boiler feed water softener hard scale removal
The Water Softener is used for boiler feed or in hot water piping, hard water will cause scale to form since most calcium and magnesium salts are less soluble at high temperature than at normal temperatures. sodium salts do not contribute to hard scale formation so water containing only sodium salts is called soft water. The convert hard water to soft waters the calcium and magnesium salts are removed or changed to sodium salts.
In the ion exchange softener, the hard water flows through the bed of strong acid cation exchanger which causes the calcium and magnesium ions in the hard water to be exchanged for sodium ions, so that the treated water turns to soft water.
The softening process may be illustrated by the following reactions
Ca (HCO3) 2 +2 Nar CaR 2 +Na HC03
Calcium Sodium Calcium Sodium
Bicarbonate Ion Exchange Ion Exchange Bicarbonate
Mg SO4
Magnesium Sodium Magnesium Sodium
Sulfate Ion Exchanger Ion Exchanger Sulfate

What do water softeners do?
Industrial water softeners are specific ion exchangers that are designed to remove ions which are positively charged.
Softeners mainly remove calcium (Ca2+) and magnesium (Mg2+) ions. Calcium and magnesium are often referred to as "hardness minerals". Softeners are sometimes even applied to remove iron.
The softening devices are able to remove up to five milligrams per liter (5 mg/L) of dissolved iron and can operate automatic, semi-automatic, or manual. Each type is rated on the amount of hardness it can remove before regeneration is necessary. Commercial water softeners collect hardness minerals within its conditioning tank and from time to time flushes them away to drain.
When an ion exchanger is applied for water softening, it will replace the calcium and magnesium ions in the water with other ions, for instance sodium or potassium. The exchanger ions are added to the ion exchanger reservoir as sodium and potassium salts (NaCl and KCl).
