Mixed bed resins use SAC and SBA resins combined together. ... As positively charged cations flow across cation resin beads, the cations are exchanged for hydrogen (H+). Likewise, as negatively charged anions flow across anion resin beads, the anions are exchanged for hydroxyl (OH-‐)
What does anion resin remove?
Anion dealkalizers are primarily used to remove alkalinity from boiler feedwater with a low-to-moderate amount of total dissolved solids (TDS). Anion dealkalizers may also be used to remove carbonate, bicarbonate, sulfates and nitrates from feedwater.
