| Abstract: | A fully automated system is controlling a two-stage ozonation system treating 140 × 103 m3/h (6.4 mgd) of potable water in a full-scale water treatment plant. A supervisory computer has a data communications path to each of six ozone generators and a direct link to the ozone destruct system. Total ozone requirement is calculated, the most power-efficient equipment configuration is selectedt and the flow of ozone to each contactor is controlled. Inaddition, graphic display ofequipment status and process variables is provided system events are logged, and strip charts and reports are produced. |
