Why Air purification and Odour
Control is necessary?
Today's Hotels, its critical areas like
butchery, kitchen, food preparation area, restaurants, bars and similar
areas are centrally air conditioned and create its own form of indoor air
pollution or commonly known as "sick building syndrome"
due to nearly-air tight construction and absence of enough fresh air from
Some foul odour can be literally built-in with organic products, smoke,
meat, fishes and left over food products. These materials often contain high
Volatile Organic Carbon (VOC) content which can cause rashes and nausea. The
unpleasant smell is not only bad enough, but allergic reaction can be a more
What is required?
What is needed is a way to quickly and
economically eliminate the foul smell generated by meat products different
biological sources, mustiness from mold and mildew, stale tobacco odour and
other unpleasant odors.
What is the solution?
Ozone treatment is a proven & a viable
solution to purify & de-odorize air in hotels, butcheries, restaurants,
bars, health clubs, offices, guest rooms and other rooms. Unlike
air-freshness or chemicals, "Ozone the nature's most powerful purifying
agent" does not mask the odour like deodorization sprays, but actually
eliminates them through natural oxidation. It has been shown in various
tests that alertness and efficiency of an individual increase appreciably in
the environment of controlled Ozone.
How Ozone can be used for Air
Purification & Odour Control?
Ozone is a very strong oxidizer and has
powerful purifying property. It has a strong potential to remove organic
odour by oxidizing odour-causing molecules. A very small and safe
concentration of Ozone can purify and de-odorize air much better than any
de-odorizing spray. Today Ozone is considered by most to be the best
available and advanced technology and a much better alternative than using
How do we estimate quantity of
Ozone (gm/hr) for a specific area?
Ozone required to be dosed in a specific area
e.g. a hotel room ,butchery, restaurant, bar or a basement office depends
upon the size (volume) of the room, position of air handling system, level &
nature of Odour extent of VOC, temperature of the area and presence of
Ozone quantity is correctly estimated by taking various parameters into
consideration using a computer programme. However for a rough estimation, as
a thumb rule, for an area of less odour and clean e.g. hotel rooms, offices,
conference rooms, 1 gm/hr Ozone is required for 6,000 Cu.ft. space, while
for area of higher bacterial contamination and foul smell as butchery,
basement rooms, moist stinking areas, 1 gm/hr Ozone is need for 3,000 Cu.ft.
After dosing the estimated Ozone, in case the concentration of Ozone in
environment is higher than 0.05 ppm (where persons are present) the amount
of Ozone being dosed should be reduced.
What is the Concentration of
Ozone, required to be maintained in the Area?
A very small Ozone concentration of 0.02 to
0.08 PPM is adequate for achieving air purification & deodorization,
however on this concentration little more time is needed to get the desired
results. Actual concentration required to be maintained at a place depends
upon the presence of persons, type and nature of odour, the criticality of
the area, duration required to purify and extent of foul smell. If no body
is present in the room higher concentrations can be used for faster results.
What is the Limit of Ozone
Concentration where persons are present?
Ozone Concentration should not exceed more than
0.1 PPM where persons are present, for eight hours or more per work day, and
no person be exposed to a ceiling concentration of Ozone in excess of 0.6
mg/m³ (0.3 PPM by volume) for more than ten minutes. This limit is set
as per OSHA standards. As per ASHERE 0.05 PPM is the limit of Ozone
concentration where persons are present.
What is a Ozone Purification &
De-odourisation System & How it works?
Controlled quantity of Ozone is diffused into
- Using individual Ozone Generators of small capacity e.g. 0.5 or 0.75
- Through a network of diffusers into the affected area, The diffusers
are connected to a Central Ozonator.
- If an Air Handling System exists, it is better to use Duct mounted
Ozonators in the duct emerging out from AHU. The injected Ozone gets
mixed with the total air stream and provides a uniform distribution and
Ozone Air purification is a continuous and safe process.
Monitoring and Control of Ozone
Concentration of Ozone in air is monitored by
Ozone Monitors using semi-conductors based sensors manufactured by CREATIVE
OZ-AIR (I) PVT. LTD". For Automatic regulation of Ozone concentrationa
feed back loop can be used. The monitoring system is equipped with high &
low level alarm, which can be used for providing warnings or control
Uses of Ozone increasing the shelf
life of the food products
In most of the cases the stalling of any Food
and meat, fishes, etc. are due to the growth of Bacteria and viruses, if we
reduce the same with the help of some means we can increases its shelf life.
But it is also equally important that the additive should be such which does
not leave any residue in the final product and thus we are only left with
one chemical that is OZONE.. Ozone is a Triatomic state of oxygen and after
disinfection and sterilization it converts back to Oxygen without leaving
any residue. In your case we can use Ozone in following ways:
- Environmental Air Sterilization System The air inside the
packing and processing hall can be made disinfected with the help of
diffusing Ozone into the Packing or processing hall we can make area
completely sterilized without use of any fumigants or chemicals.
- Director Treatment of Product Ozone can be brought in direct
contact with the product for reducing bacterial count. The Ozone contact
and concentration is controlled as per the automatic regulation.
However, we can suggest you an appropriate system only after studying
the situation at site.
- The water used for washing of fruits and vegetables, meat products,
fisheries, prawn and other products, cleaning the places adding to
product and mixing into the process can be disinfected Ozone. We have
water treatment sterilization and equipment for production of
disinfected pure water for food processing applications.
- With the help of Ozonated Showers the containers and machines can be
