As serious environment pollution
is being increased with rapid increase of
air pollutants discharging due to rapid
industrialization, the necessities for securing
public health and living space are being
raised. Ministry of Environment has enhanced
offensive odor related enforcement regulation
that has the greatest parts of civil appeal
in Air Preservation Regulations in order
to protect public health, and they are strictly
instructing and controlling offensive odor
generating companies.
Since offensive
odor, one of air pollution, is a pollution
that directly cause damages to sensibility
of human beings not like other pollutions,
such as water, noise, dirt and others, offensive
odor generating industry is expected to
be unable to perform their business at all
in our regional conditions, which are narrow
territory and densely populated region,
if there is no strict prior preventions.
Offensive odor
removing methods used until now are fundamental
offensive odor reduction technology, heat
incineration method, adsorption method using
active carbon, absorption method using spraying
tower and ventury scrubber, freezing contention
method, biophysical treatment and spraying
masking agent. These are used alone or together
with others, but they are not providing
satisfactory deodorization effect and being
operationally effective due to high operation
expense for recycling absorption agent and
purifying waste water.

Deodorization
water of Kyungwon generated by decomposing
water electrically with using catalyst is
harmless to human body and it is functional
water returning to natural water after use.
Offensive odor technology spraying deodorization
water may be called as a revolutionary technology
breaking from existing methods.
Deodorization
water of Kyungwon is generated by deodorization
water generator installed at field. Strong
oxide capacity in super oxide (O2-), hydrogen
peroxide (H2O2), ozone (O3) and hypochlorous
acidlorous acid contained in deodorization
water removes 80~90% of offensive odor creating
materials like ammonia, hydrogen sulfide,
trimehylamine and methyl mercaptan.
Since Kyungwon’s
deodorization water generator is cheap and
has simple installation method, its installation
expense is only 1/4 of existing spray tower
type absorption apparatus, which gives great
advantages in operational expense and efficient
deodorization removal..

-
pH(Hydrogen Ion Concentration) 2.7 or lower
- ORP(Oxidation Reduction Potential) 1,100mV
or higher
- Since Kyungwon’s deodorization water has
low pH and high ORP (Oxidation Reduction
Potential), it has high oxidation capacity.
Moreover, its containing ozone (O3), hydrogen
peroxide (H2O2), super oxide nonion (O2-)
and hydroxyl radical (OH) provides immediate
oxidation decomposition over hydrogen sulfide
(H2S), ammonia gas (NH3), trimehylamine
[(CH3)3N] and acetaldehyde, which are origins
of offensive odor, and neutralizes offensive
odor.

Tap
water and underground water contain
not only H2O, but also molecular materials,
such as O2, Co2, CaCo3 and others,
and non-ion, such as C1- and HCo3.
These materials are converted into
new material deodorization water after
going through energy and catalyst
reaction inside Kyungwon’s deodorization
water generator |

Since functional deodorization water
performs deodorization reaction after
being sprayed as many
small sprays returns to general water
and vaporized
naturally, there is no
possibility of secondary pollution.
Specially, because
offensive odor particles
move to various directions according
to movement of
air, sprayed small
functional deodorization waters move
together with
offensive odor particles
while performing deodorization reaction.
- Harmlessness test over human body
(Korea Research
Institute of Chemical Test: 97. 2
)
* Immediate oral test: Oral test result
from mouse came out to be harmless
(Max test 5,000mg
/kg).
* Eye irritation test: Conducted by
National Institute for Safety and
Health.
This test is performed
by inserting drops into eyes of rabbit.
The result came
out to be harmlessness
with causing no irritation.
- Also has sterilization capacity
