Per minute example:

Target dose 2.0 ppm

Treated volume 5 gallons (assume this is a per minute flow value of 5 gpm through a pipe)

Assume % active is bleach at 6%

SG (specific gravity) let’s assume 1.1

All the results will be a per minute dosage value of raw 6% chemical to achieve 2.0 ppm in moving fluid so that is 0.02 fluid ounces fed per minute.

Total treated volume example:

For Example: mixing a batch of chemical in a feed tank:

Target dose 10.0 ppm

Treated volume 50 gallons (assume this is a per minute flow value so 5 gpm)

% active, let’s say bleach at 6%

SG (specific gravity) let’s assume 1.1

All the results will be total amount of chemical to add to 50 gallons to make a 10 ppm bulk solution mixture in this case 1.17 fluid ounces is required.

Note: it is most likely easier to make all these calculations in metric for smaller volume or flow values.
