Prepare the water for bathing
Water is an unstable and constantly changing element, especially in a swimming pool.
Physical and chemical water treatment is therefore essential to ensure that the water remains healthy, clear, balanced, disinfected, and antibacterial.
The range of water treatment products allows pool owners to tailor their equipment to their specific needs, from reducing maintenance requirements to enhancing bathing comfort, connectivity, or environmentally friendly solutions.
For optimal disinfection against pathogens (bacteria, viruses, fungi, etc.), you can combine UV treatment with chlorine treatment. This combination provides a broader spectrum of effectiveness, ensuring thorough disinfection of the pool water.
How does electrolysis work?
The principle of salt electrolysis is simple. Pool water is slightly salty (2 to 4 g/l, or 9 to 18 times less salty than seawater). Through the electrolysis reaction in the system’s cell, chloride ions from the salt dissolved in the water are converted into gaseous chlorine, a powerful disinfectant that immediately dissolves in the water.
The resulting active chlorine (HOCl) destroys microorganisms in the cell and maintains an appropriate level of free chlorine in the pool. Active chlorine is consumed through its reaction with organic matter and under the effect of UV rays from sunlight. The cell continuously regenerates it without any action required from the user.
The electrolysis unit must not be used to prepare the pool before the start of the season, but rather to maintain water quality during use. Before starting to use the unit, it is important to check and adjust the chemical composition of the water. Before use, the pool must be thoroughly cleaned of sediment, floating and suspended particles, algae, microorganisms, etc.
The chemical composition of the pool water must be within the following limits:
pH value: 7.2 to 7.4
Free chlorine: 0.5 to 2 mg/l
Total alkalinity: 8 to 15 g/l
Hardness: 10 to 30 g/l
Cyanuric acid: < 30 g/l
Salinity: 4 g/l
Metals: 0 mg/l
The sensors are installed immediately after the filter, while the electrolysis cell and dosing connections should be installed as the final components in the filtration system. During installation, the direction of water flow, the position (inclination/horizontal alignment) of the cell, and the minimum required length of piping on which the devices are installed must be respected.
The cell is installed using a bypass with valves to allow the flow to be adjusted and the pool to remain operational in case the cell needs to be removed. It is recommended to install a check valve downstream of the unit to prevent water from circulating in the opposite direction when the circulation pump is switched off. Open containers of dosing chemicals must not be stored in the equipment room.
Easy to install and use, saltwater chlorinators provide complete water treatment with reduced maintenance.
