We use the Tank Flow Rate Table 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 Boiler Feedwater Softening, to remove hardness at a flow rate of 25 GPM, use 10 GPM/SF as the Standard Service flow rate. To get to 25 gpm in the table, at 10 GPM/SF we see a 24 inch tank will work.
See Cartridge Type DI Systems for Cartrdge DI.
See Exchange Tank Type for small portable off-ste Regenerable Systems.
See Laboratory Water Systems for water used for solutions make-up in the lab.
Finally, we also determine from the table, how much water the softener will use for regeneration.
Backwash - 5 Minutes @ 5 GPM/SF
5 X 10.9 = 54.5 Gallons
Regen Draw - 17 Minutes @ 1.25 GPM/SF
17 X 3.9 = 66.3 Gallons
Slow Rinse - 60 Minutes @ 1.85 GPM/SF
60 X 5.8 = 348 Gallons
Fast Rinse - 6 Minutes @ 2 GPM/FT3 of resin
6 X 6(FT3) X 2 = 72 Gallons
Total Gallons Used = 540.8
You can use this approach for any Tank Type treatment process.
