In order to achieve crystal clear and healthy pool water, disinfection of the pool water is essential. We offer you chlorine disinfection equipment which, compared to chlorine tablets and other chlorine products, is more environmentally friendly and kinder to your body.
Our tip: You can also try chlorine-free water treatment using a device that uses UV light to kill algae and bacteria.
Disinfecting pool water by dosing chlorine or hypochlorite
Disinfecting pool water with chlorine by hand or with tablets is of course very cheap, but also time-consuming. It also requires at least a basic knowledge of pool chemistry and frequent measurements of the pool water, based on which the required amount of disinfection is applied.
Nowadays, when the vast majority of customers do not want to spend time on pool water treatment, the installation of an automatic chlorine dosing station is much more popular. Although this option is significantly more expensive in terms of purchase cost, it can save a lot of time. The station itself measures the pool water during filtration and, based on this measurement, applies the necessary amount of disinfectant and other cleaning chemicals to the pool.
Disinfection of pool water by electrolysis of salt water
There is a huge range of pool equipment on the market, of all sizes and designs, that works on the principle of salt water electrolysis. This is a solonisation technology that uses a low concentration of salt water (up to 0.4%) for disinfection. This method of chlorine disinfection of pool water is environmentally friendly even for the skin of sensitive individuals.
How salt water solonisation works in a swimming pool
All solonisation units work on the same principle of saltwater electrolysis. During the controlled electrolysis process, chlorine gas, oxygen and, to some extent, ozone are released into the water.
The whole process starts by adding natural sea salt to the water. This produces clear, slightly salty water with a salinity of between 0.3 and 0.4 %. The salinity of the ocean, by contrast, is 3.5 % and the salinity of a human tear is 0.6 %. The flow of water through the electrolytic cell and the application of an electric current of a safe voltage of 4,7 V DC results in the formation of chlorine gas at the anode. At the same time, other sanitising agents - oxygen and ozone - are produced during this process, while calcium and iron are removed from the water. No salt is consumed during the process as it is a regenerative chemical conversion process.
Does the salt used to sanitize pool water cause corrosion?
Water with a salinity of 0.3-0.4% is slightly corrosive, but no more so than normal chlorinated water. Metal components of filters and pumps and modern corrosion-resistant materials (PVC) do not react to such low salinity. However, the use of other metal or stainless steel components is not suitable for a saltwater pool.
Will the pool water be as salty as the ocean?
That is up to you. Most solonisation units can work with salinity levels as low as 0.3-0.4%, where the water is as salty as human tears. However, if you wish to have "sea water" in your pool, you need to bet on a different method of disinfection. Most solonisation units cannot handle salinities higher than 0.5%.
Why is the resulting water healthier?
Slightly salty water is a natural antiseptic and kills microorganisms commonly found in pool water. This makes the water healthier right from the start. Electrochemical disinfectants are produced that reliably destroy all bacteria and other harmful organisms. In the hotter months, when the pool water is at its hottest, a variety of thermophilic algae can form, which are resistant to disinfection at water temperatures above 30 °C, and an algaecide or UV lamp suitable for use in salt water must be dosed into the pool.
When to start disinfecting pool water?
For disinfection to work properly, it is very important that the pH of the water is between 6.8 and 7.4. If the values are higher or lower, the pH of the water needs to be adjusted and only then can you start disinfecting the water. That is why we only install saltwater solonisation pools with an automatic dispenser to adjust the pH of the pool water.
Benefits of disinfecting pool water with salt water solonisation
Solonisation units are one of the least expensive pool water disinfection devices. They can disinfect even in your absence, for example during a holiday. Compared to the systems used so far, salt water solonisation technology stands out for its increased respect for health and the environment.
In order to achieve complete disinfection of the pool water, we also offer other pool technologies or pool accessories. For example, you can choose from different types of vacuum cleaners, pool covers and pool canopies that prevent dirt from falling into the water. Our wide range of products also includes sand filtration systems.
