What filters and resins are used in condensate polishing systems?

Condensate polishing systems use a combination of mechanical filters and ion exchange resins to remove impurities from the condensate. Mechanical filters are typically used to capture suspended solids and larger particles, while ion exchange resins target dissolved ions. Cation exchange resins remove positively charged ions, such as calcium and magnesium, while anion exchange resins remove negatively charged ions like chloride and sulfate. Mixed-bed resins, which combine both cation and anion resins, are used for final polishing to achieve the highest level of purity. Regular regeneration of the resins is essential to maintain system performance.
