Dissolved Ozone Monitor/Controller

By far the most accurate way to measure and 
control the ozone in the water, a dissolved ozone 
monitor/controller may be used to ensure that the 
water is completely charged before starting the tim-
ing of the  cycle, as well as providing a continuous 
monitor for observation.  In addition, it can be used 
to control the ozone system so that the tank of water 
can be main tained continuously and stays charged 
at the exact amount determined by the adjustable 
set-point; it will cycle the ozone system on and off 
as needed to maintain the set-point.

Indigo Blue Ampules with Colorimeter (Hach Ac-
cuVac 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

.  There-

fore, 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 dis charge 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)

4E-1a. 

Refer to the 

Ozone Tank Charging Guide-

lines

.  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 ap prox i mate ly 3 PPM.  The time necessary 
to ac com plish this is de pen dent on the volume of 
water in the tank.  Once the water is charged with 3 
PPM ozone, CIP op er a tion 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 pref er-
 enc es vary, but 30 minutes is the rec om mend ed 
optimum.

4E-1b. General Tank Sanitation - 

See page 3, 

drawing 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 wa-
ter in the 

ozone charge tank,

 and charge

 

the water 

to ap prox i mate ly 

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 di rect ed on fl oors, drains, walls, 
wettable equipment, external or internal tanks, clean 
rooms, etc. (If the ozone spray is being applied in a 
very small, en closed, poorly ventilated area, it may 
be nec es sary to wear a standard ventilator to avoid 
the inhalation of ozone gas.  Breathing ex po sure 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 
nec es sary to attain san i ta tion de pends on the 
amount of debris found in the area to be cleaned.  
Sweep or remove heavy surface dirt fi rst to ex pe dite 
the ozone clean ing process.  Time es ti mates for 
proper san i ta tion are diffi cult to predict due to the 
variety of areas, surface materials and contami-
nants.  How ev er, experience and studies support 
that 

30 sec to 2 minutes

 of spray time is generally 

all that is nec es sary for complete sanitation. DEL 
rec om mends that end-users utilize their own san i -
ta tion effi cacy testing protocol to de ter mine nec-
 es sary spray time.
