e-clear vs salt chlorination


How does it sanitize the water?

e-clear
salt

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.

E-clear does not require salt.

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.

Salt chlorinators produce chlorine gas via electrolyses of salt (NaCl).

Chlorine gas is converted to Sodium Hypochlorite (liquid chlorine/bleach) in the swimming pool water.

The process of generating chlorine also produces sodium hydroxide, NaOH (sodium hydroxide or caustic soda) in the water.

What sanitizing molecules/oxidizers are produced?

e-clear
salt

Within a sealed chamber, the natural oxidizers OH-, O1-, H2O2 and O2 are generated via electrolysis from the water (H2O) molecule itself.

Saturation levels of dissolved oxygen (DO) in the pool is combined with a trace levels of copper ions to provide a long-lasting, stable and healthy sanitizing and algaecidal residual.

For some applications also combines UV.

In water, Sodium Hypochlorite forms the oxidizer Hypochlorous Acid (HOCL).

 

Is it 100% chlorine free?

e-clear
salt

Yes.

O2 and copper ions provide an effective and long-lasting sanitizing residual in the swimming pool.

e-clear does not require any chlorine.

No.

A saltwater pool is not chlorine-free; it simply utilizes a chlorine generator instead of direct addition of chlorine.

How powerful are the oxidizers, i.e. What are their respective Oxidation Reduction Potential (ORP) values?

e-clear
salt

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):

Sodium Hypochlorite (0.69), HOCL (1.1)

How much oxidation is produced?

e-clear
salt
Very high and constant oxidation output.

Entry Level Patented Stack anode design with autocatalytic oxidation generates ~40,000g oxidizers per 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.

Some chlorinators do not generate enough chlorine and requires addition of chlorine manually.

 

Are the oxidizers harmful to the swimmer?

e-clear
salt

No, e-clear is 100% non-toxic.

Highly reactive e-clear oxidizers are produced in a sealed chamber, away from the swimmer and not in the swimming pool itself.

In the swimming pool water, 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, with salt water pools you are still swimming in chlorine, which 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.

Although salt makes the water feel softer, HOCL is harmful and attacks the skin, hair and eyes of swimmers.

Does it form disinfection byproducts (DBPs)?

e-clear
salt
No DBPs are formed.


Yes, chlorine generated from salt binds organic matter in water to form harmful organo-chlorines or DBPs such as the Trihalomethanes (THMs).

The predominant THM is Bromoform (Confirmed carcinogen in animals).

Bromoform is not as volatile as chloroform and has been shown to accumulate to very high levels in the pool. Bromoform is absorbed mainly through the skin and inhalation.

Recent studies have shown Bromoform is highly genotoxic and readily absorbed through the skin.

Does it give off odours/gasses?

e-clear
salt
No chloramine gas is produced. Therefore no 'chlorine' odours and no toxic gasses are generated


Yes, since salt chlorinators generate chlorine, salt pools generate chloramine gas producing a strong 'chlorine'. Chloramine gas 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
salt

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.

Salt chlorinators have been banned in a number of states in the USA and areas of Australia due to harmful salinification of natural water ways. Urban salinification is becoming a growing environmental concern.

Salt chlorination also produces greenhouse gasses and harmful POPs including Bromoform.

Not water wise. Due to high salt levels and pollutants salt pools can not be back washed directly to irrigation.

Salt chlorinators have a high electrical consumption.

How efficient is the sanitation in heated water?

e-clear
salt

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.

Since salt chlorination generate chlorine, salt chlorination does not sanitize efficiently at temperatures exceeding 32oC,

Does it require stabilizing chemicals?

e-clear
salt

No, e-clear sanitation is not affected by sunlight (UV) and requires no stabilizing chemicals.

Yes, since salt chlorinators produce chlorine and chlorine is destroyed by sunlight (UV), salt pools require stabilizing chemicals such as cyanuric acid.

Is the sanitation pH dependent?

e-clear
salt

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.

When the HOCL is used up what is left is NaOH (sodium hydroxide/caustic soda). This causes the pH of the pool to rise. Acid consumption is salt pools are therefore higher than that of chlorine pools.

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
salt

Not corrosive.

Oxygen converts calcium in the water to a soft bicarbonate form.

This results in water that is soft and gentle.

Salt and chlorine pools both produce HOCL oxidizers which are very corrosive.

Since salt acts as an electrolyte in water this increases corrosion via electrochemical galvanic corrosion.
