Salt electrolysis - an elegant way to disinfect pool water

The process of electrolysis is the separation of a chemical compound using electrical energy. The electrolysis process is carried out, with few exceptions, only in an aqueous environment. There is enough water in the pool, so an electrolysis system can be installed quite easily in the pool filtration.

What happens when water is subjected to electrolysis? Water is broken down into its components - hydrogen and oxygen. They are released in the form of gases.

When salt is dissolved in water, it is subjected to electrolysis instead of water, because the components of the salt (ions) react more easily.

This is exactly what salt electrolysis is. The salt used is the familiar table salt, sodium chloride. Electrolysis separates sodium chloride into sodium and chlorine. The chlorine thus produced reacts with water and hypochlorous acid and hydrochloric acid are formed. Hypochlorous acid serves entirely to disinfect the water in the pool. The hydrochloric acid remaining as a by-product reacts with sodium in the water and sodium chloride is formed again. This creates a cycle in which the electrolyzed sodium chloride is formed again and again.

Hypochlorous acid or the so-called "free chlorine" are ideal for ensuring impeccable disinfection of the pool water. Their effectiveness depends solely on the PH level (acidity) in the water. The acidity should be between 7 - 7.4.

What does the salt electrolysis system consist of?

The system is made up of a body in which the electrodes are located and where the electrolysis process takes place and a control panel, which in the simplest version provides a constant voltage (7 - 10 V).

The electrodes are constantly in the water and are made of titanium. When looking for a salt electrolysis system, it is very important that the electrodes are self-cleaning. In very calcareous water, there is a possibility that a layer of limescale will form on one of the electrodes, which disrupts the operation and shortens the life of the system. Self-cleaning electrodes deal with limescale deposits themselves by periodically changing their poles.

The salt electrolysis systems we offer have self-cleaning electrodes.

The salt electrolysis system has a flow sensor that monitors whether there is enough water pressure. If the pressure drops, the system stops working.

The display also shows whether the amount of salt is sufficient and if more needs to be added.

Advantages of salt electrolysis:

• Water disinfection is simplified
• There is no need to store large quantities of water disinfectants
• The use of water maintenance chemicals is minimized
• If you are absent for a long time, your water disinfection is guaranteed, because salt electrolysis works autonomously.
