e-clear vs ultraviolet light (UV)
How does it sanitize the water?
| e-clear |
UV |
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.
|
Sanitizes within a sealed chamber using ultra
violet light rays.
Germicidal UV lamps emit light rays (254nm)
that destroys up to 99.9% of water borne pathogens
by disrupting their DNA.
Does not produce a sanitizing residual in the water with sanitation occuring only in the UV chamber. Therefore UV systems require a free chlorine residual of at least 1ppm.
|
What sanitizing molecules/oxidizers
are produced?
| e-clear |
UV |
Within a sealed chamber, the powerful oxidizers
OH-, O1-, H2O2 and O2 are generated via electrolysis from the
water (H2O) molecule itself.
Dissolved O2 remains in the water and is combined with
copper ions to provide a long-lasting, stable
and healthy sanitizing residual. .
|
None. Requires an oxidizer such as chlorine.
|
Is it 100% chlorine free?
| e-clear |
UV |
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.
Since no oxidizers are produced and UV does not provide a sanitizing residual in the pool, UV requires a min free chlorine residual of 1ppm or can be combined with e-clear to provide a sanitizing residual.
|
Is the sanitation harmful to the
swimmer?
| e-clear |
UV |
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.
|
No.
Sanitation occurs in a sealed chamber away
from the swimmer.
However, since UV is combined with chlorine, harmful byproducts are still produced in the swimming pool.
|
Does it form disinfection
byproducts (DBPs)?
|
e-clear |
UV |
No chloramine gas or Trihalomethanes are are formed.
Even if combined with a small residual of chlorine oxidation breakpoint occurs via the e-clear system thus preventing the formation of harmful DBPs.
|
Yes, because UV is combined with chlorine both chloramine gas and Trihalomethanes (THMs) are formed.
UV is often installed to reduce the levels of chloramine gas (combined chlorine), but it does not reduce THM levels.
|
Does it give off odours/gasses?
|
e-clear |
UV |
|
No odours and no gasses are
generated
|
Yes, since UV needs to be combined with chlorine, chloramine gas is produced. UV is effective in breaking down chloramine gas. |
Is it eco-friendly
and water wise?
| e-clear |
UV |
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.
|
No.
UV still requires a 1ppm residual of free chlorine.
When combined with e-clear, swimming
pools can be back washed directly to irrigation.
|
Does your pool pump
have to run 24/7?
| e-clear |
UV |
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 UV does not provide
a sanitizing residual, pumps have to run 24/7. |
Is the sanitation
pH dependent?
| e-clear |
UV |
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, since UV is combined with a chlorine residual an optimum pH of 7.2-7.6 has to be maintained.
|
How corrosive is it?
| e-clear |
UV |
Not corrosive.
Oxygen converts calcium in the water to a
soft bicarbonate form. This results in water that is soft and gentle.
|
Corrosive when combined with chlorine.
