Typical Layout of an Ozone Injection System

Many configurations had been developed and tried and there may be further variations in the design of a turn-key ozone injection skid but in general the principle is fairly similar. Here we will attempt to outline the major components of the system.

Using the corona discharge ozone generator and the oxygen concentrator (oxygen fed  ozone generator), the ozone injection skid typically follows the line process by which the ambient air is first circulated through the air dryer (the ambient air must be sufficiently dry and free of moisture in order to be used as a feed for the oxygen concentrator).

Ozone for Soil and Ground Water Remediation (In-situ ozone sparging).

BTEX is a common acronym used to describe benzene, toluene ethyl benzene, and xylenes. BTEX compounds are some of the most commonly VOC (volatile organic compounds) found in petroleum derivatives such as gasoline and are often found as a persistent contaminants in the areas prone to gasoline and gasoline derivative spills (old gas stations, gasoline storage yards, refineries, etc.).

The inherent danger of BTEX is that toluene, ethyl benzene, and xylenes are very toxic substances with the documented history of harmful effects on the central nervous system. Because of the solubility of the majority of the BTEX components they are also prone to leaching into the underground waterways therefore polluting much wider area than the original contamination site. As such the decontamination of soils and ground water contaminated with the BTEX traces is strongly recommended.
