    What to know before buying swimming pool salt.


    Need to stock up on swimming pool salt? Things to look out for.

    Increasing numbers of people who are having a swimming pool put in, are opting for salt electrolysis to disinfect their swimming pool water. With good reason. The process of electrolysis converts swimming pool salt into chlorine, but without the unpleasant smell or stinging eyes. With clean, fresh water as a result. Careful though: Not every type of salt is suited for disinfecting swimming pools. So do not buy just any type of salt.

    1.    Does the swimming pool salt damage the swimming pool in any way?

     

    European standard EN 16401 lays down the composition, the level of purity and moisture content requirements which swimming pool salt needs to comply with. This is specifically aimed at the treatment of swimming pool water with an electrochlorinator.

    • The salt needs to have a purity level of at least 99.4% NaCl (sodium chloride).
    • The standard defines maximum values for metals such as copper, iron and magnesium.
    • The salt is not allowed to contain additives such as anti-caking agent (E535 or E536) or iodine.

    Failure to comply with this standard may potentially damage the electrochlorinator or produce stains in and on the swimming pool basin and equipment.

    2.  Has the swimming pool salt been tested for safety?

     

    The use of biocides is strictly regulated in Europe. Biocides are used to neutralise organisms. They include insecticides, algicides, mouse poison, disinfectants, fungicide, etc.

    In actual fact, swimming pool salt (sodium chloride) is not a biocide but a raw material or input for chlorine. Since 2014, this type of ‘precursor’ also comes under the application of the Biocidal Products Regulation BPR 528/2012. To ensure a high level of protection of human and environmental health, this regulation bans the use of biocides and precursors that contain the following substances:

    • carcinogenic, mutagenic and reproduction-toxic substances
    • endocrine-disrupting substances
    • persistent, bio-accumulative and toxic substances (PBT substances)
    • highly persistent and highly bio-accumulative substances

    Swimming pool salt which complies with the Biocidal Products Regulation has been extensively tested for safety and may therefore be used with confidence. The use of unregistered swimming pool salt has been banned.
