Ion Exchange Process:-

CATION UNIT

1. 	The raw water is liable to vary from time to time and E.M.A. is therefore, likely to change and should be checked regularly.  To control rinsing, continue rinsing until two successive test for F.M.A. give the same figure for F.M.A.

2. 	Regenerate Cation when F.M.A. begins to fall from its normal steady value.

3. 	If the Sodium to Total Cation ratio increases, there is a danger that slip will increase beyond tolerable limits.  The treated water conductivity and pH will be high.  In such instances, an increased quantity of acid should be used for regeneration.

4. 	The capacity is proportional to total Cation content of raw water.  A regular comparison between actual Tc and designed Tc will give an indication of the capacity to be expected.



ANION UNIT
1. 	The Cation outlet water is inlet water to Anion.  This water will be acidic to Methyl Orange.  It will also contain some free CO2 about 6 ppm if a degasser is installed.

2.   The water leaving the Anion unit will be Alkaline to Methyl Orange and initially free                                                                                                                   
        of CO2 Chloride, Silica. The conductivity of anion outlet water is a direct measurement 
       of purity.

3. 	For many purposes this water is directly taken to process or if higher purity is required then acts as inlet water to Mixed Bed Polishing Unit.

Caution :-  1) Do not backwash Counter current Regenerated Unit every time you take the                                  	               unit for regeneration.  It can be carried once after every 10-15 regeneration.

2) 	Always use treated water for dilution of chemicals and also for power water.  Use 

Cation water for power water for regeneration of Cation unit
      and Anion water for regeneration of Anion Unit.

3) 	The quality of water obtained after Anion Unit is dependent on the Cation water entering it.  Any Sodium slip from Cation Unit is converted to NaOH in the Anion Unit.
	
4) 	1ppm of NaOH in treated water results in a conductivity of 5-6  s/ cm.  Presence of NaOH in the D. M. water results in its having a high pH and Phenolphthalein Alkalinity
