choose an appropriate generator B 2.2.1.2 Fig. 2-2 

Ozone reactor. Is it possible to use PVC Yes, but it is only recommended for waste water experiments. B 2.1, B 2.1.2 

Ozone reactor off-gas Can the ozone containing off-gas be handled in a safe way Yes, a vent ozone destructor is necessary several types are available. Beware of explosive mixtures of 0J02-gas and certain organics. B 2.5 

Off-gas ozone destruction Is it also necessary to have an ozone destructor in the system when using an ELOG Yes, ozone can desorb from the water being ozonated due to over-saturation and appear in the reactor off-gas. B 2.5

This chapter provides some essentials about the individual components and how they affect ozonation. First the material of the equipment necessary for containing ozone (B 2.1) is examined, followed by the equipment for producing it (B 2.2), and bringing the reactants together (B 2.3). Methods to measure ozone, with their advantages/disadvantages (B 2.4) and the safety aspects to consider (B 2.5) are then discussed. This is rounded off with a list of common questions, problems and pitfalls that we have come across over the years (B 2.6). Perhaps it will be helpful to read before starting your own experiments.
