The softener: the solution against hard water

You should really protect your equipment from hard water.

First you should test your water,since the TH rate will enable you to know whether you have hard water.

Beyond 15 degrees Th water is considered hard water. Beyond 20 degrees, it’s really hard water. The harder your water is, the more scale you get.

You have to know what to do in order to choose the best option.

What is water softening?

What is water softening?

Water softening takes place in 2 stages: ion exchange and regeneration.

  • The ion exchange
  • Regeneration

The ion exchange

A water softening system exchanges calcium and magnesium ions (which are little soluble and react with water carbonates to create hard water) with sodium ions which are water soluble. This is called ‘ion exchange’

The ionic exchange provided by the softener is carried out by the water passing on a solid support: the resin. The resin is made of neutral polymereloaded with sodium.


The first phase of softening is the exchange of calcium and magnesium in the water against the sodium on the resin.

This process goes on until there are no more sodium ions to enable a new exchange. This is actually generation.

Don’t mix up softeners and antiscales

Don’t mix up softeners and antiscales

Antiscale devices use different technologies, mainly electromagnetic, gavalnic or by polyphosphates.

These technologies fight the scale, preventing it to remain in the pipes on the internal surfaces but they do not suppress it.

We advise these technologies for medium or hot waters (<25°th).

The softener is the only device that physically removes limescale from the water.

Talassa's softeners

TALASSA water treatment products comply with health regulations

The softener is the only device which physically removes hard water.

It provides a soft and non irritating water.

TALASSA is the third French softener manufacturer. We produce 6000 softeners every year.
