Principles of ions exchanging

Marine Autocontrol Water Softener is designed and

manufactured according to latest technology,It’s controlled by time brine

refill and meter setting procedure, can work continuous 24 hours around . It

has two resin tanks, one work the other one stand by. and regeneration.

Hardness of water consists of those ions (mainly Calcium and Magnesium)

which can give rise to scaling.

Softening is attained by the replacement of hardness ions with Sodium ones

(which have no scaling capacity) by means of ion exchangers ( resin). As

soon as the exchanger has exhausted its exchange capacity, it becomes

necessary to regenerate it. This is attained by having a solution of Sodium

chloride (table salt) percolate through the mass of resin.

The service-regeneration cycle is automatically effected by softeners which

essentially consist of a pressure tank (housing the exchanger bed) and a

brine tank.

Schematically, the exchanger can be considered as a long organic

molecule (undissolvable in water and food-grade) with a large number of

Sodium (Na) ions bound to it. As the resin, however, has a higher chemical

affinity to Calcium (Ca) and Magnesium (Mg) ions, it follows that it has a

natural capacity for releasing Sodium ions.

In the regeneration step there is a very high concentration of Sodium ions

and as a result of its mass, the resin is forced to release Calcium and

Magnesium ions thus going back to the original Sodium form and therefore

restoring the exchange capacity.
