In order for your pool water to be in the best possible condition, its physical and chemical properties must remain constant. This is the aim of our water disinfection and treatment systems. Among the most sustainable and healthy, two stand out: salt chlorination and neolysis.

Salt chlorination consists in using table salt as a pool disinfectant. This is an extremely straightforward water treatment system as inflammable chemical products do not have to be used or handled. In addition, as only table salt, a stabiliser (the first time) and a pH reducer are required for treating the water, a 90% saving is made on chemical products.

The first step in salt chlorination is to add 4 grams of salt for every litre of water in a pool. As a rough guideline, this proportion of salt is nine times less than that found in seawater. When the salt has dissolved, an electric current is conducted through an electrode that turns it into chlorine. The power consumption of this process is similar to that of a light bulb.

Once the chlorine has eliminated all microorganisms from the water, it is turned back into salt. Thus, the concentration of salt in the water remains practically constant. Just a few top-ups are needed to make up for losses caused by backwashing the filter.

In the case of neolysis, a single reactor combines the production of chlorine from salt with another interesting disinfection system: UV radiation. UV treatment is based on the use of UV lamps that change the DNA of any microorganisms in the water and inhibit cell reproduction.

By coupling the sterilising action of the two methods, neolysis – a process patented by Fluidra the concentration of chloramines (which are produced when chlorine comes into contact with organic compounds such as sweat and certain cosmetics) is greatly reduced and only requires the addition of 2 grams of salt per litre of water. This low level of salt makes pool water suitable for watering gardens, which further increases a pool’s sustainability.

Both salt chlorination and neolysis are efficient ways of disinfecting water and they do not cause the discomfort that chlorine usually does: strong odours, unpleasant taste of water, sore eyes, irritated mucous membranes, and dry skin and hair. Moreover, the clean, healthy water gives a greater feeling of enjoyment and wellbeing, thus making every swim an unforgettable experience.
