Protecting
Liquid Processing Streams
 Naturally
occurring impurities are present in all
raw water supplies, and will be
introduced in the process operation or
end product when untreated water
is used. Typical impurities are calcium,
magnesium, sodium, alkalinity,
chlorides, sulfates, nitrates, and
silica. All of these contaminants
cause scaling in boilers, spotting on
finished surfaces, precipitation in
chemical products, defects in electronic
components as well as other problems in
each process application. The EBD
Water IED Ion Exchange Systems will reduce these contaminants to
negligible levels.

Principles
of Operation
An
EBD Water IED Demineralizer is a
complete system utilized to deionize
water or other liquids to an acceptable
level for various industrial uses.
The
EBD Water Demineralizers can be used as
primary or polishing Ion Exchangers.
When used as a primary ion-exchanger
following an EBD Water Reverse
Osmosis System, water of 10 - 18 megohm
is produced. As a polisher,
an EBD Water Demineralizer can produce
water of up to 18.3 megohm quality.
EBD
Water Demineralizers consist of single
or multiple two bed or mixed bed units,
depending upon production requirements
and the degree of purity needed for a
particular process. Because of the
characteristics of the raw water supply,
many systems require cation and anion
exchangers of unequal sizes to obtain
optimum performance. The addition
of a decarbonator for the removal of
will reduce the load on the anion
exchanger.
Weak
base resins are used to produce low
solids water, however silica and
are not removed by these units and
require the use of strong base.
