Demineralisation Plants, DM Plant in India
Demineralisation is the process of removing mineral salts from water by using the ion exchange process. With
most natural water sources it is possible to use Demineralisation and produce water of a higher quality than
Fluid Systems Manufacture a Wide range of custom-built Demineralised Water plant [DM Plant] in India for
industrial process water applications, with inherent design to conserve water, and save costs. The DM Plants
[Demineralisation Plants] are available in different sizes and materials, manually operated or fully
Automatic, & ready to install & are available as standard models or custom built versions for specific
A Typical two-bed Demineralised Water plant or DM Plant consists of FRP/MS Rubber lined Pressure vessels
connected in series along with its internal fittings. The first unit consists of high capacity strongly acidic
cation exchange resin, which converts positive ions of salt and replaces them with hydrogen ions to form
respective acids, which are absorbed in next vessel by strongly basic anion exchange resin. The water obtained
by this process shows conductivity less than 20 µ S / cm at 250 C and total dissolved solids less than 10 ppm.
Further high purity water can be achieved by Mixed Bed Deionisers, which are designed to produce high purity
treated water. They can be used as polishing units after two bed DM Plant to obtain high purity water. Mixed
Bed Deionisers are single column units, filled with strongly acidic cation and strongly basic anion exchange
resins mixed together.
Degassifier unit is a part of a DM Plant In which, we offer a full range of degassers to suit the packaged
/custom-made Demineralisation Plants [DM Plants]. Degassers when installed downstream of the cation unit
removes the carbon dioxide, thereby reducing the load on the Anion unit. This results in cost savings by way
of reduced chemical consumption. Standard units comprise of a tower in mild steel rubber lined / FRP
construction along with a blower and transfer pump in stainless steel construction. Additional pump and
blowers are offered as options.
Mixed Bed De-mineralisers
Mixed bed de-mineralisers are used on the downstream of the DM unit to achieve high purity levels in the
treated water. We confer packaged and custom-built mixed bed de-mineralisers. These mixed bed units comprise
of a single vessel with a mixture of cation and anion resins and are offered with complete service and
regeneration piping, self supportive skid foundation and chemical tanks for regeneration.
A condensate polisher is a device used to filter water condensed from steam as part of the steam cycle. Our
superior condensate polishing ion exchange resins excel in capturing corrosion products in the condensate
stream. This polishing typically involves ion exchange technology for the removal of trace dissolved minerals
and suspended matter. It is generally used as part of a power plant's condensate system and prevents premature
chemical failure and deposition within the power cycle which would have resulted in loss of unit efficiency
and possible mechanical damage to key generating equipment.
Fully Automatic Rapid Flow Two Bed DM Plants
Fluid Systems Offer Skid Mounted, PLC Controlled Two Bed Fully Automatic Rapid DM Plants incorporating
state-of-the-art counter flow ion exchange technology previously available only in large, purpose-designed
plant. The operational cycle of these rapid-regeneration, packaged units is controlled by volume throughput,
which is pre-programmed into the PC according to the type of feed water. The ion exchange resins are never
fully exhausted ensuring optimum deionised water production at all times.
Regeneration takes just 30 minutes - after a minimum service cycle of two hours – minimizing the need for both
standby plant and the storage of large volumes of water. As regeneration of the cation and anion beds is
simultaneous, the effluent streams are largely self-neutralising, reducing waste disposal costs and
We also supply DM water in bulk quantities for water needs in manufacturing and production process. We have
vast experience in providing high quality DM water to industry. We have highly qualified & educated staff
who understands high quality water needs. For Bulk quantity of DM water, we install a Two Bed DM Plant/ Three
Bed DM Plant at the customer premises.
