Ozone: an effective corrosion controller.

Author(s) : O'BOYLE R. V.

Type of article: Article

Summary

A large HVAC plant, (three 4835 kilowatt-chillers), in New York has suffered corrosion problems in the cooling towers and condenser water systems since installation in 1983. The article describes the programmes of tests and treatment systems based on recognised chemical methods that have failed over the years. New methods of analysis disclosed the major problem to be bacterial rather than chemical, the solution probably requiring a strong oxidizing agent. Ozone was tried, generated by a corona discharge and injected by a venturi system. Subsequent checks have shown this to be overcoming the corrosion. D.W.H.
