Safety Precautions

Ozone is a powerful oxidizing agent. Observe
strict operating procedures while using ozone
equipment. It is imperative that only ozone com-
patible materials are used in conjunction with
the ozone system.
Note: If the oper ator has asthma, he or
she must not enter an airspace that has a
significant ozone concentration. Ozone can
induce an asthma attack.
Ensure that the Ozone Generator is in a well-
ventilated area. Do not allow rain or condensation
to contact the Ozone Generator. The Ozone Gener-
ator is not weather proof. The unit must be operat-
ed indoors or in an enclosure in a non-condensing
environment.
Carefully review and familiarize yourself with the
following important safety information concerning
the Ozone Generator:
1. Ozone is an extremely aggressive and power-
ful oxidizer. The Occupational Safety and
Health Administration (OSHA) 8-hour expo-
sure limit is 0.10-PPM. The OSHA 15-minute
exposure limit for ozone is 0.3 PPM. Above
0.3 PPM, there is the risk of damage to respira-
tory tissues.
2. People who have no sense of smell should not
operate this equipment.
3. Never attempt to verify ozone production by
directly breathing or smelling the ozone outlet
or the ozone-tubing outlet.
4. The Ozone Generator contains high voltages.
Unauthorized entry can result in serious injury
or death. For service instructions, contact
Ozone Solutions.
5. Make sure all tubing connections between the
Ozone Generator and the injection point are
secure and in good working condition. Failure
to do so could result in the discharge of ozone
into an undesired space.

Introduction

This Turn-Key Ozone Injection System is a pack-
aged ozone system that will generate ozone, inject
this ozone into water, and control all systems au-
tomatically. Ozone is generated using an Ozone
Generator to produce up to 100 g/hr of ozone.
This skid has a Control System to control all func-
tions of the Ozone Generator, and Ozone Injection
System automatically. Each of these functions will
be described in this manual. Please read and famil-
iarize yourself with this and other related Opera-
tion Manuals before use.

Theory of Operation

The purpose of this system is to use ozone as a
disinfectant for water. Ozone is a very reactive gas
that must be produced on site. Ozone in the gase-
ous form is also very unstable and difficult to
manage in an effective way for any reliable disin-
fection processes. Because of these factors, the
ozone is dissolved into water whereby it can be
applied effectively to the surface of any food
product or other item that may require disinfec-
tion.
The ozone is produced using a 100 g/hr Ozone
Generator. The Ozone Generator produces up to
100 g/hr of ozone from oxygen feed gas. This ox-
ygen feed gas is concentrated from compressed air
supplied by the internal oil-less air compressor.
The oxygen concentrator uses Pressure Swing Ab-
sorption (PSA) technology with a zeolite material
to purge the nitrogen from the compressed air
leaving 90-95% oxygen feed gas for the ozone
generator. This oxygen is passed through an ozone
generator cell which uses a controlled high volt-
age, high frequency spark called a corona to con-
vert as much oxygen (O2) into ozone (O3) as pos-
sible. The result is 5-8% ozone in an oxygen
stream of up to 46 SCFH leaving the Ozone Gen-
erator at pressures up to 15 PSI.
The process of converting oxygen into ozone is an
energy intensive process that generates a large
amount of heat. This heat must be removed from
the ozone generating cell for efficient and reliable
operation. The ozone generator in this system uses
a water cooled cell to remove this heat. This does
require constant flow of cooling water through the
cell to maintain sufficient ozone production.
