5.2.4 Salt Use Table
Notes:
1. Flow rates for refill controls are based on 60 psig (414 kPa) inlet pressure.
2. Take into account the type of brine system used when determining the actual amount of salt delivered during
regeneration. (i.e. dry salt/grid plate or wet salt)
3. Salt Use Table reflects minimum salting of 6 lbs./cu.ft. (96.11 kg/m
3
) through maximum salting of 15 lbs./cu.ft.
(240.27 kg/m
3
).
4. To use potassium chloride (KCl) increase salt dosage by approximately 25%.
5. Chloride/Anion dealkalizers regenerate with 5 lbs./cu.ft. (80.09 kg/m
3
) salt (NaCl) which yields approx. 7500 gr/
cu. ft. Injecting sodium hydroxide (NaOH) i.e. caustic soda, at a rate of 1/10 that of the salt dosage, during the
brine draw cycle, increases capacity to approx. 10000 gr./cu. ft. Exact capacity, based on tank size, must be
calculated using water analysis and resin manufacturer’s capacity curves.
