Final Decision to Certify Hazardous Waste Environmental Technology TriOx Ozone Treatment System for Cooling Tower Water Certification No: 94-01-007 Technology Description: TriOx manufactures an ozone treatment system which replaces chemical biocides with a computer controlled continuous ozonation system for control of biological growth in cooling towers. The management of water from cooling towers generally includes the control of biological fouling, microbially induced corrosion, and pathogenic bacteria. Traditional industry practices for the control of biological growth in cooling towers, include the addition of chemical biocides. Chemicals used for this purpose include compounds, such as glutaraldehyde, tributyltin oxide, quaternary ammonium salts, or other organic or inorganic compounds. Publicly Operated Treatment Works (POTWs) regulate discharge of blowdown from cooling towers. POTWs have increasingly restricted discharge of contaminants in blowdown water to their sewer systems. The TriOx system uses water from the cooling tower. Ozone is dissolved into the water using a patented static mixer. Ozone as a biocide is not intended to replace anti-scaling or corrosion control measures. Where it has been determined that such measures are appropriate, the TriOx ozone system may be used in conjunction with their reverse osmosis system and/or other ozone-compatible anti-scaling or corrosion control methods.
