Production Mode
Dose Control
With this control mode, in addition to the main setpoint Ozone Dose, another constant setpoint
must be specified: Ozone Concentration or Gas Flow Generator.
Depending on the Required Ozone Mass, the non-constant setpoint is changed variably in order
to produce the Required Ozone Mass. The Process Water Flow is the reference variable for
determining the required mass.
