Abstract:
A liquid deionizing twin bed apparatus for use in conjunction with pressure vessel having an inlet for receiving untreated ionized liquid and an outlet through which the treated deionized liquid exits the vessel, said apparatus comprising:at least one liquid permeable container, said container having an anionic exchanger bed containing anionic materials adapted to absorb one type of charged particle from the fluid and requiring one type of regenerating agent to strip charged particles from said anionic materials, said container also having a cationic exchanger bed containing cationic materials adapted to absorb oppositely charged particles from the liquid flowing therethrough and requiring a different type of regenerating agent to strip charged particles from said cationic materials, said anionic and cationic beds being positioned in series in said liquid permeable container relative to fluid flow therethrough and said at least one liquid permeable container being adapted to be removably housed within the vessel for removing spent anionic and cationic materials and replacing spend anionic and cationic materials by inserting a new liquid permeable container having unspent anionic and cationic materials into the vessel.
