e-clear vs ozone (O3)
How does it sanitize the water?
| e-clear |
ozone |
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.
|
Ozone is produced electronically from Oxygen
(O2) using ozonators or UV ozone generators.
Ozone gas is a strong, yet unstable oxidizer.
Combined with chlorine/bromine to provide a
sanitizing residual.
|
What sanitizing molecules/oxidizers
are produced?
| e-clear |
ozone |
Within a sealed chamber, the powerful oxidizers
OH-, O1-, H2O2 and O2 are generated from the
water (H2O) molecule itself.
O2 remain in the water and is combined with
copper ions to provide a long-lasting, stable
and healthy sanitizing residual.
For some applications also combines UV.
|
A highly reactive oxidizer, ozone is produced
in the swimming pool water where it decays to
form OH- radicals.
|
Is it 100% chlorine free?
| e-clear |
ozone |
Yes, with a saturation level of dissolved O2 and a stable copper ion residual in the pool, e-clear provides an effective sanitizing and algaecidal activity without the need for chlorine.
|
No.
Ozone has a short half life in water (approx
20 min) and therefore requires a sanitizing
residual such as chlorine.
|
How powerful are the oxidizers,
i.e. What are their respective Oxidation
Reduction Potential (ORP) values?
| e-clear |
ozone |
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)
|
High ORP Value (click here
for ORP Table):
O3 (1.52)
|
How much oxidation
is produced?
| e-clear |
ozone |
Very high and constant oxidation
output.
Single pair small anodes generate ~3,500 g/h
oxidizers.
Entry Level Patented Stack anode design with
autocatalytic oxidation generates from ~40,000g/hr.
Commercial Multiple Stack anode systems are
custom made to generate 100kg+ oxidizers to
match bather load.
|
Oxidation output of domestic ozonators is extremely
low, ranging from 0.2g/hr to 8g/hr.
Commercial systems generate approx 100g/hr.
Very expensive industrial systems are required
to generate higher levels.
|
Are the oxidizers
harmful to the swimmer?
| e-clear |
ozone |
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, ozone is a powerful and harmful oxidizer
that is produced in the swimming pool itself.
Ozone is very harmful when inhaled and can
cause bronchial problems.
|
Does it form disinfection
byproducts (DBPs)?
| e-clear |
ozone |
|
|
Yes, ozone binds organic matter in water to form harmful DBPs, acetaldehydes.
When combined with chlorine and bromine it
forms highly toxic DBPs.
|
Does it give off odours/gasses?
| e-clear |
ozone |
No odours and no gasses are
generated
|
Yes.
Ozone gas has a pungent smell and is harmful
when inhaled.
|
Is it eco-friendly
and water wise?
| e-clear |
ozone |
Yes.
Does not generate any persistant organic pollutants
(POPs)/ DBPs and no greenhouse gas emissions.
Energy efficient.
Water wise, since water is free from harmful
chemicals and pollutants swimming pools can
be back washed directly to irrigation.
|
Not Eco-friendly.
Ozone is a greenhouse gas and pollutant at
ground level.
Ozonators have a high electrical consumption.
Water wise. With reduced chlorine levels swimming
pools can be back washed directly to irrigation.
|
Does your pool pump
have to run 24/7?
| e-clear |
ozone |
No, pumps run for normal 8-10 hours in summer.
e-clear sanitizes the pool even when the e-clear
system and pumps are switched off.
|
Yes,since ozone does not provide
a sanitizing residual, pumps have to run 24/7. |
Is the sanitation
pH dependent?
| e-clear |
ozone |
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.
Ozone rapidly decays above pH 7.6 and oxidation
efficiency decreases with increasing pH.
Acid management is required.
|
How corrosive is it?
| e-clear |
ozone |
Not corrosive.
Oxygen converts calcium in the water to a
soft bicarbonate form, resulting in water that
is soft and gentle.
|
Ozone is a strong oxidizer and corrosive.
