Photozone Destruction of Cyanide Waste at Tinker AFB (Pilot Plant Results)

PHOTOZONE ACTIVATED OXYGEN consists of ozone (66.7%), hydroxyl radical (14.7%), hydrogen peroxide (5.9%), atomic oxygen (4.4%) and nitrogen oxides (0.1%). Activated Oxygen is generated by passing ambient air over spectrally controlled ultraviolet lamps in the range below 190 nanometers. The specifications for activated oxygen generator are the subject of patents in the U.S. and Europe.

Tinker AFB conducted pilot tests of the PHOTOZONE ACTIVATED OXYGEN System on its cyanide waste in September and October 1985. These pilot tests will provide information for the full scale system budgeted for installation in early 1987.

The economics for the proposed system are compared with alkaline chlorination addition.
