Controlling Hazardous Conditions in Ozone Rooms

Architecture & Building Services, Insights and Resources

Ozone is becoming increasingly popular, quickly replacing chlorine as a disinfectant in water treatment plants because of the many advantages it offers. Though it is highly toxic and dangerously reactive, ozone has greater disinfection effectiveness than chlorine against bacteria and viruses. This paper will review ventilation as an effective method of controlling the hazardous conditions involving ozone. The upgrade project at the Holmedale Water Treatment Plant in Brantford, Ontario, designed by R.V. Anderson Associates, includes an ozone facility for disinfection and utilizes the ventilation system. Other than proper ventilation, good engineering practices must also be applied to control the hazardous conditions in ozone rooms.
