To enjoy a clean, healthy, and inviting pool, a water treatment system is necessary. The pool electrolyzer is the most suitable device because it is efficient, eco-friendly, economical, and requires little maintenance.
A pool electrolyzer is also called a salt electrolyzer because it requires the addition of salt to the pool water. It allows for automatic and perpetual water treatment by transforming salt into natural chlorine that disinfects and sanitizes the pool. Its operation is simple: the water passes through the electrolyzer, which decomposes the salt water into sodium hypochlorite or active chlorine thanks to electrical energy. The result is disinfected, clear, slightly salted pool water that does not irritate the skin and does not sting the eyes.
The process repeats indefinitely because the active chlorine reverts to salt under the action of the sun's UV rays.
The salt electrolyzer consists of:
- a cell in which the electrolysis of the salt water occurs and which contains electrodes;
- electrodes that come in the form of plates or grids;
- an electrical box that allows it to be powered and to control its operation.
The electrolyzer is chosen based on the volume of the pool to be treated. This treatment volume is often mentioned on the product.
Pool electrolyzers are generally equipped with a flow and salt quantity detector, and also a pH meter to optimally regulate water treatment and its functioning. The most advanced models also detect if the pool is covered and reduce the electrolysis accordingly to stabilize the water quality.
The maintenance of the pool electrolyzer is limited to adding salt to the pool water to maintain its level between 3 and 5 g/L and to the replacement of the cell when the electrodes are worn and eroded. The electrodes are more durable when the electrolyzer has an option for automatic polarity reversal that destroys limescale deposits.
The purchase of a pool electrolyzer is a wise and sustainable investment for those who wish to fully enjoy their pool safely.
