Liquid deionizing twin bed apparatus

A liquid deionizing twin bed apparatus for use in conjunction with a 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 two liquid permeable containers, wherein at least one of said liquid permeable containers defines 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, and the other of said two liquid permeable containers defines 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 the vessel relative to fluid flow therethrough and said at least two liquid permeable containers being adapted to be removingly housed within the vessel for removing spent anionic and cationic materials and replacing spent anionic and cationic materials by inserting new liquid permeable containers having unspent anionic and cationic materials into the vessel.

A liquid deionizing system comprising:

• a pressure vessel having an inlet for receiving untreated ionized liquid and an outlet through which the treated deionized liquid exits said vessel;
• and
• 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 spent anionic and cationic materials by inserting a new liquid permeable container having unspent anionic and cationic materials into the vessel.
