Numbers in this table represent an approximation of the number of times in 12 days to regenerate
based on 6.5 Kgr/cu ft capacity of the resin (@ 9 lb /cu ft) as a result of the nitrate to n sulfate
ratio and 20% leakage of influent based on the nitrate to total anions ratio. Your capacity & leakage
may differ significantly from these figures. We recommend you contact First Sales technical services
with your test results and sizing information to have your regeneration schedule calculated more
precisely.
