6. Pretreatment of cation
exchange resin:
a. Clean water
After
the new resin is installed, it should be washed or soaked with normal
temperature water (hot water at 50-60℃ is better)
until the water is clear, colorless or less foams.
b. Dilute HCL
solution treatment
The
concentration is 4-5%, the dosage is 2-3BV(2 to 3 times the volume of resin),
the flow rate is 1-1.5BV/hr, and then the resin is rinsed with clean water
until PH to above 5.
c. Dilute NaOH
solution treatment
The
concentration is 4-5%, the dosage is 2-3BV(2 to 3 times the volume of resin),
the flow rate is 1-1.5BV/hr, and then the resin is rinsed with clean water
until PH to below 9.
d. Ion form
transformation of resin
According
to process requirements, when using hydrogen ion form, The operation steps can
be c first and then b; when using sodium ion form, The
operation steps can be b first and
then c; Generally, the new resin is
treated twice as described above.
e. Put into use.
7. Caution:
a. Eye irritant, avoid contact with eyes. in case of eye contact, immediatly flush eyes with plenty of clear water for 10 minutes.
b. Avoid child contact.
c. Dry resin on
floors may cause falls.
