Dissolved Ozone Monitor/Controller
A dissolved ozone monitor/controller may be used
to ensure that the water is completely charged
before starting the timing of the cycle, as well as
providing a continuous monitor for observation.
In addition, it is used to control the ozone system
so that the tank of water can be maintained
continuously and stays charged at the level
determined by the adjustable set-point; it will vary
the ozone system production as needed to maintain
the set point.
The dissolved ozone monitor leaves the DEL
Ozone facility programmed with a 2.0 ppm set
point. This setting may be adjusted to suit your
specific sanitation needs.
The AGW skid includes the dissolved ozone
sensor (probe) which must be prepared before use.
Refer to the included Ozone Monitor manual for
information on this procedure, calibration, adjusting
of set points, and general operation information.
Indigo Blue Ampules with Colorimeter (Hach
AccuVac Test Kit)
This method can be used to determine the amount
of ozone at the discharge of the CIP (at the end
of the cycle). It cannot be used to determine
the amount of ozone in the ozone charge tank
because the highest range of detectability is 1.5
PPM. Therefore, refer to the Ozone Tank Charging
Guidelines, charge the ozone charge tank for the
proper amount of time and then begin the CIP.
After 30 minutes, test the discharge water with the
Hach AccuVac Ampule. If there is 1.0 - 1.5 PPM
ozone in this discharge water, it can be safely
determined that the system is sanitized.
4E-1. CIP (Clean In Place)
Refer to the Ozone Tank Charging 1.
Guidelines. Determine the amount of water
in the ozone charge tank. Operate the
AGW–4015/4025/4045 for the proper amount
of time based on the amount of water in the
ozone charge tank, and charge the water to
approximately 3 PPM. The time necessary to
accomplish this is dependent on the volume of
water in the tank. Once the water is charged
with 3 PPM ozone, CIP operation can begin.
Experience dictates that 15 - 30 minutes of
CIP operation with an applied dose of 3 PPM is
an acceptable amount of time to attain a zero
microbial count. A longer duration will not cause
any harm. Individual preferences vary, but 30
minutes is the recommended optimum.
General Tank Sanitation - See page 3, drawing
2.
3B. Wash debris and rinse the tank with clean
water. Connect the AGW–4015/4025/4045
to the tank and recirculate the system while
spraying with any standard spray ball.
Approximate spray time is 15-30 minutes.
4E-2. Facility Washdown
Refer to the Ozone Tank Charging Guidelines.
Determine the amount of water in the ozone charge
tank. Operate the AGW–4015/4025/4045 for the
proper amount of time based on the amount of
water in the ozone charge tank, and charge the
water to approximately 2-3 PPM.
The time necessary to accomplish this is
dependent on the volume of water in a given tank.
Once the water is charged with 2-3 PPM ozone, a
spray rig can draw this ozone charged water from
the ozone charge tank.
CAUTION: Maximum pressure 22 psi - higher
pressure will result in excessive ozone off-gas!
The spray can be directed on floors, drains, walls,
wettable equipment, external or internal tanks,
clean rooms, etc. (If the ozone spray is being
applied in a very small, enclosed, poorly ventilated
area, it may be necessary to wear a standard
ventilator to avoid the inhalation of ozone gas.
Breathing exposure to greater than 0.1 PPM ozone
gas can irritate eyes and sensitive lung tissue.
Please see the Safety Section 7 for further details
and a Material Safety Data Sheet on ozone.)
Based on industry experience, the amount of
time necessary to attain sanitation depends on
the amount of debris found in the area to be
cleaned. Sweep or remove heavy surface dirt first
to expedite the ozone cleaning process. Time
