Tank Based Carbon Filters

Tank Based Carbon Filters will remove Chlorine and Chloramines. Typically we see these units used on city water and occasionally on well water supplies.

Tank Based Carbon Filters can be single tank as well as Duplex and even Triplex depending on requirements.

Tank Based Carbon Filters can be either Fiberglass, Steel or even Stainless Steel.

Service and Reconditioning Values

Carbon Filters for Dechlorination

  • Service Flow Rates 10 to 15 GPM/SF – Standard 10
  • Backwash – 5 to 15 Minutes @ 10 GPM/SF

Forward Rinse – 2 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, city water at 50 GPM use 10 GPM/SF as the Standard Service flow rate. To get to 50 gpm in the table, at 10 GPM/SF we see a 30 inch tank will work.

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

  • Backwash – 12 Minutes @ 10 GPM/SF
    12 X 50 = 600 Gallons
  • Forward Rinse – 3 Minutes @ 10 GPM/SF
    3 X 50 = 150 Gallons
  • Total Gallons Used = 750
