Anyone who is looking for a safe and high-quality precursor for electrochlorination can always rely on ZOUTMAN.

Salt and biocides – what is the connection?

When making a biocide such as chlorine on site, a precursor is essential. Put simply, this is a substance that precedes another substance. Salt (sodium chloride), and more specifically salt that is used for electrochlorination, is a precursor for making chlorine.

There is European legislation on precursors too

While the European legislation initially seemed to be vague about precursors, since 1 September 2015 precursors for creating biocides have needed to be registered. Ever since then it has been forbidden to use salt that does not appear on the list of registered products (ECHA Art. 95) for electrochlorination. Nevertheless, we recommend that as a user or seller of precursors you remain alert. Salts that are not suitable for biocides still appear from time to time. Anyone who uses or sells these, whether knowingly or not, is also held responsible.

How do I know which salt is suitable for biocides?

Do you want to be 100% certain that you are purchasing or selling salt that is suitable for biocides? The best thing to do is to ask your supplier for a certificate. In the Belgian market, you only need to look at the notification number on the product. This is stated on the packaging by law. All items with the description ‘Notif’ combined with a four-digit code are suitable for biocides.
