Diving into a saltwater pool is a rare occurrence. But saltwater pools have gained popularity in recent years as an alternative to traditional pools. Their operation is based on the electrolysis process, which converts salt into chlorine to disinfect the water. This type of pool has advantages and disadvantages that should be considered. Among the advantages are economic savings and simplified maintenance, while the main disadvantages are the initial cost and the corrosiveness of salt water.
Operation of a saltwater swimming pool
Saltwater pools operate by means of an electrolysis system that transforms dissolved salt into chlorine, thus offering a more ecological and efficient alternative to keep the water clean and treated.
Electrolysis process
The electrolysis process is essential in saltwater pools. This method uses an electrical generator that breaks down salt molecules (sodium chloride) into their basic components. By applying an electric current, the sodium and chlorine atoms are separated.
The chlorine released is responsible for disinfecting the water, eliminating bacteria, viruses and other germs. This process is carried out continuously, which makes it possible to maintain an adequate level of disinfectant in the water. This avoids the need to add chemical chlorine regularly, which can be harmful to the skin and eyes of bathers.
Saline chlorination
Salt chlorination is the method by which the salinization of the water in these pools is ensured. Through the electrolysis mechanism, salt is transformed into chlorine, which sets in motion a natural and sustainable cycle.
This type of chlorination provides a more consistent level of chlorine than traditional methods. The continuity of chlorine production ensures that the water remains clean and safe for bathing at all times. By not relying on external chemicals, exposure to substances that can cause irritation is reduced.
