What is the advantage of salt electrolysis in a swimming pool?

Advantage of salt electrolysis

The advantage of salt electrolysis is that the salt electrode automatically produces chlorine that disinfects your swimming pool water. This means that you do not have to store dangerous chemical products and do not have to manually add chlorine to the pool.

How does salt electrolysis work

Electrolysis in swimming pool water is a splitting of NaCl. You can find the formula below: NaCl --> HClO (hypochlorite) is the oxidizer that disinfects your water.

The benefits of salt water disinfection

• The advantage of salt electrolysis is that it reduces the gcheapest pool water treatment available is. This system only requires an annual addition of 100 to 150 kg of salt (for a swimming pool of 50m³ – 200 kg at start-up). The adjustment of the pH value is done manually. With a salt electrolysis, the pH value will be less influenced than with all other pool water treatment techniques.
• A salt electrolysis is broken more pleasant to swim in and softer to the touch. Due to the salt concentration in the swimming pool water (4 g/l), the skin will have less tendency to dry out as with conventional use of chlorine tablets or liquid chlorine. This is because our body fluid also contains salts (9 g/l) and the swimming pool water approaches this salt concentration.
• With salt electrolysis prevent the formation of red eyes and skin irritation. Chlorine reacts with dirt caused by the swimmer (perspiration, urine, suntan lotion, …) and forms chloramines. These chloramines cause skin and eye irritation. The chloramines are destroyed with the salt electrolysis in the electrolysis cell during the operation of the filter installation and the Less salt electrolysis.

Hydrolysis in combination with salt electrolysis

Newer systems nowadays combine hydrolysis (splitting of H2O) with salt electrolysis. These pool water treatment systems then work with a much lower amount of salt in the pool water (<1.5g/m³).

The Aquarite LS systems are often installed in private swimming pools, with now the successor the Aquarite+. But the new innovation has to be the Oxilife van Sugar Valley! Discover the product below.

The best alternative to the Zodiac Nature 2

The ideal replacement for the Zodiac Nature 2 (which are no longer available since 2019) is an electrolysis with low salt concentration. These systems do not cause irritation, do not sting the eyes, do not smell of chlorine, do not dry out the skin, are not corrosive to your swimming pool techniques, etc…
