e-clear vs chlorine
How does it sanitize the water?
|
e-clear
|
chlorine
|
E-clear produces powerful natural oxidizers through an advanced electrolysis of water (H2O) technology.
The e-clear natural oxidation technology is combined with a trace amount of copper ionization to provide 100% protection against waterborne pathogens.
Saturated levels of Oxygen and a small copper ion residual in the pool ensures there is an effective sanitizing residual in the pool at all times, even when the pumps are not running. This feature enables e-clear pools to operate 100% chlorine free.
|
Chemical oxidation. Usually
added as chlorine gas or as calcium hypochlorite.
|
What sanitizing molecules/oxidizers
are produced?
|
e-clear
|
chlorine
|
Within a sealed chamber, the natural oxidizers
OH-, O1-, H2O2 and O2 are generated from the
water (H2O) molecule through an advanced electrolysis process.
Saturation levels of dissolved O2 and
copper ions provide a long-lasting, stable
and healthy sanitizing residual in the pool.
For some applications also combines UV.
|
In water, chlorine gas, Sodium- and Calcium
Hypochlorite forms the oxidizer Hypochlorous
Acid (HOCL).
|
How powerful are the oxidizers,
i.e. What are their respective Oxidation
Reduction Potential (ORP) values?
|
e-clear
|
chlorine
|
Powerful natural oxidizers with High ORP Values
(click here
for ORP Table):
OH- (2.05), O1- (1.78), H2O2 (Liquid Oxygen
- 1.3) and O2 (0.94)
|
Average ORP Values (click here
for ORP Table):
HOCL (1.1), Chlorine Gas (1.0), Sodium Hypochlorite
(bleach) (0.69) and Bromine (0.57)
|
How much oxidation
is produced?
|
e-clear
|
chlorine
|
Very high and constant oxidation
output.
Small Stack O2 anodes generates ~40,000g oxidation/hr.
Commercial Multiple Stack anode systems are
custom made to match bather load.
|
Highly variable depending on bather load, ie
chlorine reacting with organic matter reduces
available HOCL levels.
Minimum chlorine residual of 1ppm required with most commercial pools maintained at 2ppm free chlorine.
|
Are the oxidizers
harmful to the swimmer?
| e-clear |
chlorine |
No, e-clear is 100% non-toxic. It relies mainly on a natural oxygen technology and produces only a trace amount of copper ions.
Copper levels are carefully regulated to ensure levels remain within drinking water standards.
E-clear's powerful oxidizers are produced
in a sealed chamber away from the swimmer.
In the swimming pool water, dissolved Oxygen and Ionization
provide water that is sanitized yet healthy
and therapeutic, soft and gentle.
No corrosion, red eyes, dried out hair or skin.
|
Yes, chlorine is toxic and harmful to the swimmer.
HOCL, an aggressive and corrosive oxidizer,
is produced in the swimming pool itself.
HOCL is absorbed through the skin and produces
harmful reactive O1- radicals within living
cells.
HOCL is harmful and attacks the skin, hair
and eyes of swimmers, leaving eyes red and skin
and hair dried out and brittle.
|
Does it form disinfection
byproducts (DBPs)?
|
e-clear
|
chlorine
|
| |
Yes, a highly reactive gas, chlorine rapidly
binds organic matter in water to form harmful
organo-chlorines or DBPs such as the Trihalomethanes
(THMs) and chloramine gas.
The predominant THM is Chloroform (Class 2A
carcinogen) and Bromoform in salt pools.
Chloroform is volatile and absorbed mainly
through inhalation and the skin.
THMs in water is linked to increased risk of
bladder and other cancers and birth defects.
|
Does it give off odours/gasses?
|
e-clear
|
chlorine
|
No odours and no gasses are
generated
|
Yes, generates strong odour from Chloramine
gas, a toxic gas that is produced when chlorine
binds sweat, urine and organic matter.
Chloramines are highly aggressive and toxic
when inhaled and significantly increases the
risk of developing bronchiolitis, asthma and
allergies.
|
Is it eco-friendly
and water wise?
|
e-clear
|
chlorine
|
Yes.
Does not generate any persistant organic pollutants
(POPs)/ DBPs and no greenhouse gas emissions.
Water is free from harmful chemicals and pollutants
so swimming pools can be back washed directly
to irrigation.
Energy and Water efficient.
|
Not ECO-Friendly.
Chlorine is a greenhouse gas.
DBP gases formed by chlorine and organic matter,
such as chloroform is a greenhouse gas.
Also generates DBPs that are POPs and harmful
to the environment.
Not water wise. Due to toxicity and pollutants
can not back wash directly to irrigation.
|
How efficient is the
sanitation in heated water?
|
e-clear
|
chlorine
|
Very efficient.
Due to the high oxidation output e-clear is
highly efficient in heated water, even at temperatures
exceeding 32oC.
Copper ionization, which is unaffected by heat,
provides a lasting residual even in warm water.
|
Not efficient.
Chlorine does not sanitize efficiently at temperatures
exceeding 32oC, with increased levels of chlorine
required in heated water.
|
Does it require stabilizing
chemicals?
|
e-clear
|
chlorine
|
No, e-clear sanitation is not affected by sunlight
(UV) and requires no stabilizing chemicals.
|
Yes, chlorine is destroyed by
sunlight (UV) and requires stabilizing chemicals
such as cyanuric acid. |
Is the sanitation
pH dependent?
|
e-clear
|
chlorine
|
Yes, pH must be managed and maintained at neutral
pH, ie pH6.8 - 7.2.
pH is very stable due to high levels of Dissolved
Oxygen and absence of chemicals in the water,
so e-clear pools require ~10x less HCL than
chlorine pools.
Oxidation efficiency decreases above pH7.2.
Acid management is required to maintain pH below
7.2. Pool acid, a food grade HCL or citric acid
is recommended. Since the pH reaction goes to
completion immediately water remains chemical
free.
No alkaline management required. Even if pH
drops to 6.8 water remains soft, gentle and
non-corrosive since water is chemical free.
|
Yes.
pH sensitive with optimal range between pH
7.2 and 7.6.
Requires acid and alkaline management.
Above pH7.6 oxidation efficiency decreases
rapidly due to reduction in HOCL oxidizer levels.
Below pH 7.2 water becomes highly aggressive,
corrosive and burning, due to increase in HOCL
levels.
|
How corrosive is it?
| e-clear |
chlorine |
Not corrosive.
e-clear produces oxygen in the water. Oxygen
converts calcium in the water to a bicarbonate
form which softens the water.
|
Chlorine pools produce HOCL oxidizers in the
water which are very corrosive.
