          Summary


          Challenge    Improve condensate polishing to ensure that suspended solids and dissolved impurities in the water
                       do not critically damage expensive power plant components including boilers, steam generators,
                       and turbines. Improperly treated process streams also increase boiler blow down frequency, reduce
                       heat transfer effi ciencies, and cause unexpected downtime.


          Solution     Cartridge fi lters are a valuable component in the power plant condensate polishing stream.
                       Parker’s ParMax fi lter vessels and large diameter cartridges effectively remove solids which ensure
                       adequately polished condensate and effi cient ion exchange within demineralizer beds.

          Results      Improving the effi ciency of condensate polishing systems reduces the frequency of replenishing ion
                       exchange resins thus reducing maintenance costs, unexpected downtime, while improving plant
                       wide system performance.
