Condensate Polishing Filters

Read F.A.Q.

Electric generating station condensate must be maintained at a very high purity level to protect boilers, steam generators, reactors, and turbines from corrosion. To remove contaminants from the condensate, deep bed ion exchange condensate polishers are used and sometimes preceded by a Powdex® filter demineralizer or a fine particulate filtration system. A Powdex system can also stand alone as the primary polisher. Graver Technologies is the most experienced and knowledgeable Ion Exchange product and Filter Septum manufacturer and offers the most complete range of products to meet today’s challenges. Whether the need is for high purity Gravex® condensate polishing ion exchange resins; the original Aegis® wound, DualGuard® or AFA® pleated filter septa; or the Powdex & Ecodex® families of premium resins, the original and most widely used powdered ion exchange resins, Graver Technologies has the answer for your application.

  • Aegis precoatable filter septa for Powdex filter demineralizers
  • AFA, the first backwashable pleated filters installed in a condensate pre-filter system
  • DualGuard, combination pleated filter with a precoatable and easily backwashable surface

Frequently asked questions

How to remove heavy metals from water and wastewater?
Many MetSorb® adsorbents will remove heavy metals from water and wastewater. Please view our product pages for more information.
Are heavy metals in water? Do they pose a threat to human health?
The USEPA issued and regularly reviews/updates the National Primary Drinking Water Regulations (NPDWR).
How can I remove lead from water?
Many MetSorb® adsorbents will remove lead and other heavy metals from water. Please view our product pages for more information.
How much uranium is safe in drinking water?
The USEPA has issued and regularly reviews/updates the National Primary Drinking Water Regulations (NPDWR).
Why do MetSorb® adsorbents sometimes have a bad smell and how do we get rid of this odor?
MetSorb® adsorbents are made from metal oxides and rarely have any noticeable smell. They can sometimes concentrate bacteria (specifically sulfur reducing) that may be present in the drinking water well source. While this type of bacteria is naturally found in many well sources and are considered harmless, the resulting “rotten egg” smell can be unpleasant. In order to remove the bacteria from the MetSorb® media bed, we recommend performing a 25-50 ppm chlorine shock for 12-24 hours. The system should then be rinsed with fresh water until no residual chlorine odor is noted. If bacteria count in the well water is high, this chlorine shock of the MetSorb® media may be required 2 or 3 times per year.
How can uranium be removed from well water?
One way uranium can be removed is through adsorption. MetSorb® HMRG has a selective affinity for uranium.
