Application of
Ozone in Water treatment for Swimming pools
Anybody entering a swimming pool contaminates the water
either from secretion or just from washing off.
Typical contaminated are
ü
Sweat
ü
skin flaks
ü
mucous
ü
hair ointments
ü
urine
In addition there are contaminants and organisms from
the environment of the swimming pools such as dust algae and
microorganisms therefore the pool water has to be constantly filtered
and disinfected.
Key Benefits of using
OZONE
in Swimming Pools / Spa Baths:-
»
Bacteria kill rate is up to three thousand times faster.
»
50% stronger oxidizer than chlorine.
»
Reduces traditional chemical use between 60% - 90%
.
»
Reduce handling and storage of unsafe chemicals.
»
Reduce constant purchasing of harmful chemicals.
»
Eliminate red, irritated eyes and dry, itchy skin.
»
Eliminate costly replacement of faded swimwear.
»
Remove unpleasant chlorine / chloramine odours.
» No
adverse health or environmental effects.
»
Improvement of the filter and coagulant capacities. This leads to a
reduction of coagulant use and less backwashing of the filter is
required.
»
Water consumption can be decreased, because of an increase in water
quality.
Advantage
of using Ozone v/s Chlorine :-
Some
of the advantages and disadvantages of ozone and chlorine used for
swimming pool water purification are:
●
Chlorine
is not only highly toxic, it is a poisonous gas
● Although ozone is rated as toxic at the 1.0 mg/1 level by the United
States government, no one has ever been known to have died as a result
of inhaling it. Ozone has a very pungent odor, noticeable at
the 0.01mg/1 level; is highly irritating at elevated levels; tends to
dry out the skin and mucous membrane and can cause temporary throat
discomfort.
● Chlorine is stored in high pressure containers on the premises and
can be dangerous. A broken chlorine line could cause serious problems.
● Ozone is generated on the premises (not stored)
● Chlorine, when mixed with urine and perspiration, will form
chloramines that will cause eye irritation and are toxic to aquatic
life.
● The cost of chlorine is constantly increasing and has become quite
expensive. Ozone, on the contrary, is becoming less expensive due to the
increase in efficiency and lower energy consumption. The overall cost of
using ozone instead of chlorine will be less costly to the pool owner.
● Ozone is the most active oxidizing agent that can be used with
safety. It is sometimes called “activated oxygen”.
● Tests have proven that ozone is from 600 to 3000 times more active in
the destruction of bacteria and viruses than chlorine in the same
concentration. Escherichia Coliform (E. coli) is killed within 5 seconds
by ozone at a concentration of 1 mg/1, whereas 15,000 seconds for the
same results using chlorine at the same concentration.
● Ozone is effective against mustiness, mildew, fungus and can be used
to eliminate the “locker room” odor in dressing rooms.
● Due to the flocculation process and the ozonation process, the water
in an ozonated pool is very clear. A sky blue color is imparted in the
pool water.
● Chlorine is more effective against algae growth. Outdoor pools using
ozone have a problem with algae bloom, under high temperature
conditions, that can be eliminated bu chlorine “ shock treatment’ of 5
to 10 mg /1, when needed.
● Chlorine needs pH control (7.0 to 7.4 pH) for reliable results. Ozone
does not not require pH control but some of the other chemicals used may
require such control.
● Ozone is an excellent deodorizing agent for many substances, such as
putrefactions, hydrogen sulfide, urine, smoke, cooking, paints, etc.
● Ozonated pools do not have the “bath tub ring” that is caused by skin
oils, grease, ointments, hair dressing and cosmetics used by the
swimmers
● Ozone is used in therapeutic pools and baths for the treatment of
skin infection and burns.
