Ion-Exchange Demineralizers - to achieve reduced levels of contamination
Hungerford & Terry's superior custom-designed and custom-built demineralizers provide the very high purity levels required by modern processing applications. We achieve the low levels of mineral contamination required for your application by creating the best combination of H&T's proven demineralizer technologies.

Two Bed Systems
Improves conductance levels
A two-bed system works well for most applications even though demineralizers can vary greatly depending on the particular application. For a very high proportion of raw-water contamination levels, the first bed involves the removal of calcium, magnesium, and sodium using a cation exchanger with cocurrent acid regeneration. The second bed uses an anion exchanger with cocurrent caustic regeneration to remove alkalies, chlorides, sulfates, silica, and carbon dioxide. Engineering systems using this basic design typically achieve conductance levels of 5 to 10 µS/cm.

Countercurrent Regeneration Systems
For demineralization applications
If higher-quality water is essential, it is usually appropriate to use a countercurrent regeneration system to achieve conductance levels of less that 2 µS/cm. Hungerford & Terry is an industry leader in the design of countercurrent systems and is among the few companies supplying them in demineralization applications.

Boiler Protection
High-rate, deep-bed polishers remove residue material
Boilers are protected by Hungerford & Terry's condensate polishers. Our high-rate, deep-bed polishers remove suspended and dissolved material from returned condensate water through the use of mixed-bed demineralizers. These high-pressure demineralizers operate at a flow rate of 25 to 50 GPM per square foot of bed surface area. The boiler is further protected by the external regeneration of the bed, which prevents the intrusion of harmful acid and alkali into the return condensate. These polishers can operate beyond the ammonia break in high-pressure utility applications.
