Mixed Bed Ion Exchange Animation

Your browser does not support the HTML5 canvas tag.

Mixed bed is better than using first one ion exchange resin to remove cations and then another to remove anions because having both resins in very close proximity creates a stronger driving force as the hydrogen ion exchanged at one resin attracts a hydroxyl ion from the other resin to form water.

Deionized water is usually an excellent substitute for distilled water and is less expensive.

The mixed bed process is conducted in plastic vessels to resist acid corrosion, and faulty balancing of flows during regeneration can generate so much heat from acid reacting with base that steam forms and the plasitic melts, but with proper flow adjustments and automation, mixed bed ion exchange is quite reliable.
