The different water treatment systems

Catalytic system: "soft" technology to soften water

explanation of the process of catalytic filtration of limestone

Some manufacturers offer an ecological alternative to so-called conventional softeners with devices using a so-called catalytic method.
A resin precipitates the limestone in a nanocrystalline form, can no longer be transformed into scale, and assimilated by the body.
This process requires no energy or chemicals. It also allows to partially eliminate existing incrustations.
The taste of the water is not changed and the essential content of minerals and trace elements is preserved.
Unlike a conventional softener, this system does not release brine into the sewer and does not load the water into salt. The food resin, which requires no regeneration, changes every two years and simply throws itself in the trash. An original 100% environmental technology!

Softened water: what disadvantages

Too softened, the water attacks the metal of the pipes (especially below 6 TH).
In addition, a softener increases the sodium and potassium content of the water, which promotes hypertension (quantities are still very low) and rejects salt water in the sewers.
In addition, the regeneration of salts consumes a lot of water (140 to 400 l), which has a cost. For all questions relating to water treatment, contact CSTB (cstb.fr) or the UAE (uae.fr).
