Abstract
An improved system for treatment of cooling tower water using ozone as a biocide. A self-contained unit is supplied with compressed air which is introduced to ozone generating electrodes at a constant flowrate. The ozone is mixed with tower water and then returned to the cooling tower. A sampling probe allows for constant monitoring of the ozone content of water coming from the tower. The volume of ozone mixing with the tower water is accordingly constantly adjusted. The system also includes safety control features to monitor system operation and provide shutoff in the event of malfunction.
Claims8
An ozone production electrode assembly comprising first outer and second inner tubular electrode elements mounted concentrically to each other to form a tubular air gap therebetween;
- a dielectric tube concentric with said electrode elements mounted therebetween within said air gap whereby a dielectric-electrode air gap is created between the outer surface of said dielectric tube and the inner surface of said first outer electrode element;
- a first stepped end cap at a first end of said first and second electrode elements and said dielectric tube having means for introducing oxygen-bearing gas into said dielectric-electrode air gap and for supporting said electrode elements and dielectric tube in a concentric relationship;
- and a second end cap at a second end of said first and second electrode elements and dielectric tube having means removing gas including ozone formed by the electrode assembly from said second end when an ozone-creating potential is placed across said first and second electrode elements and for supporting said electrode elements and dielectric tube in a concentric relationship, said gas introduction and removing means each being in the form of a passageway network through the respective end cap, each of said passageway networks having a first end at the exterior of said respective end cap and a plurality of second ends within said tubular air gap, the diameter of each of said second ends being proportional to the distance of said each of said second ends from the respective first end.
