Greensand Iron Removal Filters Service and Reconditioning Values.

Greensand – Iron, Maganese & Sulfide

• Service Flow Rates 3 to 4 GPM/SF – Standard 3
• Backwash – 10 to 15 Minutes @ 12 GPM/SF
• Forward Rinse – 4 Minutes @ 10 GPM/SF

We use the Tank Flow Rate Table above and the Service & Reconditioning Values to estimate how a Tank Based Water System will work. You can first determine how large a tank based system you will need by looking at the Service Flow Rates and then checking for Tank Size in the table.

For example, for well water with iron at 25 GPM use 3 GPM/SF as the Standard Service flow rate. To get to 25 gpm in the table, at 3 GPM/SF we see a 42 inch tank will work.

Finally, we also determine from the table, how much water the filter will use for regeneration.

• Backwash – 10 Minutes @ 12 GPM/SF
  10 X 115.5 = 1155 Gallons
• Forward Rinse – 4 Minutes @ 12 GPM/SF
  4 X 115.5 = 620 Gallons
• Total Gallons Used = 1,775.0
