machine) can be detected. While the machine produces a range of different oxygen
radicals into the water, ozone is the one easiest to detect. Ozone will start to decay
back into oxygen immediately after the device is turned off. In 20 °C degree water,
the half-life of ozone is 20 minutes.
•
If the water is being treated for it to be used as drinking water, wait until the ozone
has completely disappeared from the water. This takes anywhere from five minutes
to one hour depending on water temperature, iron content and other factors. Water
can be consumed as soon as the smell of Ozone cannot be detected..
Comments
•
The EOD MEDI EORG generator works best in cold or cool water (less than 20 °C).
•
The EOD MEDI forms ROS and aqueous ozone. Generator does not work in water
with very low electrical conductivity. Therefore, the device should not be used with
e.g. ion exchanged battery water or water purified by reverse osmosis.
•
With the EOD MEDI it is not possible to “over ozonize” the water, but it is possible
that the ozonizing does not reach the desired level for the intended purpose. If this
happens, repeat the treatment of water with the EOD MEDI generator.
•
Correct operation of the device can be visibly observed as soon as the device is
switched on whilst submerged in clear water. Stream(s) of micro bubbles will start to
rise from the electrolysis plates.
•
The water is quickly filled with micro bubbles. When the device is turned off, the
micro bubbles immediately begin to dissolve into the water. The water is ready for
disinfection once most of the micro bubbles have dissolved (i.e. the water resumes a
clear appearance)
Examples and notes
•
For the preparation of sufficiently concentrated disinfectant in a water volume of
twenty (20) liters (at 20
°
C room temperature), let the device run un-interrupted for
twenty (20) minutes. In a water volume of forty (40) liters, the corresponding
operation time required is forty (40) minutes.
•
Continuous use of the EOD MEDI generator for longer than one hour (60 minutes) is
not recommended. In between uses, allow the EOD MEDI generator as well as the
current transformer time to cool down at least 10 minutes before re-use.
NOTE: In highly conductive waters (high TDS value) the device might become
noticeably warm
NOTE: In waters with low electrical conductivity (low TDS value) the reaction might
not start. By adding a trace amount of mineral water into the mix, the reaction should
start.
NOTE: Never add any chemicals or other additives (apart from mineral water) into the
water being treated. This may result into unpredicted chemical compounds
becoming airborne and EOD Europe accepts no liability of any harm to materials or
persons due to this.
