8 Ozone extraction
8.1 What is ozone?
Ozone is a gas that is formed during the process of corona discharge and plays an important part in
the chemical and molecular changes that takes place in the surface of the plastic.
Ozone is hazardous to health and has an unpleasant smell, even at relatively low levels. The average
human can smell ozone at 0.01 ppm. and the threshold of safety of the gas in the area occupied by
personnel is 0.1 ppm. All of VETAPHONE's equipment is therefore designed to remove ozone
effectively from the treater station by means of an ozone-protected fan, and a specially designed
exhaust system.
An option instead of ducting the ozone through the roof to the atmosphere is to use an ozone
eliminator. This is an independent, catalytic filter system that accelerates the decomposition ozone,
eliminating it completely.
