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
No DBPs are formed.


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.
