Ion exchange is a well established method for purifying water
by trading ions in solution with ions held on resin reaction
sites. Mixed Bed Ion Exchangers contain a precise mixture of
cation and anion resin. Cation resin exchanges hydrogen (H+) for
cations (i.e. sodium), while anion resin exchanges hydroxyl
(OH-) for anions (i.e. chloride). Hydrogen and hydroxide combine
to form water, thereby purifying the incoming water.
Mixed resin beds generate higher water quality (~18 Megaohm-cm,
depending on feedwater quality) than is achievable by
conventional two bed ion exchange.
SAMCO's Automatic Mixed Bed DI Systems (AMB) are available
complete with all necessary piping controls and automation skid
mounted to minimize maintenance and space requirements.
