scope:
This Standard stipulates general specification items (performance requirements) for ozone treatment apparatus (hereafter referred to as treatment apparatus) used in such areas as industrial water and wastewater, sewage water and drinking water, as well as the methods of ozone concentration measurement.
This Standard is applicable to treatment apparatuses with a rated ozone generation capacity (total generation capacity if the apparatus consists of a series of ozone-generating processes) of 0.5 kg/h or greater.
The method for calculation of this capacity is provided in Annex A.
NOTE A treatment apparatus is used for the purposes of destruction of organic substances and trace toxic substances, disinfection, and decolouring and deodourizing. The apparatus consists of a series of processes or units, including ozone generation, ozone contact, and ozone destruction at ozone concentration control points (hereafter referred to as process control points) where ozone concentrations are properly measured and controlled.
