Calculators - Injectors
These calculations are based on a known FLOW RATE of water through the device and a known FEED RATE of dechlorination solution (mixture of Vita-D-Chlor and water) into the device. This is useful for devices like the Dechlorinator and the H2O Neutralizer as well as homemade venturis. It is also for the use of metering pumps into a flow.

When using it, it is important to remember that your feed solution of Vita-D-Chlor and water has limitations. Generally no more than 1 pound of Vita-D-Chlor can be mixed into a gallon of water. This concentration can be increased to 4 pounds per gallon if you choose to use Vita-D-Chlor Neutral. The calculator equations are suitable for both VDC and VDC Neutral.

Enter the three parameters and click "Calculate".

Flow Rate in GPM
PPM of Chlorine
Feed Rate in GPH
Pounds per Gallon of Vita-D-Chlor
Grams per Gallon of Vita-D-Chlor

Pounds of Vita-D-Chlor per gallon of water = (Flow x PPM) / (750 x Feed)
Grams of Vita-D-Chlor per gallon of water = (3 x Flow x PPM) / (5 x Feed)


Flow=Flow rate of water through the device in gallons per minute (GPM)
PPM=Parts per million of Chlorine to be treated
Feed=Feed rate of dechlorination solution into the device in gallons per hour (GPH)

While the statements, information and data provided herein are believed to be accurate and reliable, they are presented without guarantee, warranty, or responsibility of any kind, expressed or implied. This information is based on general calculation for the dechlorinization capabilities of Vita-D-Chlorâ„¢. It is intended only to assist in determining the quantity of material to purchase and is not a statement of the actual quantity of Vita-D-Chlorâ„¢ required to neutralize chlorine. Different attributes of different water will affect your actual results. Prior to being released into the environment, all treated water must be tested to assure that complete dechlorinization has been achieved.
