U.S. EPA Superfund Innovative Technology Evaluation
(SITE) Program CAV-OX® Process Magnum Water Technology (4,380KB)
ABSTRACT
The Cav-OX® uses hydrodynamic cavitation and ultraviolet (UV) radiation to
oxidize organic contaminants in water without the release of volatile organics
to the atmosphere. UV radiation generates free radicals that, along with cavitation,
degrade organic contaminants. Hydrogen peroxide and metal catalysts can be added.
Halogenated solvents, pentachlorophenol (PCP), BTEX compounds (benzene, toluene,
ethylbenzene, and xylenes), cyanide, bacteria, and viral strains can reportedly
be treated. The technology was demonstrated for 4 weeks in March 1993 at Edwards
Air Force Base in California. Groundwater flow rates (from a storage tank) ranged
from 0.5 to 1.5 gpm. The cavitation chamber (no UV radiation) provided removal
rates between 61.7 and greater than 99.9 percent. With UV radiation, the Cav-OX®
process achieved removal efficiencies that ranged from 78.7 to greater than
99.9 percent. In both cases, hydrogen peroxide concentrations ranged from 4.9
to 48.3 mg/L. Removal efficiencies decreased with increasing flow rates and
removal rates increased when a 10kW UV lamp was substituted for a 5kW lamp.
