• Product Description -

  The removal of CO₂ will assure (refer the Principle of reversible reactions) the removal of Carbonic acid from de-cationised water, consequently the reduction of Anionic load at Anion resin, without chemical addition, through a static column (known as De-gasser tower) filled with chemically inert media (to provide large surface / contact area required to break the Carbonic Acid into CO₂ & H₂O) with an arrangement of air – bubbling to strip – out the CO₂.

  Now this acidic water further passed through the bed of Ion exchange media present with Anion column (Hydroxide ion rich) - a reversible ion exchange reaction takes place and all the available anions (Cl-, SO4--, CO3-- etc.) get replaced with OH- ions, consequently water gets De-mineralized (H2O only) completely, in absence of ions or free radicals, earlier present with natural/ feed water. These could be explained as following:
  
  HC₁ + ReOH^-               ReC₁ + H²O
  H₂SO₄ + 2 ReOH^-       Re₂SO₄ + 2 H₂O          Reactions under Anion column
  H₂CO₃ + 2 ReOH^-        Re₂CO₃ + 2 H₂O

  These principles being used for manufacturing of Resin based De-Mineralization plant to make the available water free from salinity i.e. total dissolved solids for improvement of performance & life of various equipments & gadgets.

  SAF Engineers 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 (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 needs.

  Fully Automatic Rapid Flow Two Bed DM Plants

  SAF Engineers Offer Skid Mounted, PLC Controlled Two Bed Fully Automatic Rapid DM Plants incorporating state-of-the-art counter flow ion exchange technology. The operational cycle of these rapid-regeneration, packaged units is controlled by volume throughput, which is pre-programmed into the PPLC 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 60 minutes – after a minimum service cycle of four 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.

  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 (DM) Plants . Degassers when installed downstream of the cation (sometimes after RO) 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 fan blower and transfer pump in stainless steel construction. Additional pump and blowers are offered as options.

  Supercharge & Mixed Bed Polishers

  Supercharge & Mixed bed polishers are used on the downstream of the DM (Sometimes after RO) unit to achieve high purity levels in the treated water. We confer packaged and custom-built these polisher units.
  
  Supercharge Polisher is low cost, compact & simple unit, with single use supercharged resin while the Mixed Bed Polisher consists of a vessel with a mixture of cation and anion resins and are offered with complete service and regeneration piping & other components, self supportive skid foundation and chemical tanks for regeneration.

  Condensate Polishing

  A condensate polisher is a device used to filter the 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.
