Swimming pool disinfection
All along,
the artificial pool disinfection has been using iodide and chloride,
as well as chlorine, poisoning frequent generators. Until the
twentieth century, the development of ozone technology, only the
ozone into the water treatment field, and has increasingly shown its
superiority, ozone is a world recognized green disinfectant, many of
the world's developed countries, large swimming pool and high-
standard swimming pool are using ozone disinfection, international
competition venues are also using ozone disinfection equipment.
Here we look at chlorine disinfection and ozone disinfection
advantages and disadvantages:
(A) chlorine disinfection
Conventional chlorination chlorine disinfectants (usually
chlorine), sodium hypochlorite, chlorine dioxide, chloramines,
bleach, bleach and chlorine tablets fine.
Chlorination advantages are:
1) bactericidal effect;
2) there is continuous disinfection capabilities.
Disadvantages are:
1) smell and eye and respiratory irritation;
2) on the pond structure, equipment and piping have a corrosive
effect; operations management requires high level, otherwise a
security incident;
3) Long-term exposure with water will make people's hair color
yellow, affect the appearance;
4) the most serious, almost accepted that oxidative chlorination
process produces chlorine derivatives may be carcinogenic, talking
about cancer, discoloration today, especially daunting. Should be
used with caution.
(Two) ozone disinfection
Ozone is a strong oxidant, a broad-spectrum, high efficiency,
rapid fungicide, which can quickly kill various bacteria pathogenic
to humans, viruses and bacteria, and a stronger bactericidal effect
of ozone dissolved in water, the water reached the ozone 0.3mg / L,
the role of one minute on Escherichia coli and Staphylococcus aureus
inactivation rate of 100%. For hepatitis B surface antigen,
hepatitis A virus antigen and other viruses have a very good role in
the killing.
The use of ozone for swimming pool water disinfection, can
achieve the following results:
A) Ozone and its secondary products (such as hydroxyl) has the
strongest bactericidal effect and inactivate the virus, which can
effectively guarantee the water quality and prevent the spread of
infectious diseases, and its sterilization faster than chlorine 600
to 3000 times, especially inactivation of the virus is very strong.
2) ozone can effectively decompose water humus, water, iron
oxide, manganese ions, decomposition tiny organisms in water scatter
light, thus greatly improving water clarity, so that the water
showing a beautiful blue.
3) adding chlorine preparations, PH value of water will
inevitably lead to a change, people feel discomfort, therefore,
requires the addition of an alkaline or acidic substances to be
neutralized. The ozone is a neutral substance, no such problems, can
play a role in stable PH value.
4) to ensure that large ozone season water quality traffic and
high temperature stability.
5) the use of ozone generators, can greatly reduce the
management and operation of water treatment processes difficulty,
while the ozone generator has a high safety, and chlorine
preparations in the transport, storage, use, have a certain degree
of risk.
6) Ozone decomposable organic matter in water and a micro
flocculation, which in normal traffic, the flocculant can not.
7) the use of ozone, can filtration rate increased by 1/3, the
recoil water consumption reduced by 50%, thus reducing operating
costs,
8) to reduce the consumption of chemical reagents 50% or more.
9) to eliminate the pungent odor of chlorine, to avoid the
traditional processing method produces pool rash, watery eyes, hair
damage and other symptoms.
10) can destroy organic compounds in water, improve water
physical properties and organoleptic, decolorization and
deodorization deodorizing effect, so that the water was blue,
without changing the nature of the water.
In summary It is obvious that ozone is a perfect
alternative to chlorine disinfection of swimming pool disinfection
methods, some domestic cities Pool managers have realized this, and
gradually transform the pool. Beijing mountain US-green water source
of the company's high concentration of ozone oxygen machines have
been widely used in the major pool and achieved good results.
