Demineralized water also known as Deionized water, water
that has had its mineral ions removed. Mineral ions such as cations
of sodium, calcium, iron, copper, etc and anions such as chloride,
sulphate, nitrate, etc are common ions present in water.
Deionization is a physical process which uses
specially-manufactured ion exchange resins which provides ion
exchange site for the replacement of the mineral salts in water
with water forming H and OH- ions. Because the majority of water
impurities are dissolved salts, deionization produces a high purity
water that is generally similar to distilled water, and this
process is quick and without scale buildup.
De-mineralization technology is the proven process for treatment of
water. A DM Water System produces mineral free water by operating
on the principles of ion exchange, Degasification, and polishing.
Demineralized Water System finds wide application in the field of
steam, power, process, and cooling.
Principle :
Raw water is passed via two small polystyrene bead filled (ion
exchange resins) beds. While the cations get exchanged with
hydrogen ions in first bed, the anions are exchanged with hydroxyl
ions, in the second one.
Process :
In the context of water purification, ion-exchange is a rapid and
reversible process in which impurity ions present in the water are
replaced by ions released by an ion-exchange resin. The impurity
ions are taken up by the resin, which must be periodically
regenerated to restore it to the original ionic form. (An ion is an
atom or group of atoms with an electric charge. Positively-charged
ions are called cations and are usually metals; negatively-charged
ions are called anions and are usually non-metals).
The following ions are widely found in raw waters :
Cations Anions
Calcium (Ca2 ) Chloride ( Cl-)
Magnesium (Mg2 ) Bicarbonate (HCO*-)
Sodium (Na ) Nitrate (NO*-)
Potassium (K ) Carbonate (CO**-)
Ion Exchange Resins :
There are two basic types of resin - cation-exchange and
anion-exchange resins. Cation exchange resins will release Hydrogen
(H ) ions or other positively charged ions in exchange for impurity
cations present in the water. Anion exchange resins will release
hydroxyl (OH-) ions or other negatively charged ions in exchange
for impurity anions present in the water.
The application of ion-exchange to water treatment and
purification. There are three ways in which ion-exchange technology
can be used in water treatment and purification :
first, cation-exchange resins alone can be employed to soften water
by base exchange; secondly, anion-exchange resins alone can be used
for organic scavenging or nitrate removal; and thirdly,
combinations of cation-exchange and anion-exchange resins can be
used to remove virtually all the ionic impurities present in the
feedwater, a process known as deionization. Water deionizers
purification process results in water of exceptionally high
quality
Deionization :
For many laboratory and industrial applications, high-purity water
which is essentially free from ionic contaminants is required.
Water of this quality can be produced by deionization.The two most
common types of deionization are :
Two-bed deionization :
The two-bed deionizer consists of two vessels - one containing a
cation-exchange resin in the hydrogen (H ) form and the other
containing an anion resin in the hydroxyl (OH-) form. Water flows
through the cation column, whereupon all the cations are exchanged
for hydrogen ions. To keep the water electrically balanced, for
every monovalent cation, e.g. Na , one hydrogen ion is exchanged
and for every divalent cation, e.g. Ca2 , or Mg2 , two hydrogen
ions are exchanged. The same principle applies when considering
anion-exchange. The decationised water then flows through the anion
column. This time, all the negatively charged ions are exchanged
for hydroxide ions which then combine with the hydrogen ions to
form water (H2O).
Mixed-bed deionization :
In mixed-bed deionizers the cation-exchange and anion-exchange
resins are intimately mixed and contained in a single pressure
vessel. The thorough mixture of cation-exchangers and
anion-exchangers in a single column makes a mixed-bed deionizer
equivalent to a lengthy series of two-bed plants. As a result, the
water quality obtained from a mixed-bed deionizer is appreciably
higher than that produced by a two-bed plant.
Although more efficient in purifying the incoming feedwater,
mixed-bed plants are more sensitive to impurities in the water
supply and involve a more complicated regeneration process.
Mixed-bed deionizers are normally used to polish\' the water to
higher levels of purity after it has been initially treated by
either a two-bed deionizer or a reverse osmosis unit.
