Water Treatment Processes:

One of the more general water treatment techniques is the use of demineralizers and ion exchange.  This techniques will be elaborates in this theory.

 DEFINE the following terms:

a. Ion exchange         e. Polymer

b. Demineralize           f. Mixed-bed demineralizer

c. Cation                     g. Affinity

d. Anion                      h. Decontamination factor

 DESCRIBE the subsequent:

a. Resin bead

b. Cation resin

c. Anion resin

 DISCUSS the given factors of ion exchange:

a. Relative affinity

b. Decontamination factor

 WRITE the reaction for removal of NaCl and CaSO₄ through a mixed-bed ion exchanger like as one containing HOH resin.
