Operating Principle
A Typical two-bed Demineralised Water plant or DM Plant consists of FRP/MS Rubber/SS 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 7 S / cm at 250 C and total dissolved solids less than 4 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.
De-gasifiers
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, there by 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.
Condensate Polishing
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 environmental impact.
DM Water
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.
