To determine the frequency of regeneration, use this procedure:
Days:
Total amount of iron to be removed between regenerations -
÷ ppm of iron to be removed per day
= NUMBER OF DAYS BETWEEN REGENERATIONS
Example:
5 people in the household
x 60 gallons of filtered water per person
= 300 gallons of filtered per day
x 8 ppm of iron
= 2400 PPM OF IRON TO BE REMOVED PER DAY
Using 5600 SEM-948IF + 1 Feeder
6000 ppm capacity
÷ 2400 ppm to be removed per day
= 2 DAYS BETWEEN REGENERATIONS
Setting the Frequency of Automatic Regeneration (SE Models)
The number of gallons of filtered water your iron filter can supply between regenerations must first be
determined using the following calculations.
Gallons:
ppm of capacity between regenerations (see Specifications - Page 1)
÷ ppm of iron in the water sample*
= number of gallons supplied between regenerations
- reserve capacity (number of people x 60 gallons)
Example - Using 5600 SEM-948IF + 1 Feeder
6000 ppm between regenerations
÷ 8 ppm of iron
= 750 gallons between regenerations
- 300 gallons reserve capacity (5 people x 60 gallons)
= 450 GALLONS - BETWEEN REGENERATIONS
* 1 ppm of manganese = 2 ppm of iron; 1 ppm of hydrogen sulfide = 3 ppm of iron
