scope:

This Standard stipulates general specification items 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 stipulates those treatment apparatuses with a maximum ozone generation capacity of at least 0.5 kg/h.

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.
