Two Bed Deionization System
consists of two separate columns each containing different
type of resins.
The first column
usually contains cation resins while the second column
in series contains anion resins. The two resin columns
work together to remove cations and anions from the
feed water. The effluent quality from a typical Two
Bed DI System can reach 1 Mohm-cm.
Two Bed DI System
can either be placed downstream of a Reverse Osmosis
(RO) System to increase the quality of the RO permeate
or be used without the RO System. In the latter case,
the service life of the Two Bed DI system is only
about one twentieth of that of the former. |
