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.

Oxygen Fed Ozone Generators versus Ambient Air Fed Generators – Which technology is right for you?

Corona discharge ozone generators typically fall into the two categories ( based on the feed gas used to generate the ozone). While some require purified oxygen, others claim to be able to operate using an ambient air feed. What are the main differences between the two and which one is the right choice for you?

Oxygen Fed Ozone Generators:

Oxygen fed ozone generators typically require an additional component called the oxygen concentrator.

Pressure Swing Adsorption (PSA) – The typical layout of the PSA Oxygen Concentrator.

In order to yield the higher volume ozone output typically required for the industrial ozone applications, your ozone generator must be designed to accept a gas feed containing a significantly higher concentration of oxygen than what is readily available om the ambient air.

Since the typical composition of ambient air is 21% oxygen and 78% nitrogen, the most economical way to increase the concentration of oxygen in ambient air is to remove the nitrogen component from it.
