UV Mixing tower For Swimming Pool / UV-O3 Disinfection system
We use iodide, Chloride or liquid Chlorine for swimming pool
treatment for a long time. Till the development of ozone technology
of 20th century, have made ozone enter the field of water
treatment, and more and more show its superiority. But there are
still some problems in operation:
- Because thinking about the cost of ozone generator & mixing
reaction tower, many users do not choose it.
- It is few kind of Gas-liquid mixing device, and low mixing
efficiency, about 40-70% ozone can not be mixed in water. So for
better efficiency, the suppliers should increase ozone output which
will increase the cost.
- Hard to ensure the quality of mixing device, reaction tower and
other components if buy them separately.
For several years researching, now we use UV & Ozone together
for improving ozone dissolution ratio. UV-O3 Disinfection system
combined with ozone and ultraviolet.
- Theory evidence:
Scientists have discovered that added UV in ozone disinfection
system can stimulate activity of ozone, and catalyze ozone &
water molecules to create plenty of hydroxyl radical (OHˉ). OHˉ is
active material which was produced by reaction of ozone with water.
The oxidizing ability of OHˉ is 100 times higher than hypochlorite
The sterilization ability of OHˉ is 3000 times higher than
The sterilization ability with UV & Ozone is 1-2 times higher
than use ozone individual.
- UV-O3 Disinfection system used for pool water
- UV-O3 system has the strongest ability of sterilization and
inactivated virus, which can effectively prevent the spread of
infectious diseases. Experiment proof that inactivation of fecal
Escherichia coli requires only 5 seconds, if want to achieve the
same affection with the same concentration of chlorine required
15,000 seconds. Some of the pathogenic bacteria are resistant to
chlorine, such as virus, Amoebae, Cysts etc. But all of them can be
killed by OHˉ.
- UV-O3 system has strong oxidizing ability. It can prevent the
special odor compounds accumulated in swimming poor water,
including chlorinated organics what is reacted by Chlorine with
excretion, for example, mono chloro amine, dichloramine,
trichloramine, THM, chloriduria etc. Most of them are precursors of
THM. But ozone can constantly prevent generation of precursors in
swimming pool, to supply clear water, fresh air for swimmer, and
without stimulation to their eyelids and nose strip.
- UV-O3 system also can help sand filtration to removal of metallic
salts and organics. Because the organics will easily become
multi-polar compounds during oxidation process, and can combine
with a number of multivalent metallic cations (eg. Ca, Mg, Fe, Al
etc) into the complex compounds. And become micro-flocculate were
removed by sand filtration last.
3. System Structure
① Use booster pump, injector and reaction tower for ozone mixing in
water, then water return to pool. Because the irradiation of UV has
greatly increased generate of OHˉ. OHˉ speeds up the oxidation and
sterilization efficiency for water.+
② UV-O3 system, because it using UV, it not only have an excellent
effects of sterilization & oxidation under low ozone output
working condition, but also can avoid risk of high ozone
concentration in swimming pool (eg. >0.15 Mg/L). With using UV
for small size of reaction tower, there is no need to use activated
carbon for ozone destructor which can save much cost.
- UV-O3 can reduce the dosage of Chlorine. If the efficiency can
match with requirements of sterilization and oxidation, the amount
of Chlorine could be further decreased, combined Chlorine, free
Chlorine can be respective lower than 0.2 mg/L, 0.4 mg/L in water.
The Chloramines and THM have been substantially reduced to a
certain extent. It will be the important part for meet with the
requirements of environmental protection.
- In UV-O3 system, OHˉ has strong oxygenolysis ability for organic
pollutants. The production of OHˉ and its reaction with organic
pollutant only can be carried out under UV.
- Using UV-O3 system can save ≧40% cost than use ozone only.
