NEW TECHNOLOGY DEVELOPED
BY OXIDATION SYSTEMS, INC.
The USEPA sponsored TechKnow Database
recently highlighted the Oxidation Systems,
Inc. Pulsed Ozone Sparging Process
ozone sparging is a highly effective remedial
technology for treating contaminated soil and
groundwater in-situ. The process involves
injecting high-concentration ozone gas into
saturated soils to chemically oxidize VOCs,
SVOCs, chlorinated solvents, petroleum
hydrocarbons, and other organic compounds.
treatment system includes a compressed air
supply, oxygen concentrator, corona discharge
ozone generator, a manifold, and control system.
Concentrated ozone gas is directed to the
subsurface through a stainless steel manifold
using either stainless steel piping or
ozone-resistant tubing. Sparge wells are
installed throughout the target zone to deliver
the ozone gas to the contaminated soil or
groundwater. Automatic solenoid valves may be
used to cycle the injection of gas through the
sparge wells and to automate the process. This
may also be performed manually using standard
ball valves. The gas injection rate and pressure
must be determined for each site. Typically, the
injection gas flow rate is kept low to minimize
the potential for mobilization of contaminants.
This also eliminates the need for a vapor
