  • Page 7: Presentation Of The Instrument

    OZONMAT 9185 - INSTRUCTION MANUAL Presentation of the instrument Introduction The oxidative properties of ozone are used for disinfecting water in a large number of industrial installations. Continuous monitoring of dissolved ozone levels is therefore essential in order to guarantee the bacteriological quality of water.
  • Page 8 OZONMAT 9185 - INSTRUCTION MANUAL for example, for an ozoniser generating a concentration of 2 g/m , the maximum concentration X in water, at P = 1 atm, will be as follows: T°C (ppm) 1.28 0.78 0.62 0.48 0.38 0.24 It appears that this concentration is divided by 2 between 5 and 20 °C.
  • Page 9 OZONMAT 9185 - INSTRUCTION MANUAL The presence of air in the conduits The exposure to free air of highly ozone-loaded water results in significant degassing: as the ozone content of ambient air is very low compared to that of the sample, exchange therefore occurs, with rapid loss of ozone in the sample.
  • Page 10 OZONMAT 9185 - INSTRUCTION MANUAL Measurement principle Measurement is performed using the amperometric method, after diffusion of ozone molecules through a gas permeable membrane. Ozone measurement is based on the Clark cell principle. This amperometric sensor is made up of: - a gold work electrode where the main reaction occurs, - a silver counter-electrode, - an electrolyte, which is an ionic conductor,...
  • Page 11 OZONMAT 9185 - INSTRUCTION MANUAL The ozone molecules contained in the sample diffuse through the membrane. O is therefore located in a very thin electrolyte layer between the membrane and the cathode. A constant work potential is applied to the work electrode (cathode) where O is reduced to oxygen.
