DEIONIZATION
(DI WATER) WATER TREATMENT SYSTEMS
Deionization is an ion exchange process wherein all
of the positive ions (cations) in the water are exchanged with
hydrogen supplied by regeneration with acid and the negative ions
(anions) are exchanged with hydroxyl supplied by regeneration
with caustic acid. The combining of the resulting exchange products
hydrogen and hydroxyl (H+OH) yields H2O or water.The conductive
salts in the water are removed. Resistance of the water goes up.
- TWO COLUMN DEIONIZERS: 1.5
TO 75 GALLON PER MINUTE
- These series 700 and 7000 units
employ a standard control system developed in part by Dime
Water Inc. engineering. They consist of separate cation and
anion tanks made of fiberglass and are regenerated with commercially
available 30% hydrochloric acid and 50% liquid caustic soda.
Regenerant chemicals are used directly from the shipping containers
with no need for mixing or measurement, which minimizes the dangers
of handling. Units can be put into regeneration by means of a
warning signal and a push button in their simplest form, or can
be fully automated to regenerate based on a water quality decline.
Systems can be supplied that a regenerate the anion sacrificially
with water from the cation tank or a softened water source. Alternating
systems are also available that provide an uninterrupted deionized
water flow. Product water quality is a function of feed water
quality but is usually in the range of 50,000 to 500,000 ohms
(20 to 2 micro siemen) When the feed water is R.O. permeate,
qualities of 2,000,000 ohms (0.5 micro siemen) are obtainable.
Custom units with steel tanks,
special valves, custom controls, PLC controllers, sulfuric acid
cation regeneration, higher flows and special resins are available.
- MIXED BED DEIONIZERS: 5 TO
100 GALLON PER MINUTE
- With both resins mixed within
a single tank, proximity and the laws of mass transfer cause
a much higher removal of dissolved (cations and anions) in the
water. Typical results are in the 10,000,000 to 18,000,000 ohm
(0.1 to 0.55 micro siemen) range. These units are most commonly
found as post treatment to either a two-column deionizer or a
reverse osmosis unit. Water of such extremely high resistivity
(low conductivity) is used in the pharmaceutical or electronic
industries. After regeneration of the resins, they must be re-mixed.
A clean high volume of air is required for this very important
step.
All mixed bed units are custom
built with rubber or epoxy lined steel tanks. Control systems
are designed in concert with the customer. Calculated water chemistry
of the finished water is provided with quotations.
