Mix Bed Plant
In mixed-bed deionizers the cation-exchange and anion-exchange resins are intimately mixed and contained
in a single pressure vessel. The thorough mixture of cation-exchangers and anion-exchangers in a single
column makes a mixed-bed deionizer equivalent to a lengthy series of two-bed plants. As a result, the
Water quality obtained from a mixed-bed deionizer is appreciably higher than that produced by a two-bed
plant. Although more efficient in purifying the incoming feedWater, mixed-bed plants are more sensitive
to impurities in the Water supply and involve a more complicated regeneration process. Mixed-bed
deionizers are normally used to ‘polish' the Water to higher levels of purity after it has been initially
treated by either a two-bed deionizer or a reverse osmosis unit.
Further high purity water can be achieved after d.m.plant by Mixed Bed Deionisers, which are designed to produce high purity treated water. They can be used as polishing units after two beds DM Plant to obtain high purity water. Mixed Bed Deionisers are single column units, filled with strongly acidic cation and strongly basic anion exchange resins mixed together.
Water Quality (Conductivity) from Mixed Bed Outlet will be less than 1 micro siemens.
