Cationic resin for water softeners in 25 Lts

what is cationic resin?

25 litre sack of cationic resin for water softeners

The passage of water through sedimentary rocks such as limestone causes two of the most common ions in natural water to be calcium and magnesium. These, when found in high concentrations, are responsible for water hardness, causing incrustations in pipes, machinery, household appliances, etc.

One of the ways to eliminate water hardness, thus avoiding these problems, is decalcification. Softeners work by means of ion exchange resins (Cation Resin).

Cation Resin is a synthetic product that is manufactured in the form of tiny spherical particles. This is where the ion exchange takes place. The cation resin spheres attract positively charged ions or cations. The cations will remain attached to the resin until it comes into contact with other cations for which it has a higher affinity. What happens is that the resin will release an ion and accept in its place the ion for which it has more attraction.

In the decalcification process calcium and magnesium have more affinity for the resin than sodium. The resin will release the sodium ions to make room for the calcium and magnesium ions. Thus the calcium and magnesium are partially removed, resulting in less hard water.
