Tablet salt for water softeners – how does it work and why is it worth it?

What is water hardness?

Water hardness is the concentration of calcium (Ca²⁺) and magnesium (Mg²⁺) ions. Hard water causes scale deposits in boilers, laundry rooms and central heating installations, shortening their life and increasing energy consumption.

Mechanism of action of the ion exchange softener

The softener contains a cation exchange resin charged with sodium ions (Na⁺). As hard water flows through the bed, Ca²⁺ and Mg²⁺ ions are retained and Na⁺ ions are released - the water becomes soft.

The role of tablet salt in regeneration

After some time, the resin becomes saturated with calcium and magnesium ions. Regeneration involves rinsing the bed with NaCl brine solution - Na⁺ ions displace Ca²⁺ and Mg²⁺, the resin returns to its initial state.

• Tablet salt ≥99.5% NaCl - minimum content of impurities
• 25 g tablets - optimal dissolution rate
