The water ozonation station control system performs the following tasks:
maintenance of appropriate- resulting from the technology of air parameters for pre-ozonization (temperature, humidity, pressure) – for both initial and intermediate ozonation,
maintaining the appropriate ozone concentration in the pipeline supplying water to consumers,
warning system that warns about exceeding the ozone concentration in water and in the air in the control room,
the use of separate controllers for the main devices (ozone generators and dryers) ensures more reliable operation of the entire water ozonation station.
