DEIONIZER
REW-198
Product Derails :
- Water
is one of the most abundant natural elements. It is also one of the most
contaminated ones. A number of minerals dissolve into water. They have to
be removed from the raw water before it can be used for any industrial
application.
- A demineraliser removes these minerals from the raw
water by an ion- exchange process. This process first exchanges the
cations of the salts for the hydrogen ions and, then exchanges the anions
of the salts for the hydroxy ions. "MAC" water demineralisers employ
the modern on- exchange technology to give you chemically pure water.
- In these days Softening of Water is almost
exclusively effected by Ion Exchangers. In this process the calcium and
magnesium ions are exchanged by sodium ions, so that the hardness forming
components are converted into sodium sodium salts. Softening is carried
out by simple filtration through the exchange material.
- When the exchange material is exhausted, it
requires regeneration. The calcium and magnesium ions which were taken up before
are then displaced by sodium ions and flow out together with the
regeneration water. The capacities between regeneration and quality of
treated water will however vary according to the raw water.

DOUBLE BED UNIT (CA)
- SAI Deionizer consists of an in - built prefilter
and very high exchanging capacity non - corrosive CATION and ANION resin
columns prefilled with RESINS for efficient results having treated water
parameter conforming to IS-1069 / 64. It yields chemically pure water
equal to multiple distilled water having a conductivity of less than 10
micro-siemens /cm and pH of 7.5 to 9 pH. Fitted with a sturdy PVC multi -
control valve and can be connected direct to water taps. Fitted with
digital conductivity meter. Supplied with one plastic chemical proof
regeneration tank. Complete unit in housed in a painted M.S trolley for
easy mobility.
- Basic models consisting of a CATION and ANION
column for general laboratory applications where municipal tap water
quality is generally good and fall in the range of upto 300 ppm. For hard
ground water as a input source these models breakdown frequently requiring
frequent regeneration processes and thus damaging resins of cation and
anion columns.
FEATURES
- Unique digital conductivity meter fitted with unit.
- In-built pre filter.
- Upflow Treatment.
- Can be connected direct to water tap.
- Treated water will have the conductivity less than
10 ms/cm and pH of 7.5 -9.
- Non Corrosive Regeneration Tank.
- High capacity Cation & Anion exchange resins.
- Easy portable - metal stand and trolley.
- Simple periodic regeneration - negligible operating
costs.

DOUBLE STAGE DOUBLE BED
UNIT
For input tap/
raw water having TDS between 500- 600 ppm it is advised to install two DOUBLE
BED UNITS (CA Series) of the same capacity in combination / series . This
system works as a DOUBLE STAGE DOUBLE BED UNIT (i.e CATION-ANION-CATION-ANION)
to achieve a conductivity of less than 10 ms/cm and a pH of 7.5-9.0.

Output/hr (ltrs) | 300 | 500 | 750 |
DOUBLE BED MIXED BED UNIT
For input tap/
raw water having TDS upto 300 ppm, it is advised to install MIXED BED UNIT (MB
Series) in combination/series to a DOUBLE BED UNIT (CA Series) of the same
capacity (i.e CATION-ANION-MIXED BED) to achieve a conductivity of less than 2
ms/cm and pH of 6.8-7.2.

MIXED BED
UNIT (MB)
FEATURES
- Unique digital conductivity meter fitted with unit.
- MB Unit has to be operated a polishing unit running
in series with CA or FB Model demineralisers.
- Due to intimate mixing of Cation & Anion Resins
in as single column the demineralised water is of consistenly neutral
purity.
- Electrical Conductivity of the deionised water is
less than 1 ms/cm and pH is 6.8 - 7.2.
- Treats water having TDS from 50-100 ppm.
- Digital Conductivity meter operates on AC.
- Air displacement systems.
- Clean continuous ion exchange process.
- Multivalve Systems for easy operation &
regeneration..
- Easily portable metal stand and trolley.
Mixed bed units are normally operated as a POLISHING UNIT
running in series with a double bed CA Model or a four bed FB Model of a
similar capacity / flow rate. Due to intimate mixing of Cation and Anion exchange
resins in a single column the final water produced is of consistently neutral
quality with conductivity of water being less than 2 ms/cm and pH of 6.8 - 7.2.
These independent Models can be ordered for your existing CA/FB Models. Models
of capacity MB 300 and above need MINI Air Compressor for resin mixing. And
this has to be arranged by the customer on their own or can be supplied at
extra cost.
